Teka · Dishwashers
A knocking noise inside the wash cabinet is usually caused by a spray arm hitting an item in a basket or items of crockery being loose.
Click steps to track your progress.
Interrupt the program and open the Dishwasher door.
Rearrange the items in the baskets to ensure they do not obstruct the spray arms.
Make sure all dishes, glasses, and cutlery are securely placed in their respective holders.
Close the door to resume the program and check if the noise has stopped.
