Water tab error on my dishwasher

My Siemens dishwasher shows a water tab 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.

Step 1: Kinked or blocked hose.

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.

Step 1

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 visible kinks or bends in these hoses.

Step 2

Pull the appliance out slightly and untwist any visible kinks.

Step 2: Low water pressure.

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.

Step 1

Check the water pressure of the tap.
Close the water tap and remove the hose.

Step 2

Put a bucket below the tap and turn off the water tap. Approximately 10 liters of water per minute should come out.

Step 3

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.

Step 3: Filter blockage.

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.

Step 1

Turn off the water tap.

Step 2

Remove the hose from the water tap.

Step 3

Clear filter under running water.
Use a small brush to clean.

Step 4

Connect the hose and check for leaks.

Step 5

Step 6

Pull the appliance out slightly and untwist any visible kinks.
