Excessive foam occurs - Hand washing-up liquid or wrong detergent
Too much foam is generated inside the dishwasher during operation, which can be caused by using hand washing-up liquid or an unsuitable detergent.
Filling valves making knocking noises - Due to domestic installation
A knocking noise is heard from the filling valves. This is not an appliance fault but is caused by the domestic water installation and does not affect the appliance's functioning.
Remnants of food on tableware - Improper loading or blocked spray/filters
Dishes still have food residue after a wash cycle, which can be due to incorrect loading, blocked spray arms or filters, or an unsuitable wash program.
Home Connect cannot be implemented correctly - Incorrect setup or technical fault
The Home Connect features are not functioning as expected, possibly due to incorrect setup or an underlying technical fault with the system.
Connection to home network not established - WLAN inactive
The appliance cannot connect to the home network, likely due to the WLAN (Wi-Fi) on the router being inactive.
Irreversible clouding of glassware - Non-dishwasher-proof glasses or lengthy steam phase
Glasses appear permanently cloudy, indicating damage rather than residue. This can be due to using non-dishwasher-proof glassware, or exposure to a lengthy steam phase.
Knocking or rattling noise - Spray arm striking tableware or small load
A knocking or rattling sound is heard during operation, often due to the spray arm hitting items in the dishwasher, or water jets striking the tub with a small load.
Plastic parts inside the appliance are discoloured - Normal wear or low wash temperature
Plastic components inside the dishwasher have changed colour over time. This is often a normal part of the appliance's life, or can be influenced by wash temperature or intensive precleaning.
Programme starts automatically - Programme not fully terminated
The dishwasher programme starts by itself without user initiation, likely because the previous programme was not fully terminated.
Removable streaks on glasses, glassware, and cutlery - Rinse aid dosage or detergent issue
Streaks or film that can be removed are visible on glasses, metallic glassware, and cutlery after the wash cycle.
Refill indicator for rinse aid lights up - Insufficient rinse aid
The rinse aid refill indicator is illuminated, signaling that the rinse aid level in the dispenser is low and needs to be refilled.
Rust spots on cutlery - Washing with rusting items or non-resistant cutlery
Rust spots appear on cutlery after washing. This can happen if rust-prone items are washed together with the cutlery, or if the cutlery itself is not sufficiently rust-resistant.

Persistent white film or deposits are visible on dishes, or inside the dishwasher and on the door, which are difficult to remove.
Tableware is not dry - Insufficient rinse aid or incorrect program/settings
Dishes and cutlery remain wet after the wash cycle, which can be due to a lack of rinse aid, improper program selection, or incorrect loading.
Tea residue or lipstick marks on tableware - Low washing temperature or wrong detergent
Dishes still have visible tea stains or lipstick marks after the wash cycle, indicating insufficient cleaning.
WLAN display flashing - Home network connection unavailable
The WLAN display on the appliance is flashing, indicating that a connection to the home network is not currently available.

Water remains in the dishwasher tub after the programme has finished, indicating a problem with drainage.
Water marks on plastic parts - Condensation drying or no rinse aid
Visible water marks remain on plastic items or parts inside the appliance after the drying cycle. This is often due to the physical properties of plastic or insufficient rinse aid.
