Standing water in your dishwasher could have multiple of causes some of which are simple to solve. Therefore, in advance of calling a dishwasher repair service here is a list of potential things you could identify yourself. A few of which aren’t even a fault of the dishwasher itself.
It is probable that there is nothing stopping your dishwasher from emptying. Instead, the program may have been cut short.
The cycle might have been cut short for multiple of reasons. Kids pressing controls, accidentally pressing against the controls, a power surge or opening the machine mid-cycle could all stop the cycle from completing and mean your dishwasher doesn’t drain.
If you suspect this could be the situation, or you just want to be sure it’s not the issue run the machine again on a short program.
A number appliances might have a drain cycle meaning it’s worthwhile consulting your manual or checking online to make sure.
If you have a garbage disposal inspect this before you move on as a blocked waste disposal will prevent your machine from draining. Run the disposal using plenty of water to ensure there are no obstructions.
If you do uncover a blockage drain unclogger or a natural alternative can be used to clear the obstruction and so this might rectify the fault.
If you sink is emptying inefficiently this might suggest a plumbing issue instead of a fault with your dishwasher.
If the sink is emptying inefficiently you may try putting a little bicarb and vinegar down the drain, leaving it for a while and then rinsing it through with hot water.
A plunger may also be used to attempt to remove the blockage.
This could be enough to let the dishwasher to drain so run a quick rinse and drain program now. If this hasn’t worked you may manually drain the dishwasher using a jug and also a sponge and troubleshoot a few more areas.
Make sure you disconnect the machine to avoid electrocution.
If in the process of any of these examinations you believe you have detected and fixed the problem there is no need to continue to the next step. Just complete an empty program to make sure the machine is fixed.
Any number of things could block the filters including corn kernels, paper from jars, plastic film lids and broken glass. Clear plastic lids can also be hard to spot if you aren’t looking for it.
Remove the filter then scrub it thoroughly before replacing it. Not all filters are obvious and easy to remove so you could need to consult the manual for this.
The next area to examine is the drain 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 could all stop your dishwasher from draining.
Contingent upon the position of the hose (usually the ribbed one) you may manage look at it simply by lifting away the base alternatively you might need to move the dishwasher out from under the counter.
Visually examine the pipe first to see if there are any kinks or it’s been squashed. You might be able to fix these issues by hand which should deal with the issue, however, it’s worth noting that once this has occurred the probability of it happening again is massively increased so you may wish to order a spare hose.
If you are unable to find anything you could take off the drain hose from the dishwasher and blow through it to figure out if there are any blockages. Be sure to line the floor with newspaper or towels first as even if you have emptied the dishwasher there might still be waste water in the hose.
If you are unable to blow air through the waste pipe this might be the problem.
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 pipe is cracked or worn acquire a brand-new one. If you may remove the blockage then put the hose back and start a short cycle to find out if you have solved the error.
You can also inspect the point where the waste pipe connects under your sink. This is a typical point for debris to build up so if you do take off the waste hose give this point a good scrub as well.
You can examine the drain valve by hand to make sure it isn’t got stuck. The drain valve will usually be situated in the bottom of the dishwasher on the valve bracket. Consult your manual if you’re not sure.
Depressing the valve or giving it a jiggle will likely be sufficient to find out if it’s stuck. If you are able to see something blocking it remove this. If you can’t, this might be a good time to get in touch with a plumber unless you are confident in purchasing and replacing the part on your own.
Your appliance pump makes use of impellers that can become obstructed by pieces of glass or other debris. Check your pump isn’t obstructed by removing the cover and making sure the impellers can rotate freely.
If it sounds unusual your pump or motor might be broken and need to be repaired.
If none of the above investigations has solved the problem, or you think the pump, pump valve or motor are damaged, it may be time to call in the professionals.
At least having tried to fix the problem yourself you have avoided having to pay a big repair fee for a blocked drain.
