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

Door Gasket

The door is probably the most common area for leakage as well as one of the easiest problems to resolve.

If the leak is intermittent the problem might be as straightforward as an oversize dish or something else pushing against the door thus preventing it from sealing correctly.

Otherwise the door seal might have been dislodged or got cracked.

Examine the door seal and also test for any brittleness, a build-up of limescale or other deposits, or any areas where the seal has come away from the door.

Extracting the gasket and also giving it a thorough scrub has been known to help in some cases or you might be required to acquire a new gasket and change it.

Water Inlet Valve (Solenoid Fill Valve)

The inlet valve can also be a commonplace issue. The Valve is generally situated on the underbelly of the machine which means you will need to remove the kick plate and also may need to remove the door cover.

The water inlet valve opens and closes to let water into the dishwasher at varying times in the program. The water inlet valve might be damaged, evidenced with a slight drip, or it could be broken thus not operating fully while the dishwasher is running.

If the fill valve fails to close fully this can result in the dishwasher leaking.

Usually inlet valve cannot be refurbished, thus the whole component would need to be replaced.

Leaking Hoses

Hoses are needed to supply, empty and also recirculate water within the cycle.

Two complications may present themselves with hoses.

  1. The gaskets could get damaged or the connections can come loose so it’s worth examining all the connection points .
  2. The other problem than might often develop as time goes by is that hoses could become broken or get a hole in.

Luckily damaged hoses are easy to get hold of and replace, even for a novice.

Pumps and Seals

You can visually investigate the rubber seals around the water pumps or motor to see whether there is a leakage and replace them if there is.

The Float Switch

The float itself or the float switch could be damaged causing the dishwasher to overfill.

A working float will rise as the water rises until the optimum or highest water level is attained. The tag of the float would then turn on the switch. If something is blocking this or the float is broken this could be your issues.

Testing the switch will require electrical equipment although it might be clearly broken in which case replacing it should stop the leak.

Other Parts that Could Cause a Leak

A damaged wash arm or support could causing a leak. This can also often result in your dishes not being cleaned as effectively as they should.

Broken or cracked tubes may also result in this problem as could a broken pump cover if your machine has one.

The motor shaft seal could have degraded causing leakage. This will generally show as leakage coming from underneath the dishwasher.
