Simple Explanations of Dishwasher Faults as well as How to Fix Them

Many of the most commonly seen sources of dishwasher faults are not really a result of a broken dishwasher at all. Before you start getting the tools out and also watching numerous online tutorials there are a couple of problems you can troubleshoot first.

  1. Investigate to see if your dishwasher is aligned. If your dishwasher is not level water will quickly puddle and leak regardless of whether or not the dishwasher has a fault.
  2. Test you have been using the correct detergent. You could be aware of this issue with your washer. Too much soap or using the incorrect variety can lead to too many soap suds, the soap suds spill over and so you get a spill.
  3. Test your dishwasher door fully closes. If there’s a gap you might have something obstructing it such as a large plate, or you could need to fix the door fixings.
  4. Test the filter located at the bottom of the tub for any visible obstructions as if your dishwasher isn’t draining correctly this will cause it to overfill and spill.

If none of the above issues apply it’s time to roll up your sleeves and really begin the inspection.

The easiest place to start is the door as well as investigate for any obvious issues within of the machine before you move on to the underneath. If you can find and so fix the issue without pulling out the dishwasher so much the better.

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

Door Seal

The most usual place for a dishwasher to leak is around the door, luckily it is likewise one of the easiest problems to resolve.

If the leak is intermittent the problem may be as easy as an oversized dish or another object pushing against the door thus stopping the door from shutting correctly.

On the other hand the door gasket might have come loose or got split.

Check the door seal and also check for any degradation, mineral deposits or other gunk, or any areas where the gasket has come away from the door.

Removing the gasket and also allowing it a good wash might improve the situation in some instances or you might need to acquire a new gasket and change it.

Water Inlet Valve (Solenoid Fill Valve)

The inlet valve can also be a common problem. The inlet is in most cases found under the machine therefore you may need to remove the toe board and may have to remove the door cover.

The water inlet valve opens and also closes to allow water into the dishwasher at different parts of the cycle. The water inlet valve may be damaged, evidenced with a slight drip, or it may be broken and so not operating properly during the cycle.

In the case that the inlet valve doesn’t shut properly this can lead to the dishwasher overfilling and result in a leak.

Generally water inlet valve are not able to be fixed unless it is only the rubber seal that is faulty, and so the entire valve would have to be changed.

Leaking Hoses

Your dishwasher uses hoses to supply, drain as well as redistribute water within the cycle.

Two issues might arise where hoses are concerned.

  1. The gaskets may break or the contact points can work loose thus it’s a good idea to check all the connections first.
  2. The other problem than can easily develop as time goes by is that hoses can get degraded or get a hole in.

Luckily damaged hoses are relatively simple to procure as well as change, even for a novice.

Pumps and Gaskets

You are able to visually investigate the rubber seals around the pumps or motor to see whether there is a leakage and also replace them if that’s the case.

The Float Switch

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

When operating correctly the float will go up as the water level goes up until it reaches the desired fill level. The tail of the float should then turn on the switch. A blockage or breakage could be causing your problem.

Testing the switch would need a multi-meter but it might be obviously damaged in which case getting a new one should resolve the leak.

Alternative Parts that Might Cause Leakage

A damaged wash arm or support might build up pressure resulting in leakage. This will also often result in your dishes not being cleaned as effectively as they should.

Broken or cracked tubes may also result in this fault as might a damaged pump cover if your dishwasher has one.

The motor shaft gasket could have degraded causing a leak. This will generally show as a puddle coming from underneath the dishwasher.

Top Tips to Fix Your Dishwasher

  1. Spend less by replacing the gasket rather than the entire component. In many situations, you are able to purchase the seal separately which saves you having to change the whole part.
  2. Check the easy solutions before you get more complicated. There’s no point pulling the entire thing away from the wall if the problem is the detergent.
  3. Photograph your progress. This may assist you to put the thing back together, show the part you are looking for to a sales person, as well as explain the issue to a repair person if required.
  4. Be careful. Water and electricity are not good friends so unplug the machine first.
  5. If in doubt get in a repair person.

The Next Steps You Should Take If Your Trouble Shooting Fails to Identify or Resolve the Leak

If the root of the leak can’t be discovered the thing you might do is to pull the dishwasher away from the wall to get better access underneath it and also add water to the tub to find out whether the leak becomes visible.

If you are still in the dark your appliance might only show a leakage if during a cycle. In this case, you should employ a qualified technician to pinpoint and also resolve the leak as there are safety risks of running the dishwasher with electrical elements uncovered.
