Dishwasher not filling with water

If your dishwasher is not filling with water, don’t panic. This is a common fault that can be fixed easily. We recommend trying to troubleshoot the problem by following the information provided below. If you do not feel confident about carrying out the following checks, please book an engineer visit.

Check if the dishwasher water supply valve is switched on before proceeding. It is easy to forget to switch it on, especially after coming back from a holiday. Be sure to also inspect for any visible damage.

Inspect the dishwasher hose and untwist any visible kinks or bends. Also ensure that the waste water hose is not blocked by removing the waste water hose from the siphon connection, putting the end of the hose in a bucket and selecting the drain programme. If there is a blockage, water will not fill, or struggle to fill the bucket. If a blockage is found, clean the waste water hose and siphon.

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.

If the filter is blocked with food remnants or other objects, the dishwasher will not drain the water from the previous cycle, which will prevent it from refilling. Ensure that the filter is unblocked before proceeding. For more information on how to clean the dishwasher filter, click here.
