Are you finding that your dishwasher will finish a cycle but when it is complete, the bottom of your dishwasher is pooled with water? There a few simple tricks to figuring out why your dishwasher won't drain. If you cannot fix the issue yourself, you will need to call in an appliance repair professional to get the job done right for you.
The following is a few simple simple ways to find the issue with your dishwasher:
1. Check your sink drain:
Is your sink drain clear? There may be food particles and other debris blocking your main drain, causing your dishwasher to not be able to drain properly. If you can run water down your sink drain and not have it pool in the bottom of your sink, this means your main draining pipe is clear and draining properly.
2. Drain pump needs to be replaced:
First you must check that the drain hose, sink drain, and sump are all clear from a blockage to ensure this is not the issue. If all of these are clear and not blocked, it is likely your drain pump that is repeatedly failing and not pumping out all the water in your dishwasher. You can take a look at your drain pump for visible cracks and dents, this can show you if it is your drain pump that is the issue. It may of failed and needs to be replaced, this is not always visible to the naked eye and this is when a professional technician should come in to replace this for you.
3. Drain path must be cleared:
There are multiple different areas in your dishwasher system that could be getting clogged and causing your dishwasher to not be able to be drained. These problem areas are either your sump, pump, sink drain and/or drain hose. All of these parts of your dishwasher can buildup with grim and grease, causing your dishwasher to not be able to drain properly. You must clear the drain path which will allow the water to begin draining freely out of the tub. While doing this, replace any parts that appear to be showing signs of damage.
4. The drain line must be cleared:
This is the part of the dishwasher that moves the water from the dishwasher tub at the end of every cycle into your piping system. This must be cleared of any grease, grim, and food particles or replaced if it is showing signs of damage.
5. Electronic Control Board Needs to be Replaced:
The electronic control board is what controls every aspect of your dishwasher. It controls all the moving parts and guides the dishwasher through all of it's cycles. If your control board is not telling your dishwasher to drain when it is supposed to drain, it needs to be replaced.
6. The Timer Needs to be Replaced:
The dishwasher's timer tells each individual part when it is it's turn to begin doing it's job. If you timer is broken, it will fail to tell your dishwasher to drain when it is the appropriate time. If this is the case, it is best to replace the timer to allow your dishwasher to begin operating optimally again.
7. Check Valve Needs to be Replaced:
A check valve prevents additional water from backing up in the sump after the dishwasher has drained itself. If water is backing up in the sump after the draining process is complete, the check valve may need to be replaced.
8. Check Upper Pump Assembly, it May Need to be Replaced:
Check your upper pump assembly to ensure there is no food particles, grease, or debris causing it to improperly operate or fail which will not allow your dishwasher to drain. If this is not the case, your upper pump may need to be replaced.
This is a short list of reasons your dishwasher may not be draining. It is always best to leave it up to a professional to fix the issue. Call in an experienced technician from Appliance Repair Pros Edmonton to get the job done for you!
