How do I clean the detergent solution pump if it becomes blocked?

First, remove the service panel and drain out the water using the drain hose before carefully unscrewing the pump cover. Clean the interior, pump cover thread, and pump housing, ensuring the impeller inside the pump can rotate freely. Refit and tightly screw on the pump cover, then pour 1 litre of water into compartment II and run the Empty programme to prevent unused detergent from flowing into the drain. (Page 18)
