Your machine failing to drain could have multiple of causes a few of which are easy to figure out. Therefore, before you call a dishwasher repair service here is a selection of probable components you may troubleshoot on your own. A number of which aren’t even caused by the dishwasher itself.

Check the program wasn’t cut short

If you’re fortunate the fact your dishwasher hasn’t drained may not be an issue at all. Rather, the cycle may have been cut short.

The cycle may have been interrupted for a number of of reasons. Children pushing controls, mistakenly leaning against the control panel, a power surge or opening the dishwasher mid-program might all interrupt the cycle and mean your machine doesn’t drain.

If you suspect this could be the circumstance, or you just want to be sure it’s not the issue run your machine again on a short program.

Some appliances might have a drain capacity so it’s well worth checking your owners manual or doing a quick internet search to find out.

Check the garbage disposal

If your dishwasher is plumbed into the disposal inspect this before you move on as a blocked waste disposal will block your machine from draining. Run the disposal with lots of water to make sure there are no issues.

If you do uncover an obstruction drain cleaner or a natural alternative may be sought after to unclog the obstruction and so this could deal with the error.

Examine the sink waste for blockages

If you sink is draining reluctantly this may indicate a plumbing issue rather than an error with your dishwasher.

In the case that the kitchen sink is emptying reluctantly you may try putting some bicarbonate of soda and white vinegar down the drain, leaving it for a while and subsequently rinsing it away with boiling water.

A plunger may also be utilized to attempt to shift the obstruction.

This might be sufficient to permit your machine to work again so start a short rinse and drain program now. If not you can remove the water by hand using a bowl as well as a towel and check the next few possible issues.

Make certain to turn off the dishwasher to stay safe.

If during any one of these investigations you think you may have found and repaired the error you don’t have to go through the rest of the steps. Just start an empty cycle to make sure your machine is fixed.

Examine and wash the filters

Any number of things could block the filters including corn kernels, labels from containers, film lids and smashed glass. Clear plastic lids could also be difficult to see if you don’t look closely.

Take out the filter then give it a thorough wash before putting it back in place. Not all filters are obvious and easy to remove so you might need to consult the owners manual for this.

Is the drain hose obstructed?

The next place to check is the waste water pipe. Stuck food, a kink in the hose or a crushed hose could all stop your machine from emptying.

Contingent upon the location of the waste pipe (normally the corrugated one) you could manage inspect it by lifting away the kick plate alternatively you could need to pull the dishwasher away from under the counter.

Visually inspect the hose first to see if it has been squashed or kinked. You might be able to fix these issues by hand which is likely to deal with the issue, but be aware that once this has happened the chance of it happening again is greatly increased so you might need to purchase a spare hose.

If you can’t find any obvious kinks or obstructions you could take off the waste water hose from the dishwasher and blow into it to discover any blockages. Be sure to line the floor with newspaper or towels first as there might still be waste water in the pipe.

If you are unable to blow through the hose this might be the problem.

Disconnect the hose at the sink end in order to give it a good flush through to get rid of the obstruction. If you are unable to get rid of the obstruction or the pipe is split or worn invest in a brand-new one. If you could get rid of the blockage then put the hose back and start a short program to double check that you have solved the problem.

You may also inspect where the waste hose connects to the waste disposal as well. This is a typical point for blockages to occur so if you happen to take off the pipe give this area a good clean as well.

Examine the drain valve

You may manually inspect the drain valve to make sure it isn’t stopped working. The drain valve will usually be found in the bottom of the machine on the valve bracket. Check your instruction manual if you can’t see it.

Pressing down on the valve or wiggling it a bit should be enough to find out if it’s seized. 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 ring a plumber unless you are undaunted by ordering and swapping out the component on your own.

Examine your pump is not broken

Your dishwasher pump makes use of impellers that may be obstructed by pieces of china or other objects. Check your impellers aren’t broken by removing the cover and ensuring that the impellers can rotate freely.

Listen to your dishwasher while it’s running

If your dishwasher sounds unusual your dishwasher pump or motor could be faulty and need replacing.

Call a plumber
