Is your dishwasher not draining the water away? Before you call a repair service, here are three simple things you can try when your dishwasher won’t drain.
1. Start by cleaning the filter unit and check the pump
One reason for your dishwasher not draining completely could be a blocked filter or or blocked pump. Foreign objects, such as slivers of glass, food or dirt, can clog the dishwasher’s filters and/or pump resulting in the dishwasher not draining.

3. Check the drain hose is clear
A reason for the dishwasher not draining completely could simply be a kinked or twisted drain hose. Kinks and twists can prevent water flow and trap food and other debris.
Disconnect the machine from the power supply. Check the drain hose has no kinks or twists. If it does, try to straighten them out. There will likely be very hot water in the hose so carefully straighten it out and place one end in a bucket to drain.
Once the water has drained, feel along the hose with your hands for blockages, and check again for kinks. Clean the drain hose using the dishwasher “drain” programme, letting water run through the hose into a bucket. Use the opportunity to check the hose for leaks. You can also remove the hose from the dishwasher completely and clean it with hot water, although, if it is particularly dirty, it is a good idea to replace it.
Reconnect the drain hose and plug in the dishwasher. Set the dishwasher on its quickest cycle to test whether the dishwasher now drains properly.
