No-one wants to open their dishwasher and discover standing water but, don’t panic just yet. You could manage rectify the error without having to call a plumber or invest in a new dishwasher.
Your dishwasher declining to empty can have a number of of causes a proportion of which can be simple to rectify. Therefore, before you call a dishwasher repair service try this selection of possible components you could correct yourself. Some of which aren’t even related to the dishwasher itself.
It is probable that there is nothing stopping your dishwasher from emptying. Rather, the cycle may have been stopped mid-way.
The cycle may have been cut short for any number of of reasons. Kids pressing controls, accidentally leaning against the control panel, a power cut or opening the dishwasher mid-program may all prevent the cycle from completing and mean your dishwasher doesn’t drain.
If you think this may be the case, or you just want to be sure it’s not the issue run the machine again on a quick program.
Some machines could have a drain function meaning it’s well worth checking your instruction manual or consulting google to make sure.
If your dishwasher is plumbed into your waste disposal inspect this before you move on as a blocked waste disposal will block your machine from draining. Run the waste disposal with lots of water to make sure there are no blockages.
If you do discover an obstruction drain un-blocker or a plunger may be used to clear the blockage and so this may fix the fault.
If you sink is emptying inefficiently this could signify an issue with the pipes as opposed to an issue with your machine.
If the sink is draining inefficiently you could attempt putting some bicarbonate of soda and vinegar down the plughole, letting it sit for a while, then rinsing it through with hot water.
A plunger might also be employed to try and shift the obstruction.
This could be all you need to do to let your dishwasher to work again so start a quick rinse and empty cycle to check. If this hasn’t sorted the issue you can remove the standing water by hand using a bowl as well as a towel and troubleshoot a few more areas.
At this point make certain to disconnect the machine to avoid electrocution.
If while you are carrying out any of these investigations you think you have found and repaired the issue you don’t have to go through the rest of the issues. Just start an empty cycle to make sure the machine is fixed.
Any number of things could block the filters including popcorn, labels from food jars, plastic film lids and broken glass. Clear plastic lids can also be hard to spot if you don’t look carefully.
Take out the filter and clean it thoroughly before replacing it. Not all filters are obvious and simple to remove so you might need to look at the manual for this.
The next place to examine is the waste pipe. Stuck food, a kink in the hose or a crushed hose could all prevent your machine from draining.
Contingent upon the location of the hose (normally the ribbed one) you may be able to view it simply by taking off the kick board alternatively you could be required to move the dishwasher away from the wall.
Have a look at the pipe first to discover if there are any kinks or it’s been squashed. You might have the means to manually remove any kinks which is likely to deal with the issue, however, it’s worth noting that once this has happened it is much more inclined to happen again so you could need to buy a spare hose.
If you can’t find an issue you may take off the drain pipe from the pump and blow into it to check for any blockages. Be sure to line the floor with newspaper or towels first as there may still be dirty water in the hose.
If you can’t blow through the waste pipe this may be the problem.
Take off the other end of the hose and then give it a thorough clean to get rid of the obstruction. If you can’t remove the obstruction or the waste pipe is cracked or worn invest in a brand-new one. If you may remove the blockage then re-attach the hose and start a short cycle to check that you have repaired the fault.
You can also inspect the point where the pipe connects under your sink. This is a typical spot for debris to build up so if you do take off the waste hose give this connection a good clean as well.
You can manually check the drain valve to check it isn’t got stuck. The drain valve will generally be located in the bottom of the machine on the valve bracket. Check your owners manual if you’re unsure.
Pressing down on the valve or giving it a wiggle will likely be adequate to find out if it’s stuck. If you can see any debris blocking it remove this. If you can’t, this could be a good time to call a plumber unless you are happy in purchasing and replacing the valve on your own.
Your water pump uses impellers that can become obstructed by pieces of china or other debris. Check your pump isn’t blocked by removing the cover and making sure the impellers can be easily rotated.
If it sounds unusual your dishwasher pump or motor could be faulty and need replacing.
If you have been through the above list and the problem remains, or you have reason to believe the pump, pump valve or motor are broken, it might be the right time to call your local repair person.
At least having tried to investigate what is wrong you have avoided having to pay a hefty call-out fee for a blocked drain.
