My dishwasher shows a water tap error in the display

Our dishwashers are fitted with a self-diagnosis system, which in the rare case of a fault will help to report what the problem is. If the symbol “water tap” appears on the display of your dishwasher please follow these 3 steps to resolve the problem.

Follow the steps in the video to resolve this issue easily and on your own:

Inspect the dishwasher supply hose and untwist any visible kinks or bends.

Step-by-step guide: How to check that there are no kinks in the supply hose.

The supply hose may be kinked.

Check that there are no kinks in the cold water fill hose and the waste water hose by pulling the appliance out slightly and untwisting any visable kinks or bends in these hoses.

Pull the appliance out slightly and untwist any visible kinks.

Check the water pressure directly from the tap using a bucket. Approximately 10 litres of water per minute should flow out of the tap when fully open. Contact your fitter if the water pressure is too low.

Step-by-step guide: How to check the water pressure

Check the water pressure of the tap.

Close the water tap and remove the hose.

Put a bucket below the tap and turn off the water tap.

Approximately 10 liters of water per minute should come out.

If the water pressure is too low, please contact your plumber to check the water installation.

If you could not solve the problem, please close the water tap and switch off the appliance. Book an appointment with one of our engineers who will be able to professionally rectify the problem.

If the filters in the water connection of the supply or AquaStop hose are blocked, make sure to clean the filter in the inlet hose.

Step-by-step guide: How to clean the inlet filter

Remove the hose from the water tap.

Clear the filter under running water.

Use a small brush to clean.
