No one wants to open their machine only to find out that it hasn’t drained properly, but don’t lose it just yet. You can fix this kind of problem by yourself without having to call a technician or look for a new dishwasher at the mart.
Machines refusing to empty could have a number of different concerns, some of which are quite easy to resolve even all on your own. So, before calling a dishwasher repair service, try out this list of thinkable problems you can fix yourself. Some of these aren’t the fault of the machine itself to begin with.
Ensure the Dishwasher wasn’t Halted Mid-Program
Probably, nothing prevents the machine from draining. Instead, the program could have been interrupted.
The program may have stopped in the middle for a couple of reasons, such as children pressing the controls, accidentally resting their palm on the buttons, intermittent power failure or opening the dishwasher in the middle of the cycle, All of which can prevent the program from completing the process and often result in your dishwasher not draining.
If you think this might be the case, or think it may be worth the effort, run your dishwasher again on a short cycle.
Some appliances may have drain capacity, so it’s worth checking your instruction manual or Google regarding your dishwasher’s brand and model just to be certain.
Check the Garbage Disposal
If you have a garbage disposal, check it before doing anything else as a clogged garbage disposal will prevent your machine from draining successfully. Run the garbage disposal under running water to ensure there are no obstructions.
If you find a clogged drain cleaner or a plunger could be sought after to clear the clog and this could fix the problem.
Check the plumbing for Problems
If your sink is draining inefficiently, it could indicate a problem with the plumbing rather than a problem with your dishwasher.
In case your kitchen sink is draining slowly, you can try putting some baking soda and white vinegar in it, leave it for a few minutes and then rinse it off with boiling water.
A sink plunger can also be used to try to unclog the obstructions.
This might be enough to allow the machine to drain, so run a quick rinse and empty cycle
at this point. If that didn’t fix the problem, you can manually empty the dishwasher with a bowl and towel and check for the following possible issues.
Be sure to disconnect the machine from the power supply for safety purposes.
If any of these checks indicate that you have discovered and resolved the problem, you do not need to proceed to the next problem. Just start an empty cycle to check if the dishwasher is finally fixed.
Check and Clean Filters
Popcorn, container paper, plastic lids and broken glass, and food debris can clog the machine’s filter. The transparent film can also be difficult to see unless you look closely.
Take out the filter and clean it inside out before inserting it back. Not all filters are recognizable and easy to uninstall, so you may need to consult the instruction manual.
Is the Waste Pipe Obstructed?
The subsequent area to look at is the waste water hose. Many things could cause a blockage together with a buildup of food remains, a twist in the hose, or a damaged hose. All of that can all obstruct your dishwasher from draining.
Depending on the placement of the waste hose (usually the corrugated one) you can have the means to view it simply by taking off the base or you could move the machine far from the wall.
Look at the pipe first thing to learn if it’s been damaged or twisted. You may also have the means to repair those troubles by hand which have to resolve the problem. However, it’s really worth mentioning that after this has happened, the possibility of it happening once again is more likely, so that you may want to desire to acquire a hose replacement.
If you’re not able to discover any visible twists or obstructions, you may dispose of the waste water pipe from the machine and blow into it to figure out if there are any blockages. Be certain to line the ground with newspaper or towels first as there may nevertheless be water within the pipe.
If you can’t blow through the waste hose, this is probably the purpose your machine isn’t draining.
Disconnect the hose at the sink end and then give it a thorough cleaning to put off the blockage. If you’re not able to dislodge the obstruction or the waste pipe is cracked or worn, acquire a brand new one. If you’re successful at eliminating the obstruction, place the hose back and start a brief program to find out whether you have repaired the problem or not.
You can also look at where the waste pipe connects to the sink. This is the usual area for a buildup of gunk, so in case you do dispose of the hose, you should provide this connection a drastic cleaning as well.
Inspect the Drain Valve
You might also need to take a look at the drain valve with your hands to ensure it hasn’t seized. The drain valve will usually be positioned at the bottom of the machine at the valve bracket. Check your instruction manual if you’re having a difficult time in locating it.
Pushing down the valve or giving it a wiggle ought to be sufficient to allow you to realize if it’s seized. If you see or feel something preventing it from shifting, remove it. If you’re not able to, this is probably the best time to get in touch with a plumber, unless you’re satisfied in shopping and replacing the valve on your own.
Check if your Pump is not Obstructed
Your dishwasher’s pump uses impellers that can become clogged with broken glass or other debris. Check if your impellers are not clogged by removing the cover and making sure the impellers can be spun easily.
Listen to your Running Dishwasher Carefully.
If it sounds unusual, the pump or motor may be defective and need to be repaired or replaced.
Call a Professional
If you’ve gone through the list above and the problem still persists, or you suspect a faulty pump, pump valve, or motor, it may be the best time to call for a reliable appliance repair company.
Even so, you should be proud of yourself for the efforts you exerted to resolve the problem on your own; you’ve at least managed to avoid a high start-up fee for a mere clogged filter.
