Commonplace Explanations of Dishwasher Faults and How to Fix Them

Some of the most commonly seen explanations of dishwasher leaks aren’t actually because of a broken dishwasher at all. Prior to starting getting the tools out and also looking at numerous youtube tutorials there are a couple of problems you might want to take a look at first.

  1. Investigate to see whether your dishwasher is level. If your dishwasher is misaligned water can easily puddle and spill out regardless of whether or not the dishwasher has a fault.
  2. Check you are using the right soap. You might be aware of this fault with your washer. An excess of detergent or using the incorrect variety may lead to too many soap suds, the suds bubble over resulting in a leak.
  3. Test your dishwasher door closes correctly. If there’s a gap there may be an obstruction, or you might need to replace the door fixings.
  4. Check the filter located at the base of the tub for any obvious drainage issues as if your dishwasher isn’t emptying effectively this is likely to cause it to overfill and spill.

If none of the above issues apply it’s time to get ready and really start a thorough check.

To make your life easier start with the door and check for any obvious issues inside of the machine prior to moving on to the underside. If you are able to identify as well as fix the issue without pulling out the dishwasher you’ll save yourself a lot of hassle.

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

Door Seal

The door is no doubt the most common place for leakage as well as one of the quickest issues to fix.

If the leak is periodic the issue may be as simple as a large plate or something else pushing against the door thus stopping the door from closing fully.

Otherwise the door seal could have come out of place or been split.

Examine the door gasket and test for any cracks, a build-up of limescale or other gunk, or any parts in which the seal has come away from the door.

Taking off the seal and also allowing it a comprehensive wash has been known to help in some cases or you might need to buy a new gasket and replace it.

Water Inlet Valve (Solenoid Fill Valve)

The water inlet valve can also be a simple fault. It is usually situated underneath the machine therefore you may need to remove the toe board and also could need to take off the door cover.

The fill valve opens and closes to allow water into the dishwasher at different parts of the programme. The water inlet valve could be leaking, shown with a slow drip, or it might be broken and so not functioning properly while the dishwasher is running.

If the fill valve fails to close correctly this can result in the dishwasher overfilling and cause a leakage.

Often these valves cannot be refurbished unless it is just the rubber gasket that is faulty, which means the entire valve would need to be changed.

Leaking Hoses

Hoses are needed to supply, empty and also redistribute water during the programme.

Two issues can present themselves with hoses.

  1. The gaskets may get damaged or the connections can come loose meaning it’s a good idea to check all the connections first.
  2. The alternative problem than can easily develop as you use the machine is that hoses could be degraded or cracked.

If you can see that the leakage is a result of a faulty hose this will be simple to replace and spare hoses are easy to procure.

Pumps and Seals

You can visually investigate the rubber gaskets that are part of the pumps or motor to see if there is a leakage and replace them if there is.

The Float Switch

The float itself or the float switch might be not working correctly resulting in the dishwasher overfilling.

When working correctly the float will go up as the water rises until the optimum or highest water level is attained. The end piece of the float would then turn on the switch. A blockage or breakage could be causing your problem.

Checking the switch will require a multi-meter but it may be clearly broken in which case getting a new one should stop the leak.

Alternative Parts that Could Lead to a Leak

A broken wash arm or support could causing a leak. This will likewise often result in your dishes not being cleaned as effectively as they should.

Broken or damaged lines can likewise result in this issue as might a broken pump cover if your machine has one.

The motor shaft gasket may have come loose causing a leak. This will generally show as a puddle coming from underneath the appliance.

Top Tips to Fix Your Dishwasher

  1. Spend less by checking the seal rather than the entire part. In many cases, you are able to buy the gasket without the rest of the part which saves you having to replace the entire part.
  2. Check the quick fixes before you get more complicated. There’s no point pulling the whole thing away from the wall if it’s the soap that’s causing the issue.
  3. Take pictures at each step. This may make your life easier when you come to reverse the process, describe the part you need to a sales person, as well as identify the problem to a repair person if needed.
  4. Stay safe. Water and electricity are not good friends so unplug the machine first.
  5. If you’re struggling get in the professionals.

The Next Steps You Should Take If Your Trouble Shooting Doesn’t Identify or Fix the Leak

If the cause of the leakage can’t be discovered the thing you could do is to pull the machine away from the wall to get better access underneath it and add water to the tub to see whether the leakage presents itself.

If you are still in the dark your appliance might only show a leakage when it’s running. If this is the case, you should get a service engineer to diagnose and also resolve the leak due to the safety risks of running the dishwasher with electrical parts uncovered.
