Therefore, before you call a dishwasher repair service here is a lineup of probable issues you could correct yourself. Some of which aren’t even a fault of the dishwasher itself.
If you’re fortunate the standing water you have discovered may not be an issue at all. Instead, the cycle could have been stopped mid-way.
The cycle may have been stopped mid-way for multiple of reasons. Little fingers pushing controls, mistakenly pressing against the buttons, a power cut or opening the dishwasher mid-program could all interrupt the program and mean your machine doesn’t drain.
If you think this could be the situation, or you feel it might be a good idea to check start the dishwasher again on a short program.
A proportion dishwashers might have a drain program meaning it’s worth consulting your instructions or doing a quick internet search to find out.
If your dishwasher is connected to a garbage disposal check this before you do anything else as a blocked garbage disposal will prevent the machine from emptying. Run the garbage disposal using plenty of water to ensure there are no blockages.
If you do find an issue drain cleaner or a natural alternative could be sought after to unclog the obstruction and so this may fix the issue.
If you sink is draining reluctantly this could signify an issue with the pipes instead of a fault with your machine.
In the case that the kitchen sink is draining inefficiently you may try putting some bicarb and white vinegar down the drain, leaving it for a few minutes, then rinsing it away with boiling water.
A sink plunger might also be utilized to try and remove the obstruction.
This could be enough to allow your appliance to work again so start a short program now. If not you may manually remove the standing water using a bowl as well as a towel and have a look at the next few possible issues.
At this point make sure you unplug the machine to prevent electrocution.
If in the process of one of these investigations you suspect you may have detected and solved the problem there is no need to continue to the next issue. Just start an empty program to make sure your dishwasher is fixed.
Any number of things could block the filters including popcorn, paper from tupperware, plastic film covers and smashed glass. Clear film may also be hard to spot if you don’t look closely.
Remove the filter and give it a good wash before replacing it. Not all filters are obvious and easy to remove so you could need to look at the manual for this.
The next component to check is the waste water hose. Stuck food, a kink in the hose or a crushed hose can all stop your dishwasher from draining.
Contingent upon the position of the waste pipe (usually the ribbed one) you could have the means to view it by removing the base or you might need to pull the dishwasher away from the wall.
Look at the pipe first to see if it has been crushed or kinked. You may manage fix these issues by hand which is likely to solve the issue, but be aware that once this has occurred it is much more inclined to happen again so you might wish to purchase a spare hose.
If you can’t find anything you can disconnect the waste water pipe from the machine and blow through it to discover any blockages. Be sure to line the floor with newspaper or towels before you remove the hose as even if you have emptied the dishwasher there may still be water in the pipe.
If you can’t blow through the waste hose this might be the problem.
Take off the other end of the hose and then give it a thorough flush through to get rid of the obstruction. If you can’t dislodge the obstruction or the waste hose is cracked or worn invest in a new one. If you may remove the blockage then put the hose back and run a quick cycle to make sure you have solved the fault.
You can also check where the waste pipe connects to the waste disposal as well. This is a typical point for a build-up of gunk so if you do remove the waste pipe give this connection a thorough scrub as well.
You could inspect the drain valve by hand to check it hasn’t seized. The drain valve will usually be situated in the bottom of the dishwasher 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 adequate to tell you if it’s stuck. If you can see anything stopping it from moving remove this. If you are unable to, this might be the right time to ring a repair person unless you are undaunted by ordering and swapping out the part yourself.
Your dishwasher pump uses impellers that could get obstructed by pieces of china or other objects. Check your impellers aren’t broken by removing the safety cover and checking that the impellers are free to move.
If the dishwasher doesn’t sound right your pump or motor may be broken and need to be repaired.
If you have been through the above list and the fault remains, or you suspect the pump, pump valve or motor are damaged, it might be the moment you need to get the professionals.
This way though you will at least be able to give them more information and have prevented needing to pay a big call-out charge for a blocked hose.
