No-one wishes to open their machine and discover it hasn’t emptied correctly but, try not to panic just yet. You might manage rectify the error before you have to call a repair person or purchase a brand-new machine.
Your machine declining to drain may be caused by multiple components some of which are simple to rectify. So, before you call a dishwasher repair service try this selection of probable issues you could correct by yourself. A proportion of which are not even related to the machine itself.
If you’re fortunate the standing water you have discovered may not be a problem at all. Rather, the cycle could have been stopped mid-way.
The cycle may have been cut short for a number of of reasons. Little fingers pressing controls, accidentally leaning on the controls, a power outage or opening the dishwasher mid-program might all interrupt the cycle and mean your machine doesn’t empty.
If you suspect this may be the case, or you feel it could be a good idea to check start your machine again on a quick cycle.
A few machines could have a drain cycle meaning it’s worth checking your instructions or consulting google to find out.
If you have a garbage disposal inspect this before you do anything else as an obstructed disposal will stop the machine from emptying. Turn on the waste disposal with plenty of water to check there are no blockages.
If you do find an obstruction drain unclogger or a natural alternative could be used to unclog the blockage and this might rectify the issue.
If you kitchen sink is draining reluctantly this could suggest an issue with the pipes as opposed to an error with your machine.
If the kitchen sink is draining inefficiently you may attempt putting a little bicarbonate of soda and white vinegar down the drain, letting it sit for a few minutes and subsequently washing it through with boiling water.
A plunger may also be used to attempt to remove the obstruction.
This could be enough to allow your dishwasher to empty so start a short cycle now. If not you could manually remove the standing water using a bowl and a towel and troubleshoot a few more possible issues.
At this point make certain to disconnect the dishwasher to stay safe.
If during any one of these investigations you believe you may have found and fixed the error you don’t need to go through the rest of the steps. Just complete an empty cycle to make sure your dishwasher is once again emptying as it used to.
Any number of things could block the filters including corn kernels, paper from food jars, plastic covers and smashed glass. Clear film may also be difficult to spot if you aren’t looking for it.
Take out the filter and give it a good scrub before putting it back in place. Not all machines have their filter in the same place so you may need to look at the instructions for this.
The next component to inspect is the drain pipe. Many things could cause a blockage including a build up of food debris, a kink in the hose, or a crushed hose. All of which can all stop your machine from emptying.
Depending on the location of the waste pipe (normally the corrugated one) you could have the means to look at it by taking off the base alternatively you may have to move the machine away from the wall.
Look at the pipe first to discover if it has been crushed or kinked. You could manage manually remove any kinks which should resolve the issue, but be aware that once this has occurred it is significantly more likely to happen again so you might wish to order a spare hose.
If you can’t see anything you can remove the waste water pipe from the machine and blow through it to discover any blockages. Make sure you put down newspaper or towels before you remove the hose as even if you have emptied the dishwasher there could still be waste water in the hose.
If you can’t blow through the waste pipe this could be the problem.
Take off the other end of the hose and give it a thorough flush through to clear the blockage. If you can’t dislodge the blockage or the hose is cracked or degraded acquire a brand-new one. If you can get rid of the blockage then put the hose back and start a quick cycle to double check that you have fixed the error.
You may also examine where the pipe attaches under your sink. This is a likely point for a build-up of gunk so if you do take off the pipe give this point a thorough clean as well.
You can inspect the drain valve by hand to check it hasn’t got stuck. The drain valve will usually be found in the bottom of the dishwasher on the valve bracket. Examine your instructions if you’re not sure.
Depressing the valve or giving it a jiggle should be enough to let you know if it’s stuck. If you can see something stopping it from moving get rid of this. If you are unable to, this might be when you should ring a plumber unless you are undaunted by purchasing and repairing the part yourself.
Your appliance pump uses impellers that can get blocked by broken glass or other debris. Check your pump isn’t blocked by removing the safety cover and making sure the impellers can be easily rotated.
If your dishwasher sounds unusual your pump or motor might be damaged and need to be repaired.
If you have been through the above list and the problem persists, or you think the pump, pump valve or motor are not working, it may be the right time to call your local repair person.
This way though you will at least manage give them more information and have prevented having to pay a hefty repair charge for a blocked hose.
