Commonplace Causes of Dishwasher Faults as well as How to Mend Them

Some of the most simple causes of dishwasher faults are not really because of a dishwasher fault at all. Before you start getting the tools out as well as watching numerous youtube videos there are a number of problems you can take a look at first.

  1. Check to see whether your dishwasher is level. If your dishwasher isn’t aligned water will easily puddle and spill out even if the dishwasher is working perfectly.
  2. Investigate you have been using the right detergent. You could have seen this with your washing machine. Too much detergent or using the incorrect variety may lead an excess of suds, the suds bubble over and you get a spill.
  3. Investigate your dishwasher door closes correctly. If it does not there may be a blockage, or you may have to replace the hinge or the locking mechanism.
  4. Test the filter at the bottom of the tub for any obvious obstructions because if your dishwasher isn’t draining correctly this can result in overfill and leak.

If you have eliminated these potential problems it’s time to roll up your sleeves and begin a thorough check.

The easiest place to start is the door and test for any obvious issues inside of the machine prior to moving on to the underside. If you can find and so mend the leak without pulling 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 Gasket

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

If the leakage is occasional the problem may be as simple as a big pan or something else pushing against the door and preventing it from shutting properly.

Otherwise the door gasket could have been dislodged or been split.

Inspect the door seal and test for any brittleness, a build-up of limescale or other debris, or any parts in which the gasket might have come away from the door.

Extracting the gasket and giving it a comprehensive wash could improve the situation in some cases or you might have to purchase a new gasket and change it.

Water Inlet Valve (Solenoid Fill Valve)

The water inlet valve can also be a commonplace fault. It is usually situated underneath the machine and so you will need to unscrew the toe board and also could have to take off the door cover.

The fill valve opens and also closes to let water into the dishwasher at various parts of the programme. The inlet valve may be leaking, shown by a slow drip, or it could be broken and so not operating fully during the programme.

In the case that the water inlet valve fails to close correctly this can result in the dishwasher leaking.

Usually water inlet valve cannot be fixed, which means the entire part would have to be changed.

Leaking Hoses

Your dishwasher uses hoses to fill, empty and redistribute water during the cycle.

Two issues might arise with hoses.

  1. The gaskets might go or the connections can work loose meaning it’s a good idea to check all the connection points first.
  2. The other issue than might often develop as you use the machine is that hoses may become damaged or cracked.

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

Pumps and Seals

You can visually investigate the gaskets surrounding the water pumps or motor to determine whether there is a leakage and also change them if there is.

The Float Switch

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

A working float will lift up as the water rises until the optimum or maximum water level is reached. The tail of the float will then operate the switch. If something is blocking this or the float is broken this could be causing your problem.

Testing the switch will require a multi-meter but it might be noticeably damaged in which case replacing it should stop the leak.

Other Parts that May Lead to a Leak

A cracked wash arm or support might resulting in a leak. This could likewise often affect how well your dishes are being cleaned.

Broken or faulty lines might also cause this issue as might a broken pump cap.

The motor shaft seal might have degraded resulting in a leak. This generally presents as a leak coming from the underside of the machine.

Top Tips to Mend Your Machine

  1. Spend less by replacing the gasket rather than the entire part. In most instances, you are able to buy the gasket without the rest of the part which saves time as well as money.
  2. Check the simple solutions first. You don’t need to pull the entire thing away from the wall if it’s the detergent that’s making the problem.
  3. Take pictures at each step. This may make your life easier when you come to reverse the process, explain the part you are looking for in a shop, and also identify the issue to a repair person if required.
  4. Be careful. Water and electricity are not good friends so turn off the power first.
  5. If you’re not sure get in the professionals.

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

If the root of the leakage can’t be discovered the thing you can do is to pull out the dishwasher to get a better look beneath it and also add water to the tub to find out whether the leakage presents itself.

If you are still in the dark your appliance may only show a leakage if the pump is running. In this case, you may wish to hire a qualified technician to pinpoint and mend the problem as there are safety risks of running the dishwasher with electrical elements exposed.
