No-one wishes to open their dishwasher and discover standing water but, try not to lose it just yet. You could have the means to figure out the issue by yourself, without having to call a repair person or purchase a brand-new dishwasher.
Standing water in your machine could have multiple of causes a number of which are simple to rectify. Therefore, before you call a dishwasher repair service try this lineup of potential things you may identify yourself. A few of which are not even caused by the machine itself.
It is possible that there is nothing stopping your machine from draining. Rather, the cycle may have been stopped mid-way.
The cycle could have been cut short for a number of of reasons. Kids pushing controls, mistakenly leaning against the buttons, a power surge or opening the dishwasher mid-cycle may all prevent the cycle from completing and mean your machine doesn’t drain.
If you think this may be the circumstance, or you think it may be worthwhile checking start your machine again on a quick cycle.
Some machines could have a drain program meaning it’s worth having a look at your owners manual or doing a quick internet search to check.
If you have a disposal inspect this first as a blocked disposal will block the machine from draining. Run the garbage disposal using fast running water to ensure there are no blockages.
If you do uncover a blockage drain cleaner or a plunger could be employed to unclog the blockage and this may fix the error.
If you sink is emptying reluctantly this could suggest an issue with the drains as opposed to a fault with your dishwasher.
If the sink is draining slowly you can attempt putting some bicarbonate of soda and vinegar down the plughole, leaving it for a few minutes, then rinsing it away with boiling water.
A sink plunger may also be employed to try and shift the blockage.
This could be sufficient to let the appliance to drain so start a short cycle to check. If not you may manually get rid of the dirty water using a bowl and also a sponge and troubleshoot a few more areas.
Make certain to turn off the dishwasher to avoid electrocution.
If during any of these investigations you think you may have found and solved the error there is no need to continue to the next step. Just run an empty cycle to ensure the machine is now emptying as it used to.
Any number of things could block the filters including corn kernels, paper from containers, film covers and broken glass. Clear glass could also be hard to spot if you don’t look closely.
Take out the filter and clean it thoroughly before replacing it. Not all machines have their filter in the same location so you may need to consult the owners manual for this.
The next area to examine is the waste water hose. Stuck food, a kink in the hose or a crushed hose may all impede your machine from draining.
Contingent upon the location of the waste hose (usually the ribbed one) you may be able to look at it by means of taking off the base alternatively you might be required to move the machine away from the wall.
Have a look at the hose first to see if there are any kinks or it’s been squashed. You might manage manually remove any kinks which will most likely solve the issue, however, be aware that when this has happened the chance of it happening again is significantly increased so you may wish to buy a spare hose.
If you are unable to see an issue you could disconnect the waste hose from the dishwasher and blow into it to check for any blockages. Be sure to line the floor with newspaper or towels first as there could still be dirty water in the hose.
If you can’t blow through the pipe this may be the reason your dishwasher isn’t draining.
Take off the other end of the hose in order to give it a thorough clean to get rid of the obstruction. If you can’t shift the obstruction or the hose is cracked or worn buy a brand-new one. If you can remove the blockage then put the hose back and start a short cycle to make sure you have fixed the issue.
You can also check the point where the pipe attaches to the sink as well. This is a typical point for blockages to occur so if you happen to remove the pipe give this connection a thorough clean as well.
You may inspect the drain valve by hand to make sure it isn’t stopped working. The drain valve will generally be found at the base of the dishwasher on the valve bracket. Check your manual if you’re unsure.
Depressing the valve or wiggling it a bit should be sufficient to find out if it’s seized. If you can see any debris blocking it carefully extract this. If you can’t, this may be the right time to get in touch with a repair person unless you are happy in procuring and repairing the part yourself.
Your dishwasher pump uses impellers that could become blocked by pieces of china or other objects. Check your impellers aren’t obstructed by taking off the cover and checking that the impellers can be easily rotated.
If it doesn’t sound normal your pump or motor may be faulty and need replacing.
If none of the above checks has solved the fault, or you suspect the pump, pump valve or motor are damaged, it could be the right time to call a plumber.
At least having tried to troubleshoot you have prevented having to pay a big call-out charge for a blocked hose.
