Cleaning & Care

Appliance
How to clean the interior of the dishwasher. We recommend using FINISH® Dishwasher Cleaner. The cleaning frequency depends on how often you use your dishwasher and the water hardness of the area you live in. If you see white or grey residue on the inside of your dishwasher, it’s time to clean it.

FINISH® Dishwasher Cleaner works by safely and effectively breaking down and removing mineral build-up from the interior of your machine, including hard-to-reach parts like the spray arms. Cleaning your dishwasher on a regular basis may extend the life of your dishwasher and improve its performance.

Here's how to use FINISH® Dishwasher Cleaner:

  • 1. Remove the sticker from the top of the bottle without removing the cap.
  • 2. Make sure your dishwasher is empty.
  • 3. Place the bottle upside down on the lower rack in a secure place, such as where you would place a small dish.
  • 4. Run the dishwasher on the hottest and longest cycle.
You can purchase FINISH® Dishwasher Cleaner at your local supermarket.
How to clean stains in the dishwasher. Stains on the interior of the dishwasher are generally due to (1) water hardness (white mineral build-up) or (2) silverware in contact with the tub (discolored stains).

  • 1. For water hardness stains (white mineral build-up), use a dishwasher cleaner to remove these stains. It will break down and remove mineral build-up.
  • 2. To prevent stains on the tub, ensure the silverware does not come in contact with the tub during the wash cycle. Use a dishwasher cleaner to remove stains.
We recommend using FINISH® Dishwasher Cleaner to clean your dishwasher. Purchase the cleaner at your local supermarket.

Never use a steam cleaner to clean your dishwasher.
How to prevent rust-like spots in your dishwasher. Rust-like spots can appear on your dishwasher tub if the silverware is in contact with the tub during a wash cycle. Ensure the silverware does not come in contact with the tub during the wash cycle.
How to clean the door seal of the dishwasher. Wipe the door seal with a damp cloth. Dry with a soft cloth.
How to clean the exterior of my dishwasher. Stainless steel surfaces - Clean stainless steel areas by using mild soapy water with a soft cloth. Wipe in the direction of the stainless steel grain when washing and drying. Rinse with water and wipe dry to avoid watermarks. Do not use cleaners that are abrasive or contain chlorine since both are corrosive to stainless steel. For added shine, apply a stainless steel conditioner and wipe off the excess with a soft cloth.

Visit the How-To Videos page and watch the "Cleaning Stainless Steel Appliances" video to learn more.

Stainless steel conditioners and cleaners can have negative effects on materials other than stainless steel. Do not apply stainless steel conditioners and cleaners to control markings, labels, logos, black or smudge-proof stainless steel, and appliance interiors.

Non-stainless steel surfaces - Wipe the front of the appliance with a damp cloth. Do not use abrasive detergents or sponges with a rough surface.

Descaling & Softener Salt
How often and how do I descale my dishwasher? Descale the dishwasher if there are limescale deposits. We recommend descaling your dishwasher at least once a year.

Here's how to descale your dishwasher:

  • 1. Run the hottest, regular cycle without detergent or dishes.
  • 2. After 30 minutes, open the dishwasher with caution and add the descaler to the bottom of the dishwasher. Close the dishwasher and restart the cycle.
  • 3. After the cycle has finished, run another wash cycle for a thorough cleaning.
How to use softener salt. Not all dishwasher models use softener salt. Please refer to your owner’s manual to see if this applies to your dishwasher. If you do not have an owner's manual, you can download it here.

Add softener salt regularly by following the instructions in your owner's manual. The salt will help soften the water used in the dishwasher and reduce hard water deposits.

Visit the How-To Videos page and watch the "Loading Salt in Dishwasher" video to learn more.

Usage & Operation

Power & Malfunction
How to reset the dishwasher. Please refer to your owner's manual to learn how to reset your dishwasher. If you do not have an owner's manual, you can download it here.
The dishwasher display does not light up. There are several solutions for this problem:

  • The power switch may not be switched on. Push the power switch on.
  • For models with the controls on the top portion of the door, the display will only illuminate when the door is opened and the controls are visible.
  • For certain models that have the controls on the face of the dishwasher, the display will only illuminate when the door is closed.
The dishwasher is not filling with water. There are several solutions for this problem:

  • The previous wash cycle was not completed before unloading your items. To complete the cycle, reset the dishwasher according to the instructions in your owner's manual. If you do not have an owner's manual, you can download it here.
  • The water supply may be blocked. Check that the water supply valve (typically located under the kitchen sink) is open and ensure that the water supply line has no kinks or clogs. To ensure the water supply line has no kinks or clogs, shut off the supply, disconnect the hose, and flush the line by passing 7.5 liters of water through the line. Check and ensure the household water supply is not turned off.
  • The delay start is active. Cancel the delay start or wait until the delay is complete.
The desired cycle cannot be selected or the cycle time adjusts in the middle of a wash cycle. If you are unable to select a cycle, the previous cycle may not have finished. Refer to the "Operating the Dishwasher" section of your owner's manual for instructions. If you do not have an owner's manual, you can download it here.

If you notice the cycle time adjusts in the middle of a wash cycle, this is normal. The dishwasher uses sensors to detect the amount of soil in the wash water and adjusts wash conditions based on this information to ensure a proper wash is achieved. The display changes accordingly during the cycle.
The dishwasher is running for a long time. The dishwasher runs for a longer time due to the following reasons:

  • The incoming water is not hot enough. If this happens, the wash cycle will extend to heat the water internally in the dishwasher’s heat pump. To reduce wash time, briefly run the hot water faucet at the sink closest to the dishwasher before starting the dishwasher.
  • Heavily soiled dishes can prolong the washing time. The sensors in the dishwasher extend the cycle time to wash off heavy food soils.
  • The rinse aid dispenser is empty. The dishwasher extends cycle time to compensate for the lack of rinse aid by adding a longer final rinse. Add rinse aid to avoid this.
  • The dishwasher is connected to a cold water supply. The wash cycle extends to heat the water internally in the dishwasher’s heat pump. Connect the dishwasher to a hot water source to reduce run time.
The dishwasher won't drain. There are several solutions for this problem:

  • The drain lines are blocked. Check the drain lines for blockages in the garbage disposal and air gap. After clearing the blockage, select the CANCEL / DRAIN program.
  • The drain pump is blocked by debris. Empty the water from inside the dishwasher using a ladle or something similar. Consult your owner's manual to learn how to unblock the drain pump. In the future, scrape off large debris on the dishes before placing them into the dishwasher.
  • The dishwasher filter may not be clean. Refer to your owner's manual to learn how to properly remove the filter. Rinse the filter and its components under lukewarm water. Gently use a scrub brush to remove particles. Rinse and dry with a soft cloth. Visit the How-To Videos page and watch the "Cleaning Your Dishwasher Filter" video to learn more.
If you do not have an owner's manual, you can download it here.

Please note, the drain hose must have a “high loop” between 20” and 50” above the floor to pump properly. Consult the installation instructions for more details. You can download the installation instructions here. If the drain extension is used, ensure the max length of the drain hose, including the hose leading to the air gap, is no more than 150”.
The filter is blocked. If the filter is blocked, remove the filter from the bottom of the dishwasher. Please refer to your owner's manual to learn how to locate and remove the filter. If you do not have an owner's manual, you can download it here. Remove any debris from the filter and wash it under running water. Gently use a scrub to remove any particles that are still stuck on the filter. Dry and properly reinstall in the dishwasher.

Visit the How-To Videos page and watch the "Cleaning Your Dishwasher Filter" video to learn more.
Noise / Sound
There is noise during the wash cycle. The water circulation sound is normal. If you suspect items are banging into each other or into the spray arms, refer to your owner’s manual for optimal arrangement. If you do not have an owner's manual, you can download it here.
The dishwasher beeps. The dishwasher beeps when a dishwashing cycle has finished. This feature can be deactivated if desired. To deactivate this feature or adjust the volume, refer to your owner's manual. If you do not have an owner's manual, you can download it here.
Loading the Dishwasher & Rinse Aid
How to load the dishwasher. Silverware - The knives should be placed in the cutlery basket with the blades facing downwards for safety reasons. Place forks and spoons into the cutlery basket with the top of the utensil facing up or down. Mix it up so the spoons and forks don’t nest into each other which could result in less efficient cleaning.

Dishes - On the left side of the dishwasher, load the dishes so they face inwards towards the center. On the right side of the dishwasher, load the dishes so they face inwards towards the center.

Bowls - Place the bowls on their sides for maximum exposure to the water flow. Do not place them facing completely downwards as this limits their exposure to the water flow.

Large pans & platters - Place these items along the outer sides of the lower rack.

Stemware & cups - Load these on an angle to limit the amount of standing water after the wash cycle is complete. Loading on an angle allows water to slide off the cups.

Plastics - Plastic items can be placed on the upper or lower rack because Thermador dishwashers do not contain a heating element at the bottom of the dishwasher.

Visit the How-To Videos page and watch the "Loading Your Dishwasher" video to learn more.
Do I need to pre-rinse items before loading them in the dishwasher? No. Just scrape food, bones, and other heavy debris off the dishes and place the dishes into the dishwasher. Dishwasher detergents contain enzymes, which find food particles and break them down. If there is no food to cling to, the enzymes can damage your dishware resulting in etched or cloudy glasses and dishes over time.
What items should not be washed in the dishwasher? In general, anything that is not marked "dishwasher proof" or "dishwasher safe" should not be washed in the dishwasher.


Below is a more detailed list of materials / items that should not be washed in the dishwasher:

  • Acrylic - Crazing or small cracks may occur.
  • Adhesive-joined pieces - Adhesives that join materials such as plastic, wood, bone, steel, copper, and tin may loosen.
  • Bone-handled utensils - The handles may separate.
  • Iron - Iron will rust.
  • Non-dishware items - Your dishwasher is intended for ONLY cleaning standard household dishware and kitchenware.
  • Pewter, brass, bronze - These items will tarnish.
What is the largest diameter plate or pan that can fit in the upper and lower rack? The upper rack can hold a 10" plate and the lower rack can hold a 12" plate. A 24" cookie sheet will fit in the lower rack when the upper rack is removed.
How to wash large items. Remove the upper dishwasher rack. Then, install the Large Item Spray Head on the back of the dishwasher wall. Visit the How-To Videos page and watch the "Installing the Large Item Spray Head" video to learn more.

Refer to your owner's manual to see which Large Item Spray Head your dishwasher needs and click here to learn how to purchase it. If you do not have an owner's manual, you can download it here.
How to aid rinse aid. Here's how to add rinse aid:

  • 1. Open the rinse aid dispenser cover and add the liquid rinse aid to the dispenser until it is full.
  • 2. Wipe off any excess rinse aid that spills outside the dispenser.
  • 3. Set the amount of rinse aid the dishwasher should dispense during each cycle. Refer to your owner's manual to learn how to do this. If you do not have an owner's manual, you can download it here.
The dishwasher will indicate if the rinse aid amount is low by illuminating a light or text.

Visit the How-To Videos page and watch the "How to Add Dishwasher Rinse Aid" video to learn more.
How many washes will the rinse aid dispenser handle? A full dispenser will hold enough for about 30 washes.
Unsatisfactory Cleaning & Drying Results
The utensils are not clean. Be sure to avoid nesting your utensils, which will prevent them from being properly cleaned.
There are streaks on the dishes. Reduce the amount of rinse aid.
The dishwasher does not wash thoroughly. There are several solutions for this problem:

  • Spray arm movement may be obstructed – Manually spin each spray arm to ensure they are not blocked. They should rotate freely.
  • Spray arm nozzles are clogged – Remove the spray arms and rinse them under water to loosen debris. Use a toothpick to remove any debris in the holes. After cleaning, reinstall the spray arms. Visit the How-To Videos page and watch the "Cleaning Dishwasher Spray Arms" video to learn more.
  • Improper use of detergents – Increase or decrease the amount of detergent depending on the water hardness and food debris. Please refer to your owner's manual for more information.
  • Clogged filter – Remove and rinse the filter and its components under lukewarm water. Gently use a scrub brush to remove the particles. Rinse and dry with a soft cloth. Visit the How-To Videos page and watch the "Cleaning Your Dishwasher Filter" video to learn more.
  • Dishes are nested or loaded too close together – Rearrange your dishware so the water from the spray arms can reach all items in the dishwasher. Refer to your owner's manual to learn how to properly load your dishwasher. You can also visit the How-To Videos page and watch the "Loading Your Dishwasher" video to learn more.
  • Wash cycle is unsuitable for the level of food debris – Select the correct wash cycle for your dish load. Refer to your owner's manual to learn which cycle to select.
If you do not have an owner's manual, you can download it here.
There are water spots or stains on the glassware. There are two primary reasons for this – hard water and etching. Wash the glass in a bowl of vinegar. If the cloudiness disappears, it is caused by hard water. If the cloudiness does not disappear, it is caused by etching.

  • If it is caused by hard water, adjust the amount of detergent used in the dishwasher. The amount may vary depending on the level of water hardness. You may need to increase the amount of rinse aid dispensed during the washing cycle. Please refer to your owner's manual to learn how to adjust the rinse aid setting. If you do not have an owner's manual, you can download it here.
  • If the cloudiness is caused by etching, it is permanent. You can prevent etching by not pre-rinsing the dishes, using a light wash cycle for glasses, and using the correct amount of detergent (not more than needed).
There is white coating or limescale on the utensils or inside the dishwasher. There are several solutions for this problem:

  • Make sure your water softening system has been set correctly according to your owner's manual. If required, refill with softener salt. Visit the How-To Videos page and watch the "Loading Salt in Dishwasher" video to learn more. Not every dishwasher model uses softener salt so please refer to your owner’s manual to see if this applies to your dishwasher. If you do not have an owner's manual, you can download it here.
  • If the salt compartment cap is not closed properly, there can be a coating of salt in the machine. Make sure the compartment is closed properly.
  • If there is limescale on the inside of the dishwasher, use a descaler to remove the limescale. This will also prevent damage to the heating system.
The dishwasher dries poorly. There are several solutions for this problem:

  • The rinse aid setting needs to be adjusted up. Please refer to your owner's manual to learn how to adjust it.
  • A cycle without drying was selected. Make sure to select a cycle with drying.
  • The dishes are not arranged properly. Make sure to arrange your dishes in a sloping position. Refer to your owner's manual to learn how to properly arrange your dishes. You can also visit the How-To Videos page and watch the "Loading Your Dishwasher" video to learn more.
  • The detergent used has a poor drying performance. Use a different detergent with a better drying performance. You can also use rinse aid to increase the drying performance.
  • Select models have Extra Dry which can be used to increase drying performance. Instructions for activating this function are in your owner's manual. This option adds extra heat to the final rinse and will enhance drying results.
If you do not have an owner's manual, you can download it here.

Please note, plastics take longer to dry than other materials.
What is condensation drying? All Thermador dishwashers use the condensation drying process to dry items in the dishwasher. Condensation drying does not utilize a heating element at the bottom of a dishwasher. Instead, it involves a number of dishwashing elements that result in an energy-efficient, high-quality drying process:

  • The final rinse uses water that has been heated to a very high temperature. This makes the dishware very hot when the rinse cycle ends.
  • The stainless steel tub of the dishwasher cools faster than the dishware because stainless steel typically cools faster than dishware materials (such as glass and porcelain).
  • Moist air is released from the hot dishware. When this moist air comes into contact with the cooler stainless steel tub, it turns into water droplets (condensation). These water droplets trickle down to the bottom of the dishwasher and are drained in the next wash.
  • Dishware and cups become dry during this condensation process. Plastics tend to have more difficulty drying because plastic does not heat up to a high temperature during the final rinse like glass / porcelain does.
The use of rinse aid, such as Jet Dry®, helps the condensation drying process by reducing the surface tension of water, thus encouraging water to run off dishware effortlessly. We have extensive experience with Jet Dry® and Jet Dry® Turbo Dry® and highly recommend either product to help create an optimal drying experience that reduces the chance of spots and other leftover residues. Approximately 3.5 drops of rinse aid are dispensed during each wash cycle. Use Jet Dry® for your regular drying needs. Use Turbo Dry® if you are drying a lot of plastic in the dishwasher or if you are already using a detergent with a rinse aid included in it and it’s still not drying adequately. Purchase these at your local supermarket.
Moisture & Odors
There is water at the bottom of the dishwasher. A small amount of water around the filter is normal.
The water is leaking from the door. Water leakage may be caused by the following:

  • The incorrect detergent was used - Only use dishwasher detergents. Do not use dish detergents. If suds persist, add one tablespoon of vegetable oil to the bottom of the dishwasher and run the desired cycle.
  • The door seal pulled away - The door seal may have caught on dishes that extend beyond the sides of the dishwasher rack. Push the seal back into place (near the inside edge of the dishwasher).
  • The condensation vent is blocked - Remove anything that is blocking the condensation vent (on the side of the dishwasher). Blocking this can cause the dishwasher to leak from the door instead of venting properly via the condensation vent.
  • The dishwasher is improperly installed - The dishwasher “feet” must be leveled properly. If not, gaps at the top of the dishwasher door may occur. In this case, adjust the “feet” accordingly. Please also have the installation verified by qualified personnel. They should check the water supply, drainage, leveling, and plumbing.
The dishwasher contains a lot of odors. Odors can occur in the dishwasher due to the following reasons:

  • This may be caused by infrequent usage. Run a pre-rinse program once in a while to help prevent odors. You can also use a dishwasher cleaner to maintain your dishwasher and keep it clean.
  • There is food debris on the bottom of the dishwasher and the filter needs to be cleaned. Remove the filter and rinse it under lukewarm water. Gently use a scrub brush to remove particles. Rinse and dry with a soft cloth. Visit the How-To Videos page and watch the "Cleaning Your Dishwasher Filter" video to learn more.
  • There are food particles near the door seal. Wipe with a damp cloth and dry with a soft cloth.
  • There is residual water at the bottom of the dishwasher. Ensure the unit has completely drained from the last cycle. Refer to your owner's manual to learn how to activate the drain. If you do not have an owner's manual, you can download it here.
  • The drain hose is obstructed. You will need to have an authorized Thermador servicer remove any obstructions from the drain hose. Click here to schedule a service visit. Ensure the drain hose high loop is between 20” and 50” above the ground.

Detergent
What detergents do we recommend? Below are several detergents we recommend:

  • Premium tabs such as Quantum® and Powerball® have an edge in performance over powder.
  • Powders are economical to use and the amount used can be adjusted according to the load size, water hardness, and / or the cycle selected.
  • Additives such as Power Up® Boost help combat hard water build-up.
  • Additives such as Jet Dry® and Turbo Dry® aid with drying large amounts of plastic items.
Visit the How-To Videos page and watch the "Choosing the Right Dishwashing Detergent" video to learn more.
What is the difference between liquid, gel, and powdered detergents? Liquid or gel detergents only contain one type of cleaning agent. Powdered and mono-dose products typically contain both types of cleaning agents (one for bleaching and one for cleaning food off dishware). Mono-dose products are also concentrated forms of powder and gel.
Information on phosphate-free detergents. In 2010, detergent manufacturers removed phosphates from all of their dishwashing products in response to laws banning phosphate-containing detergents. Many consumers are not aware of this detergent change and sometimes notice a white film on their dishware after using their dishwasher.

Here are some tips for optimizing the effectiveness of your phosphate-free detergent:

  • We recommend powder, tablets, or tabs. Tabs generally perform slightly better than powdered formulations. However, powdered formulations offer the flexibility to change the quantity used in the dishwasher. For example, one may add more or less powder to the dishwasher depending on load size, water hardness, and / or the cycle selected.
  • Using rinse aid helps water slide off dishware effectively in the final rinse and reduces the likelihood of spotting or streaking. If your detergent tablet already has rinse aid in it, it may still be helpful to add rinse aid to your dishwasher’s rinse aid dispenser. For persistent spotting on your dishware, increase the amount of rinse aid that your dishwasher dispenses. For streaks, decrease the amount. Please refer to your owner's manual to learn how to do this. If you do not have an owner's manual, you can download it here.
Rinse Aid
What is rinse aid? The use of rinse aid, such as Jet Dry®, aids the condensation drying process by reducing the surface tension of water, thus encouraging water to run off dishware effortlessly. We have extensive experience with Jet Dry® and Turbo Dry® and highly recommend either product to help create an optimal drying experience that reduces the chance of spots and other residues.

A very small amount of rinse aid is dispensed during each wash cycle (approximately 3.5 drops).

Use Jet Dry® for your regular drying needs. Use Turbo Dry® if you are drying a lot of plastic in the dishwasher or if you are already using a detergent with a rinse aid included in it and it’s still not drying adequately.

It is completely ok to add Turbo Dry® in the rinse aid dispenser if Jet Dry® is still in there. It is safe to mix these two. There is no need to empty out the dispenser before adding another rinse aid.
How to add rinse aid to your dishwasher. Here's how to add rinse aid:

  • 1. Open the dispenser cover.
  • 2. Fill the dispenser with liquid rinse aid until it is full. Wipe off any excess rinse aid that spills outside of the dispenser.
  • 3. Set the amount of rinse aid that the dishwasher should dispense during each cycle. Refer to your owner's manual to learn how to do this. If you do not have an owner's manual, you can download it here.
  • 4. The dishwasher will indicate if the rinse aid amount is low by illuminating a light or text on your dishwasher control panel.
