Why is My Dishwasher Not Draining?

No-one is happy to open their dishwasher and discover standing water but, don’t lose it just yet. You could manage figure out the error without having to call a repair person or buy a new dishwasher.

Standing water in your machine may be caused by multiple things a proportion of which are simple to deal with. So, before you call a dishwasher repair service here is a lineup of possible things you could troubleshoot yourself. Some of which aren’t even related to the machine itself.

Check the program wasn’t cut short

It is possible that there is nothing stopping your dishwasher from draining. Instead, the cycle may have been stopped mid-way.

The program could have been cut short for a number of of reasons. Children pushing controls, accidentally leaning on the buttons, a power cut or opening the dishwasher mid-program may all interrupt the cycle and mean your dishwasher doesn’t drain.

If you think this may be the situation, or you think it might be a good idea to check start your dishwasher again on a short program.

Some appliances might have an empty program meaning it’s worthwhile checking your manual or consulting google to make sure.

Check the disposal

If your dishwasher is attached to the waste disposal examine this first as an obstructed waste disposal will block your machine from emptying. Turn on the garbage disposal using lots of water to make sure there are no issues.

If you do find an issue drain cleaner or a plunger could be employed to remove the obstruction and so this may deal with the fault.

Examine the sink waste for issues

If you kitchen sink is emptying inefficiently this could suggest an issue with the pipes instead of a problem with your dishwasher.

If the sink is draining inefficiently you can try putting some bicarb and vinegar down the drain, letting it sit for a few minutes and then flushing it away with boiling water.

A sink plunger could also be utilized to try and shift the obstruction.

This might be enough to allow the dishwasher to empty so start a quick cycle at this point. If not you could remove the water by hand using a bowl and also a towel and check the next few possible issues.

At this point make sure you turn off the machine to avoid electrocution.

If while you are carrying out one of these examinations you suspect you may have found and fixed the problem there is no need to continue to the next issue. Just start an empty program to check your machine is repaired.

Examine and rinse the filters

Corn Kernels, paper from tupperware, film lids and broken glass, plus food debris, may all obstruct the machine filter. Clear glass can also be difficult to spot if you aren’t looking for it.

Take out the filter and clean it thoroughly before replacing it. Not all filters are obvious and simple to remove so you could need to refer to the instruction manual for this.

Is the waste pipe blocked?

The next place to check is the waste water pipe. Many things could cause an obstruction including a build up of food debris, a kink in the hose, or a crushed hose. All of which may all impede your dishwasher from emptying.

Contingent upon the position of the waste pipe (normally the corrugated one) you may have the means to inspect it by lifting away the kick board or you may be required to move the machine out from under the counter.

Look at the pipe first to find out if it has been squashed or kinked. You could manage manually remove any kinks which is likely to solve the issue, but it’s worth noting that once this has occurred the probability of it happening again is greatly increased so you might wish to buy a spare hose.

If you can’t find anything you could disconnect the waste pipe from the dishwasher and blow through it to check for any blockages. Make sure you put down newspaper or towels before you remove the hose as there might still be waste water in the pipe.

If you can’t blow through the waste hose this could be the problem.

Disconnect the hose at the sink end in order to give it a good clean to get rid of the obstruction. If you are unable to get rid of the blockage or the hose is split or worn purchase a new one. If you can get rid of the obstruction then replace the hose and start a short program to check that you have repaired the error.

You could also inspect the point where the hose attaches to the sink as well. This is a typical point for a build-up of gunk so if you do take off the waste pipe give this connection a thorough scrub as well.

Check the drain valve

You may manually examine the drain valve to make sure it isn’t got stuck. The drain valve will most often be found at the base of the machine on the valve bracket. Check your manual if you’re unsure.

Depressing the valve or wiggling it a bit will likely be adequate to let you know if it’s stuck. If you are able to see any debris blocking it carefully extract this. If you are unable to, this may be when you should ring a plumber unless you are undaunted by purchasing and repairing the valve yourself.

Check your pump is not blocked

Your appliance pump makes use of impellers that could become obstructed by pieces of glass or other debris. Check your impellers aren’t broken by taking off the cover and making sure the impellers can be easily rotated.

Run your dishwasher and listen for any unusual noises

If your dishwasher doesn’t sound right your pump or motor might be broken and need to be repaired.

Call a repair person

If none of the above investigations has solved the issue, or you suspect the pump, pump valve or motor are not working, it may be time to call for help.

At least having done your best to troubleshoot you have managed to avoid having to pay a hefty call-out charge for a blocked hose.
