Before you do anything else make sure you disconnect the appliance.

Door Seal

The door is probably the most commonly seen place for a dishwasher to leak and also one of the quickest problems to resolve.

If the leakage is occasional the problem might be as easy as a large plate or something else putting pressure into the door thus stopping the door from shutting properly.

On the other hand the door gasket may have come out of place or got damaged.

Examine the door seal and investigate for any brittleness, mineral deposits or other deposits, or any areas where the seal might have separated from the door.

Removing the seal and giving it a good wash has been known to help in some instances or you may need to acquire a new seal and replace it.

Water Inlet Valve (Solenoid Fill Valve)

The water inlet valve can also be a common problem. This is usually found underneath the machine which means you will have to take off the kick plate and could need to remove the door cover.

The fill valve opens and closes to let water into the machine at different parts of the programme. The fill valve could be leaking, demonstrated with a slight drip, or it may be damaged thus not opening or closing fully throughout the programme.

When the water inlet valve doesn’t close correctly this can mean that the dishwasher overfills, causing a leak.

In General water inlet valve can’t be repaired, thus the whole valve would have to be changed.

Leaking Hoses

Your dishwasher uses hoses to fill, empty as well as recirculate water during the programme.

Two issues can develop when it comes to hoses.

  1. The seals may break or the connections can come loose meaning it’s worth examining all the connections .
  2. The alternative issue than might often develop as you use the machine is that hoses might become damaged or cracked.

Luckily faulty hoses are relatively simple to buy and change.

Pumps and Seals

You can visually check the rubber seals surrounding the pumps or motor to see if there is a leak and change them if there is.

The Float Switch

Either the float or the float switch might be not working correctly resulting in the dishwasher overfilling.

When operating correctly the float will lift up as the water rises until it reaches the highest fill level. The tail of the float should then turn on the switch. A blockage or breakage could be causing your issues.

Testing the switch would need a multi-meter although it may be noticeably broken in which case replacing it should fix the problem.

Other Parts that Might Lead to Leakage
