Commonplace Sources of Dishwasher Leaks and How to Resolve Them

A lot of the more simple sources of dishwasher faults aren’t really due to a broken dishwasher at all. Before you start getting the tools out as well as watching numerous youtube videos there are a couple of problems you can take a look at first.

  1. Test to find out whether your dishwasher is level. If your dishwasher is misaligned water can easily puddle and so spill out regardless of whether or not the dishwasher has a fault.
  2. Test you have been using the right detergent. You might be familiar with this fault with your washer. An excess of soap or using the incorrect type could result in to too many suds, the suds spill over resulting in a leak.
  3. Check your dishwasher door fully closes. If it doesn’t there may be an obstruction, or you might have to adjust the door fixings.
  4. Test the filter at the base of the machine for any easy to see obstructions because if your dishwasher isn’t draining properly this is likely to cause it to overfill and so leak.

When you have looked at these possible causes it’s time to get ready and really start the inspection.

The easiest place to start is the door and investigate for any visible damage inside of the machine before you move on to the underneath. If you can identify and so resolve the problem before you have to pull out the dishwasher you’ll save yourself a lot of hassle.

Also make sure you disconnect the appliance first by either unplugging it or turning off the circuit breaker for the dishwasher.

Door Seal

The most common place for a dishwasher to leak is around the door, fortunately it is also one of the quickest issues to solve.

If the leakage is periodic the problem could be as straightforward as a large plate or another object pushing against the door thus preventing it from shutting correctly.

On the other hand the door seal might have been dislodged or become split.

Inspect the door gasket and also check for any brittleness, a build-up of limescale or other debris, or any tracts where the gasket has come away from the door.

Removing the gasket and also allowing it a good clean could improve the situation in some cases or you may be required to purchase a new seal and change it.

Water Inlet Valve (Solenoid Fill Valve)

The inlet valve can also be a simple issue. The inlet is in most cases situated on the underbelly of the machine so you will have to take off the kick plate and also could have to remove the door cover.

The inlet valve opens and closes to allow water into the machine at various parts of the programme. The water inlet valve could be damaged, evidenced by a slow drip, or it may be damaged thus not functioning properly while the dishwasher is running.

If the fill valve doesn’t close fully this can mean that the dishwasher overfills, causing a leak.

In General inlet valve can’t be refurbished, which means the whole valve would need to be changed.

Leaking Hoses

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

Two complications may develop where hoses are concerned.

  1. The gaskets can get damaged or the connections could come loose thus it’s worth having a look at all the connection points first.
  2. The other fault than might easily develop as you use the machine is that hoses could become damaged or cracked.

If you are able to determine that the leak is coming from a hose this will be simple to change and spare hoses are easy to come by.

Pumps and Gaskets

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

The Float Switch

Either the float or the float switch may be faulty resulting in the dishwasher overfilling.

When working correctly the float will rise as the water rises until it reaches the desired fill level. The tail of the float would then turn on the switch. A blockage or breakage could be causing your issues.

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

Other Parts that Might Lead to Leakage

A damaged wash arm or support can resulting in a leak. This will likewise often result in your dishes not being cleaned as effectively as they should.

Broken or faulty tubes can also result in this fault as can a broken pump cap.

The motor shaft gasket might have come loose resulting in leakage. This generally presents as leakage coming from the underside of the machine.

Top Tips to Sort Out Your Dishwasher

  1. Spend less by changing the seal instead of the whole component. In most situations, you can buy the gasket separately which saves you having to replace the whole part.
  2. Test the simple fixes before you get more complicated. There’s no point pulling the entire machine away from the wall if it’s the soap that’s making the issue.
  3. Photograph your progress. This could make your life easier when you come to reverse the process, describe the component you are looking for in a shop, and identify the fault to an engineer if needed.
  4. Stay safe. Water and electricity do not mix so turn off the power first.
  5. If you’re struggling call the professionals.

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

If the root of the leakage can’t be uncovered the next step you might take is to pull out the machine to get a clearer view of the underneath it and add water to the tub to see whether the leakage becomes visible.

If you are still in the dark your dishwasher might only show a leakage when during a cycle. In this case, you may wish to employ a appliance repair person to determine and also fix the problem due to the safety risks of running the dishwasher with electrical components exposed.
