No-one wishes to open their dishwasher and discover it hasn’t drained fully but, try not to overreact just yet. You could have the means to rectify the fault without having to call a plumber or acquire a brand-new dishwasher.
Standing water in your dishwasher could be caused by a number of things a few of which can be straightforward to solve. Therefore, in advance of calling a dishwasher repair service try this list of probable things you can identify by yourself. A proportion of which are not even a fault of the dishwasher itself.
If you’re fortunate the standing water you have discovered may not be a fault at all. Alternatively, the program might have been cut short.
The cycle might have been interrupted for any number of of reasons. Children pressing buttons, accidentally pushing on the buttons, a power outage or opening the dishwasher mid-cycle could all prevent the cycle from completing and mean your dishwasher doesn’t empty.
If you believe this might be the situation, or you just want to be sure it’s not the issue run the dishwasher again on a short cycle.
A number machines might have an empty function meaning it’s well worth consulting your manual or checking online to make sure.
If your dishwasher is attached to a garbage disposal inspect this before you do anything else as a blocked waste disposal will stop your dishwasher from draining. Turn on the waste disposal with lots of water to ensure there are no obstructions.
If you do find an issue drain cleaner or a natural alternative can be employed to remove the obstruction and this could resolve the fault.
If you sink is emptying reluctantly this might signify a plumbing issue as opposed to an issue with your dishwasher.
In the case that the sink is draining slowly you could attempt putting a little bicarbonate of soda and white vinegar down the drain, leaving it for a while, then flushing it away with boiling water.
A sink plunger could also be utilized to try and shift the blockage.
This may be all you need to do to allow your machine to empty so run a short rinse and empty cycle to check. If this hasn’t solved the problem you could remove the dirty water by hand using a bowl and also a sponge and check the next few possible issues.
At this point make certain to turn off the machine to stay safe.
If in the process of one of these investigations you suspect you have detected and fixed the problem there is no need to continue to the next step. Just complete an empty program to make sure your machine is fixed.
Corn Kernels, labels from jars, plastic covers and smashed glass, plus food debris, could all block the machine filter. Clear film may also be difficult to see if you don’t look carefully.
Take out the filter then give it a thorough wash before replacing it. Not all filters are obvious and simple to remove so you might need to consult the instructions for this.
The next area to inspect is the waste water hose. Stuck food, a kink in the hose or a crushed hose can all impede your dishwasher from emptying.
Contingent upon the position of the hose (normally the ribbed one) you could be able to look at it by means of taking off the kick board alternatively you could be required to move the machine out from under the counter.
Look at the pipe first to find out if it has been crushed or kinked. You may be able to fix these issues by hand which should resolve the issue, but it’s worth noting that once this has occurred it is much more inclined to happen again so you could need to buy a replacement hose.
If you are unable to see any obvious kinks or obstructions you could disconnect the waste pipe from the dishwasher and blow through it to discover any blockages. Be sure to put down newspaper or towels before you remove the hose as even if you have emptied the dishwasher there could still be water in the hose.
If you are unable to blow through the hose this might be the issue.
Remove the other end of the hose and then give it a thorough flush through to remove the obstruction. If you can’t get rid of the blockage or the waste hose is slit or degraded buy a new one. If you could remove the obstruction then re-attach the hose and start a short cycle to make sure you have repaired the fault.
You could also inspect the point where the hose connects under your sink. This is a typical spot for blockages to occur so if you happen to take off the hose give this point a thorough scrub as well.
You can check the drain valve by hand to make sure it hasn’t stopped working. The drain valve will generally be situated at the base of the dishwasher on the valve bracket. Examine your instruction manual if you can’t see it.
Depressing the valve or giving it a wiggle should be adequate to let you know if it’s seized. If you can see anything stopping it from moving get rid of this. If you can’t, this could be a good time to call a plumber unless you are undaunted by ordering and swapping out the valve on your own.
Your water pump uses impellers that may be blocked by broken china or other debris. Check your impellers aren’t obstructed by taking off the cover and making sure the impellers can rotate freely.
If it is making funny noises your pump or motor may be broken and need replacing.
If you have been through the above list and the error remains, or you suspect the pump, pump valve or motor are damaged, it could be time to get the professionals.
At least having done your best to investigate what is wrong you have managed to avoid needing to pay a big call-out fee for a blocked drain.
