Why is My Dishwasher Not Draining?

Although it’s never a welcome sight to open your dishwasher and discover the machine hasn’t emptied fully, try not to lose it just yet. You may manage deal with the error without having to call a repair person or acquire a new machine.

Your dishwasher declining to drain can be induced by a number of things a few of which can be simple to fix. Therefore, in advance of calling a dishwasher repair service try this selection of potential issues you could troubleshoot yourself. A number of which aren’t even related to the machine itself.

Check the cycle wasn’t stopped mid-way

It is probable that there is nothing stopping your dishwasher from draining. Alternatively, the cycle could have been cut short.

The program might have been cut short for a number of of reasons. Little fingers pushing controls, mistakenly leaning against the control panel, a power outage or opening the machine mid-cycle might all interrupt the program and mean your dishwasher doesn’t empty.

If you think this could be the case, or you feel it could be worthwhile checking run your dishwasher again on a quick cycle.

A proportion appliances may have an empty cycle so it’s well worth having a look at your manual or checking online to check.

Check the disposal

If you have a disposal inspect this before you do anything else as a blocked disposal will block the dishwasher from draining. Turn on the disposal with fast running water to check there are no blockages.

If you do discover an obstruction drain un-blocker or a plunger may be employed to clear the obstruction and so this may rectify the fault.

Check the sink waste for clogs

If you kitchen sink is emptying reluctantly this may signify an issue with the drains as opposed to a fault with your dishwasher.

In the case that the kitchen sink is emptying slowly you can try putting a little bicarbonate of soda and white vinegar down the drain, leaving it for a while and then washing it away with hot water.

A plunger may also be employed to attempt to shift the blockage.

This may be enough to allow your dishwasher to work again so run a quick rinse and empty program now. If this hasn’t solved the problem you may remove the dirty water by hand using a bowl and also a towel and troubleshoot a few more areas.

At this point make certain to turn off the machine to stay safe.

If in the process of any one of these examinations you suspect you have detected and solved the fault you don’t have to go through the rest of the steps. Just run an empty cycle to make sure your dishwasher is now emptying as it used to.

Inspect and clean the filters

Any number of things could block the filters including popcorn, paper from jars, plastic covers and broken glass. Clear film could also be difficult to see if you aren’t looking for it.

Remove the filter then give it a thorough wash before putting it back in place. Not all dishwashers have their filter in the same location so you could need to consult the instruction manual for this.

Is the drain hose obstructed?

The next component to examine 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 draining.

Depending on the position of the waste pipe (usually the ribbed one) you could manage look at it by lifting away the kick board alternatively you might be required to move the dishwasher away from the wall.

Have a look at the hose first to find out if it has been squashed or kinked. You could be able to manually straighten out any kinks which will most likely solve the issue, but it’s worth noting that when this has happened the probability of it happening again is massively increased so you may need to order a new hose.

If you are unable to find any obvious kinks or obstructions you could remove the waste water hose from the machine and blow into it to figure out if there are any blockages. Be sure to put down newspaper or towels first as there might still be waste water in the hose.

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

Remove the hose at the sink end and give it a thorough flush through to remove the blockage. If you are unable to shift the obstruction or the pipe is cracked or degraded acquire a brand-new one. If you could get rid of the blockage then put the hose back and run a short program to make sure you have solved the error.

You can also check where the pipe connects to the sink. This is a likely spot for a build-up of gunk so if you do take off the waste hose give this connection a thorough clean as well.

Inspect the drain valve

You may manually examine the drain valve to make sure it isn’t got stuck. The drain valve will often be situated at the base of the dishwasher on the valve bracket. Consult your owners manual if you’re not sure.

Depressing the valve or giving it a wiggle should be enough to let you know if it’s stuck. If you can see an object stopping it from moving get rid of this. If you are unable to, this might be when you should call a repair person unless you are undaunted by purchasing and replacing the component on your own.

Check your pump is not blocked

Your dishwasher pump makes use of impellers that could get blocked by pieces of glass or other objects. Check your pump isn’t broken by taking off the safety cover and checking that the impellers are free to move.

Run your dishwasher and listen for any unusual sounds

If the dishwasher is making funny noises your dishwasher pump or motor might be damaged and need to be repaired.

Call a repair person

If none of the above examinations has fixed the problem, or you have reason to believe the pump, pump valve or motor are damaged, it may be the right time to get the professionals.

This way though you will at least manage give them more information and have prevented having to pay a hefty repair fee for a blocked hose.
