Standing water in your machine could have any number of of causes a few of which are easy to resolve. So, before you call a dishwasher repair service here is a list of probable things you may identify on your own. A number of which are not even related to the dishwasher itself.
If you’re fortunate the standing water you have discovered may not be an issue at all. Instead, the program could have been stopped mid-way.
The program may have been interrupted for multiple of reasons. Children pushing buttons, mistakenly leaning on the control panel, a power cut or opening the dishwasher mid-cycle might all prevent the cycle from completing and mean your dishwasher doesn’t empty.
If you suspect this might be the circumstance, or you just want to be sure it’s not the issue start the machine again on a quick cycle.
A proportion appliances might have an empty program meaning it’s worth checking your instruction manual or checking online to find out.
If you have a garbage disposal inspect this before you move on as a blocked waste disposal will prevent the machine from emptying. Run the disposal with plenty of water to make sure there are no obstructions.
If you do find a blockage drain cleaner or a natural alternative can be used to remove the blockage and so this could rectify the issue.
If you sink is draining slowly this may suggest an issue with the plumbing as opposed to an error with your machine.
If the kitchen sink is draining slowly you could try putting a little bicarbonate of soda and white vinegar down the drain, leaving it for a few minutes and subsequently flushing it away with hot water.
A sink plunger might also be used to try and remove the blockage.
This may be all you need to do to let the machine to empty so run a short rinse and drain program now. If not you may manually empty the dishwasher using a jug and a sponge and troubleshoot a few more possible issues.
Make sure you turn off the dishwasher to prevent electrocution.
If while you are carrying out one of these examinations you suspect you may have found and solved the issue you don’t need to go through the rest of the steps. Just start an empty program to check your machine is repaired.
Any number of things could block the filters including corn kernels, labels from tupperware, plastic film covers and smashed glass. Clear glass can also be hard to see if you aren’t looking for it.
Remove the filter and scrub it thoroughly before replacing it. Not all filters are obvious and straightforward to remove so you might need to look at the instruction manual for this.
The next area to check is the waste water hose. Stuck food, a kink in the hose or a crushed hose could all stop your dishwasher from emptying.
Depending on the position of the waste hose (usually the ribbed one) you could have the means to view it by taking off the kick board alternatively you may have to move the dishwasher away from under the counter.
Have a look at the hose in the first instance to find out if it has been squashed or kinked. You may manage manually remove any kinks which should resolve the issue, however, it’s worth noting that when this has occurred it is much more likely to happen again so you might wish to order a replacement hose.
If you can’t see anything you could remove the waste water pipe from the machine and blow into it to figure out if there are any blockages. Be sure to put down newspaper or towels before you remove the hose as even if you have emptied the machine there may still be water in the hose.
If you can’t blow through the pipe this might be the issue.
Remove the hose at the sink end in order to give it a good flush through to clear the obstruction. If you are unable to dislodge the obstruction or the pipe is split or degraded acquire a brand-new one. If you can get rid of the blockage then put the hose back and start a short cycle to double check that you have solved the fault.
You may also examine where the waste hose connects to the sink. This is a typical point for debris to build up so if you happen to take off the waste hose give this point a good clean as well.
You could manually examine the drain valve to make sure it isn’t seized. The drain valve will most often be located in the bottom of the dishwasher on the valve bracket. Examine your instructions if you can’t see it.
Pressing down on the valve or giving it a wiggle will likely be enough to find out if it’s stuck. If you are able to see anything stopping it from moving carefully extract this. If you can’t, this could be when you should call a repair person unless you are undaunted by procuring and swapping out the component on your own.
Your appliance pump makes use of impellers that may become blocked by pieces of china or other debris. Check your pump isn’t blocked by taking off the cover and checking that the impellers can rotate freely.
If it doesn’t sound right your dishwasher pump or motor may be broken and need to be repaired.
If none of the above examinations has solved the fault, or you have reason to believe the pump, pump valve or motor are damaged, it could be the right time to call a plumber.
This way though you will at least be able to give them more information and have prevented having to pay a big call-out charge for a blocked drain.
