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

Door Seal

The most commonly seen place for a dishwasher to leak is on the door, luckily it is likewise one of the quickest problems to resolve.

If the leak is periodic the problem may be as simple as a big pan or another object putting pressure into the door and stopping the door from sealing fully.

Else-ways the door seal may have come loose or become cracked.

Taking off the seal and also allowing it a thorough scrub can help in some cases or you may have to buy a new seal and change it.

Water Inlet Valve (Solenoid Fill Valve)

The inlet valve can also be a common issue. The Valve is generally situated under the machine and so you will most likely need to remove the toe board and might need to unscrew the door cover.

The water inlet valve opens and closes to allow water into the tub at varying times during the cycle. The fill valve may be leaking, demonstrated by a slight drip, or it may be damaged thus not opening or closing properly while the dishwasher is running.

If the water inlet valve fails to close correctly this can lead to the dishwasher leaking.

In General these valves can’t be fixed, and so the whole component would have to be changed.

Leaking Hoses

Your dishwasher uses hoses to fill, drain and also recirculate water along the cycle.

Two problems can present themselves where hoses are concerned.

  1. The seals may get damaged or the connections could work loose so it’s worth checking all the connections first.
  2. The alternative issue than can easily happen as time goes by is that hoses could get damaged or get a hole in.

If you are able to determine that the leakage is coming from a hose this should be relatively simple to change and replacement hoses are readily available.

Pumps and Gaskets

You are able to visually test the rubber gaskets that are part of the pumps or motor to determine whether there is a leak and also change them if that’s the case.

The Float Switch

Either the float or the float switch could be faulty causing the dishwasher to overfill.

When working as it should the float will rise as the water level goes up until the optimum or maximum water level is reached. The tail of the float should then activate the switch. If something is blocking this or the float is broken this could be causing your problem.

Testing the switch will require electrical equipment but it may be noticeably broken in which case replacing it should solve the problem.

Other Parts that May Result in Leakage
