No-one is happy to open their dishwasher and discover it hasn’t emptied fully but, don’t overreact just yet. You might manage rectify the issue before you have to call a plumber or acquire a new dishwasher.
Your dishwasher declining to empty can have a number of of causes a few of which are straightforward to solve. Therefore, before you call a dishwasher repair service try this selection of probable things you may troubleshoot on your own. A number of which are not even a fault of the machine itself.
If you’re fortunate the fact your dishwasher hasn’t emptied may not be an issue at all. Rather, the cycle may have been stopped mid-way.
The program could have been cut short for a number of of reasons. Little fingers pushing controls, inadvertently pressing on the control panel, a power outage or opening the dishwasher mid-cycle might all interrupt the cycle and mean your dishwasher doesn’t empty.
If you suspect this may be the case, or you just want to be sure it’s not the issue start your machine again on a short program.
A number dishwashers might have an empty program so it’s worthwhile consulting your manual or checking online to check.
If your dishwasher is connected to your disposal inspect this first as an obstructed waste disposal will block your dishwasher from emptying. Run the garbage disposal with fast running water to make sure there are no obstructions.
If you do uncover an obstruction drain unclogger or a natural alternative may be sought after to clear the obstruction and this may deal with the error.
If you sink is draining inefficiently this may signify a plumbing issue rather than an issue with your machine.
If the sink is emptying slowly you could try putting some bicarb and vinegar down the plughole, letting it sit for a few minutes and subsequently washing it through with boiling water.
A sink plunger could also be employed to attempt to dislodge the obstruction.
This could be all you need to do to allow your machine to empty so run a short rinse and drain program now. If not you may remove the dirty water by hand using a bowl and also a towel and have a look at a few more likely causes.
At this point make sure you turn off the machine to avoid electrocution.
If in the process of any of these examinations you think you may have detected and solved the fault there is no need to continue to the next step. Just run an empty program to make sure your machine is now emptying as it should.
Any number of things could block the filters including corn kernels, paper from food jars, film lids and broken glass. Clear plastic lids could also be hard to see if you aren’t looking for it.
Take out the filter then give it a thorough scrub before replacing it. Not all dishwashers have their filter in the same location so you may need to refer to the instructions for this.
The next place to examine 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 draining.
Subject to the position of the waste pipe (usually the corrugated one) you may manage look at it by means of removing the base alternatively you could need to pull the machine away from under the counter.
Have a look at the hose first to see if it has been crushed or kinked. You could have the means to manually fix any kinks which should deal with the issue, but be aware that once this has happened it is much more inclined to happen again so you may wish to purchase a new hose.
If you are unable to see anything you can take off the drain pipe from the machine and blow into it to figure out if there are any blockages. Be sure to line the floor with newspaper or towels first as there may still be waste water in the pipe.
If you can’t blow through the waste hose this might be the issue.
Take off the hose at the sink end and give it a thorough clean to get rid of the blockage. If you are unable to get rid of the obstruction or the waste pipe is split or damaged invest in a new one. If you can get rid of the blockage then put the hose back and start a short program to make sure you have repaired the problem.
You could also examinethe point where the hose attaches under your sink as well. This is a common place for debris to build up so if you happen to remove the waste pipe give this connection a good clean as well.
You may manually inspect the drain valve to ensure it hasn’t seized. The drain valve will usually be located in the bottom of the machine on the valve bracket. Consult your manual if you’re unsure.
Depressing the valve or giving it a wiggle will likely be sufficient to find out if it’s stuck. If you can see an object stopping it from moving get rid of this. If you can’t, this might be the right time to get in touch with a repair person unless you are undaunted by ordering and repairing the part on your own.
Your appliance pump makes use of impellers that can be blocked by pieces of china or other debris. Check your pump isn’t broken by taking off the cover and checking that the impellers can be easily rotated.
If the dishwasher doesn’t sound right your pump or motor might be damaged and need replacing.
If you have been through the above list and the error remains, or you have reason to believe the pump, pump valve or motor are not working, it might be time to call for help.
This way though you will at least be able to give them more information and have avoided needing to pay a big call-out charge for a blocked drain.
