The app shuts itself down. Close the app and restart it. If it still does not work, update or reinstall the app.
The Android push messages are not displayed at the end of a program. If you use additional programs (e.g., Battery Optimizer, System Tools, and Software Manager), they may influence the notification function. Please reinstall the Home Connect® app after a system update of your smartphone / tablet.
There is no Home Connect® function found on the appliance. Check whether the appliance control panel has the Home Connect® function. Is the appliance connected and switched on? You can also refer to your owner's manual to learn if your appliance has the Home Connect® function. If you do not have an owner's manual, you can download it here.
The appliance is no longer available in the Home Connect® app. There is one Super User per appliance. This is the user who is the first to connect the appliance with their Home Connect® app. If the Super User deletes an appliance from their app, it will also be deleted from the app of the other users. The standard user can only delete an appliance from his user account. You will need to connect the appliance with the app again.
The appliance cannot be controlled away from home. Check to see if the appliance is connected to the internet. If the appliance is already connected, check if the remote function is activated on the appliance and make sure the internet speed is a minimum of 2 Mbit / second.
The appliance has reset to the factory settings. Resetting an appliance removes it from the Home Connect® app. Please connect the appliance with the internet router again and re-register the appliance in the app.

Syncing & Connection
The Wi-Fi signal is not detected by the appliance. A Wi-Fi router must be available. The router must be suitable for WPA / WPA2 encryption and must transmit at 2.4 GHz or 5.0 GHz. (Note: The coffee machine only supports 2.4 GHz). No restrictions should be set on the router (ports, MAC address, etc.).
The appliance cannot connect to the router. This may happen if the Wi-Fi is turned off on the appliance, if the Wi-Fi signal is weak at the appliance, or if the router is not working properly (i.e. not sending out a Wi-Fi signal). If the router is working properly, switch on the Wi-Fi on the appliance via the menu control. If the Wi-Fi signal is weak, you will need to amplify the signal. You can use a Wi-Fi repeater or a powerline adapter with the Wi-Fi function to amplify the signal.
The appliance is not connecting to the router through the Wi-Fi Protected Setup (WPS) function. This happens when the WPS function on the router is disabled or if there is no WPS button on the router. Check the operating instructions of the router to find out whether WPS is supported and if so, how to activate it. If WPS is not supported by the router, use the manual connection mode in the Home Connect® menu.
The appliance cannot connect with the Wi-Fi. Make sure your router is working properly and switch on the Wi-Fi on the appliance using the menu. Boost the Wi-Fi signal with a Wi-Fi repeater or use the powerline interface (dLAN) with the Wi-Fi function.
The Home Connect® app cannot establish a connection to the appliance. There are several solutions for this problem:

  • The router is turned off. Make sure the router is on.
  • The Wi-Fi password has been changed on the router and not on the appliance. Make sure to enter the correct password.
