No-one is happy to open their dishwasher and discover it hasn’t emptied properly but, try not to overreact just yet. You might manage rectify the fault by yourself, without having to call a repair person or invest in a new machine.
Your machine refusing to drain may have multiple of causes a few of which can be simple to fix. So, before you call a dishwasher repair service here is a lineup of probable components you can identify by yourself. A number of which are not even a fault of the machine itself.
It is possible that there is nothing stopping your dishwasher from emptying. Alternatively, the cycle may have been cut short.
The cycle could have been stopped mid-way for multiple of reasons. Children pressing controls, accidentally pushing against the buttons, a power cut or opening the dishwasher mid-program might all stop the cycle from completing and mean your machine doesn’t empty.
If you think this could be the circumstance, or you feel it might be worthwhile checking run your dishwasher again on a quick cycle.
Some machines could have a drain program so it’s worth consulting your owners manual or consulting google to find out.
If your dishwasher is attached to your disposal check this first as an obstructed disposal will block the dishwasher from draining. Turn on the garbage disposal using lots of water to ensure there are no blockages.
If you do find a blockage drain un-blocker or a plunger may be used to remove the blockage and so this could deal with the fault.
If you kitchen sink is draining slowly this may indicate an issue with the drains as opposed to a problem with your dishwasher.
If the kitchen sink is emptying inefficiently you may try putting some bicarbonate of soda and vinegar down the drain, letting it sit for a while, then rinsing it away with boiling water.
A plunger might also be employed to attempt to remove the blockage.
This may be enough to allow the dishwasher to work again so start a quick cycle at this point. If not you may manually drain the dishwasher using a cup and a sponge and check a few more possible issues.
At this point make certain to turn off the dishwasher to avoid electrocution.
If during any one of these checks you believe you have detected and repaired the issue you don’t have to go through the remaining steps. Just start an empty program to make sure the dishwasher is repaired.
Popcorn, labels from food jars, plastic covers and broken glass, plus food debris, may all block the dishwasher filter. Clear plastic lids can also be difficult to spot if you aren’t looking for it.
Remove the filter and clean it thoroughly before replacing it. Not all machines have their filter in the same location so you might need to refer to the owners manual for this.
The next area to inspect is the waste hose. Stuck food, a kink in the hose or a crushed hose may all prevent your machine from emptying.
Contingent upon the position of the hose (normally the ribbed one) you might be able to look at it simply by lifting away the base or you might be required to pull the machine out from the wall.
Visually examine the pipe first to see if it has been squashed or kinked. You may manage manually fix any kinks which should solve the issue, but be aware that when this has happened it is much more inclined to happen again so you may need to order a replacement hose.
If you can’t see an issue you could remove the waste hose from the pump and blow into it to discover any blockages. Be sure to put down newspaper or towels first as even if you have emptied the dishwasher there might still be water in the hose.
If you are unable to blow air through the waste pipe this might be the reason your machine isn’t draining.
Disconnect the other end of the hose in order to give it a good clean to clear the obstruction. If you are unable to remove the obstruction or the hose is cracked or worn invest in a new one. If you could clear the obstruction then replace the hose and run a short cycle to make sure you have solved the issue.
You can also examine the point where the waste hose attaches to the sink as well. This is a common place for debris to build up so if you happen to take off the waste hose give this point a thorough clean as well.
You can inspect the drain valve by hand to ensure it isn’t seized. The drain valve will generally be situated in the bottom of the machine on the valve bracket. Check your instructions if you’re not sure.
Depressing the valve or wiggling it a bit will likely be adequate to find out if it’s stuck. If you can see any debris stopping it from moving get rid of this. If you can’t, this might be a good time to ring a repair person unless you are undaunted by ordering and swapping out the component yourself.
Your appliance pump makes use of impellers that could become obstructed by broken glass or other debris. Check your impellers aren’t blocked by removing the safety cover and ensuring that the impellers can rotate freely.
If the dishwasher sounds unusual your dishwasher pump or motor might be broken and need to be repaired.
If you have been through the above list and the error remains, or you think the pump, pump valve or motor are damaged, it may be the right time to get the professionals.
At least having tried to fix the problem yourself you have prevented having to pay a big call-out charge for a blocked drain.
