Maintenance

Cleaning the drain pump and non-return valve

If the water has not been pumped away at the end of a programme the drain pump or the non-return valve might be blocked. They are, however, easy to clean.

Disconnect the dishwasher from the mains supply. Switch off at the mains socket and withdraw the plug.

Take the filter combination out of the wash cabinet (see "Cleaning and care", "Cleaning the filters").

Scoop the water out of the cabinet using a suitable container or utensil.

Press the catch for the non-return valve inwards .

Lift out the non-return valve  and rinse well under running water.

Remove all foreign objects from the non-return valve.

The drain pump is situated under the non-return valve (see arrow).

Remove all foreign objects from the drain pump carefully (watch out for glass or bone splinters which are particularly difficult to detect and could cause injury). Turn the drain pump impeller by hand to check that there are no more obstructions. You will feel a little resistance when you turn the impeller.

Carefully replace the non-return valve, and secure it with the catch.

Ensure that the catch engages correctly.

Be very careful not to damage sensitive components when cleaning the drain pump and the non-return valve.
