Everyday Causes of Dishwasher Faults and How to Resolve Them

A lot of the more simple sources of dishwasher faults are not really a result of a broken dishwasher . Before you start preparing yourself for an engineering task and watching numerous youtube tutorials there are a couple of issues you might want to take a look at first.

  1. Test to see if your dishwasher is level. If your dishwasher is wonky water will easily pool as well as spill out without there being anything that needs to be mended or changed.
  2. Test you are using the correct detergent. You may have seen this with your washer. Too much detergent or the wrong type could lead an excess of bubbles, the bubbles spill over and so you get a leak.
  3. Test your dishwasher door fully closes. If it doesn’t you could have an object obstructing it such as a large plate, or you might have to adjust the hinge or the locking mechanism.
  4. Check the filter located in the base of the machine for any easy to see drainage issues as if your dishwasher isn’t draining effectively this will result in overfill and leak.

If you have ruled out these possible causes it’s time to roll up your sleeves and really begin a thorough check.

To make your life easier start with the door as well as test for any obvious damage in the interior of the machine prior to moving on to the underside. If you can find as well as fix the problem before you have to pull out the dishwasher you’ll save yourself a lot of hassle.

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

Door Gasket

The most commonly seen place for a dishwasher to leak is around the door, luckily it is likewise one of the quickest issues to resolve.

If the leak is occasional the issue may be as straightforward as a big pan or something else putting pressure into the door thus preventing it from shutting properly.

On the other hand the door gasket might have come out of place or become damaged.

Check the door gasket and also investigate for any degradation, mineral deposits or other deposits, or any parts in which the gasket might have separated from the door.

Extracting the seal and giving it a comprehensive wash has been known to help in some instances or you might be required to buy a new gasket and replace it.

Water Inlet Valve (Solenoid Fill Valve)

The inlet valve can be a further simple issue. This is generally found underneath the machine which means you will most likely need to unscrew the kick plate and may need to take off the door cover.

The water inlet valve opens and closes to allow water into the tub at various parts of the programme. The water inlet valve could be showing a leak, demonstrated with a slight drip, or it could be damaged thus not functioning properly throughout the cycle.

If the water inlet valve doesn’t shut correctly this can mean that the dishwasher overfills, causing a leak.

Generally these valves are not able to be refurbished unless it is just the rubber seal that is damaged, thus the entire component would have to be changed.

Leaking Hoses

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

Two problems can arise where hoses are the cause.

  1. The seals might break or the contact points might come loose so it’s worth examining all the connections first.
  2. The alternative fault than might easily happen as time goes by is that hoses may get degraded or cracked.

If you are able to see that the leak is a result of a faulty hose this should be relatively easy to replace and replacement hoses are readily available.

Pumps and Gaskets

You can visually investigate the gaskets that are part of the water pumps or motor to determine if there is a leak as well as change them if there is.

The Float Switch

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

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

Checking the switch would need a multi-meter although it may be clearly damaged in which case getting a new one should stop the leak.

Alternative Components that May Lead to Leakage

A cracked wash arm or support may puch water under the door causing leakage. 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 damaged pump cap if your dishwasher has one.

The motor shaft seal may have degraded resulting in leakage. This will generally show as leakage coming from underneath the appliance.

Top Tips to Mend Your Dishwasher

  1. Spend less by checking the gasket rather than the whole part. In many cases, you can buy the gasket separately which saves you having to replace the whole component.
  2. Test the easy fixes first. There’s no point pulling the entire dishwasher away from the wall if it’s the soap that’s causing the leak.
  3. Take photos as you go along. This could assist you to reverse the process, explain the part you need in a shop, as well as identify the fault to an engineer if needed.
  4. Be careful. Water and electricity do not mix so unplug the machine first.
  5. If in doubt get in the professionals.

The Next Steps You Should Take If Your Initial Investigation Doesn’t Identify or Resolve the Leak

If the root of the leakage remains a mystery the next step you may take is to pull out the dishwasher to get a clearer view of the underneath it and also add water to the tub to see whether the leak becomes visible.

If you are still in the dark your dishwasher may only show a leakage when the pump is running. In this instance, you should employ a service engineer to determine and fix the problem due to the safety risks of checking for faults with electrical elements exposed.
