Door Gasket

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

If the leakage is periodic the problem might be as simple as an oversized dish or something else pushing into the door and preventing the door from shutting fully.

On the other hand the door seal might have come loose or become split.

Examine the door seal and also test for any degradation, a build-up of limescale or other gunk, or any areas in which the gasket might have come away from the door.

Taking off the gasket and allowing it a good wash can improve the situation in some cases or you could need to purchase a new gasket and replace it.

Water Inlet Valve (Solenoid Fill Valve)

The inlet valve can be a further simple problem. This is usually located underneath the machine therefore you may need to unscrew the kick plate and also may need to remove the door cover.

The inlet valve opens and closes to allow water into the dishwasher at varying parts of the cycle. The water inlet valve could be leaking, shown by a slight drip, or it may be damaged and not operating fully throughout the cycle.

When the water inlet valve fails to close properly this can mean that the dishwasher overfills, causing a leak.

Often fill valve are not able to be fixed unless it is only the rubber gasket that is damaged, thus the entire valve would have to be replaced.

Leaking Hoses

Hoses are needed to fill, empty and also recirculate water within the programme.

Two problems could arise when it comes to hoses.

  1. The gaskets can get damaged or the connections could work loose so it’s worth having a look at all the connections .
  2. The alternative problem than may often happen as time goes by is that hoses might get broken or cracked.

Luckily faulty hoses are simple to buy and also change, even for a novice.

Pumps and Seals

You can visually test the gaskets around the pumps or motor to determine whether there is a leak and replace them if that’s the case.

The Float Switch

The float itself or the float switch may be broken resulting in the dishwasher overfilling.

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

Checking the switch would need a multi-meter but it might be noticeably damaged in which case getting a new one should solve the leak.

Alternative Parts that Could Result in Leakage

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