Door Gasket

The most commonplace place for a dishwasher to leak is on the door, luckily it is likewise one of the simplest issues to solve.

If the leak is intermittent the issue could be as easy as a large plate or something else pushing against the door thus preventing the door from shutting fully.

Else-ways the door seal could have come loose or been split.

Check the door seal and also check for any cracks, a build-up of limescale or other debris, or any tracts in which the seal might have separated from the door.

Removing the seal and allowing it a good wash might improve the situation in some cases or you might need to purchase a new gasket and replace it.

Water Inlet Valve (Solenoid Fill Valve)

The water inlet valve can also be a commonplace issue. This is generally located on the underbelly of the machine which means you will need to take off the kick plate and could need to remove the door cover.

The inlet valve opens and closes to allow water into the machine at different times during the cycle. The fill valve might be leaking, shown by a slight drip, or it may be damaged thus not functioning correctly while the dishwasher is running.

If the water inlet valve fails to close fully this can result in the dishwasher overfilling and cause a leakage.

Usually these valves are not able to be fixed unless it is just the rubber seal that is faulty, thus the whole part would need to be replaced.

Leaking Hoses

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

Two issues can arise when it comes to hoses.

  2. The alternative problem than can easily develop over time is that hoses can be damaged or cracked.

If you are able to determine that the leakage is a result of a faulty hose this should be relatively easy to replace and new hoses are easy to procure.

Pumps and Seals

You are able to visually investigate the rubber seals surrounding the water pumps or motor to ascertain if there is a leak and also replace them if there is.

The Float Switch

The float itself or the float switch might be not working correctly causing the dishwasher to overfill.

A working float will lift up as the water level goes up until it reaches the maximum fill level. The end piece of the float will then activate the switch. If something is blocking this or the float is broken this could be your issues.

Checking the switch will require a multi-meter although it might be obviously damaged in which case getting a new one should stop the leak.

Other Parts that Might Lead to a Leak

A broken wash arm or support may causing leakage. This can also often result in your dishes not being cleaned as effectively as they should.

Broken or faulty lines could likewise cause this fault as may a cracked pump cover if your dishwasher has one.

The motor shaft seal might have cracked causing a leak. This generally presents as a leak coming from the underside of the appliance.

  3. Take photos at each step. This could assist you to reverse the process, describe the component you need in a shop, as well as explain the fault to a repair person if required.
  4. Stay safe. Water and electricity are not good friends so turn off the power first.
  5. If in doubt get in a professional.

The Next Steps You Should Take If Your Initial Investigation Fails to Identify or Resolve the Leak
