Dishwasher is Not Draining: Here are the 9 Reasons Why

Outline:

Summary:  it’s frustrating to wake up one day only to find out your dishwasher is malfunctioning. Seeing a pond of standing water rather than sparkling clean dishes can be a nightmare and must be dealt with as soon as possible. If not, it can lead to bacteria build-up and a disgusting mess.

In this blog post, we will reveal to you some of the most common reasons behind this.

Dirty Filter

If your dishwasher is not draining, the first thing you must examine is the filter. This is an integral component of a dishwasher and has to be maintained regularly to keep your appliance running efficiently. The filter traps mushy and moist food particles. Not to mention, it prevents excess food and grease from accumulating in the dishwasher.

On the other hand, filters can be blocked easily if they aren’t cleaned regularly. It is highly recommended to clean your dishwasher filter once a fortnight to keep away from dirty plates and make your appliance last longer.

Clogs or Kinks in the Drain Hose

Greases, oils, and fats can cause the water in your dishwasher to drain slowly. But they are not just related to garbage disposal. You have to change the connecting hose, which runs from the appliance to the disposal. This can become clogged or kinked; thus, impeding or slowing the water’s passageway.

However, the issue could also lie in the kitchen sink. A clogged sink drain can be fixed easily if you have a drain snake or a plunger. If you don’t have tools or know nothing about a handyman’s job, then calling the experts is a must. 

Damaged or Broken Down Drain Pump

Like a dishwasher filter, a drain pump is also prone to blockage by surplus food particles, built-up oils, and grease. This will stop the water from being drained after a series of washing cycles. Any particles that might have found their way to the drain pump can typically be found next to the impeller, a rotor that increases fluid flow and pressure.

Foreign objects like broken glass can also slip easily into the drain dump and stop the pump from functioning. You‘ll hear the drain pump struggling if there is an issue. Checking the pump requires access to the base of the appliance. This means you must detach the inlet hose and eliminate the base plate. You will also need to take a resistance reading with the help of a multimeter to make sure the drain pump is working correctly. If you feel uncomfortable doing any of these tasks or don’t want to risk voiding your dishwasher warranty, contact a trustworthy dishwasher repair company in Waco, TX to fix your appliance.

Trap and Dirty Filter

Make sure your dishwasher has a filter. Try to find the model name of your appliance. Usually, it can be found inside. Google what you see and find the owner’s manual to know the particular location. Better yet, browse YouTube to watch tutorials.

Usually, it is under the revolving piece below the lower tray. Once you have found the filter, lift it out of its holding spot and check the sump below for other food particles. The last step is to clean the filter thoroughly and replace it. Do another run and see if there are developments.

Liquid Detergent

If your dishwasher is not draining, that has something to do with the detergent you are using. Most dishwashers are suitable for powder detergent. You may have used liquid in a pinch, as it does a fantastic job cleaning the dishes. However, it can make a lot of suds that water can have a difficult time draining after the cycle. You can fix this by putting in the correct type of detergent. If you keep the liquid route, you will want to lessen the amount you are using, given that this is the problem.

Garbage Disposal Blockage

Another thing to test out if you find out that your dishwasher needs to be draining water is the garbage disposal. There is a hose that connects the dishwasher to the garbage disposal. This hose allows the runoff somewhere to go.

If the garbage disposal is clogged with grease or food, water flow or movement out of the appliance can be held up. This leads to the water standing effect. You will want to test out the garbage disposal thoroughly for food particles. Sometimes, allowing it to run for 10 to 15 seconds addresses the issue. If it doesn’t, call a professional appliance repair company near you.

Blocked Air Gap

If your dishwasher is not draining properly, that can induce a lot of stress on you. That is especially true if you haven’t had it long enough to be experiencing the slow drain problem. However, fret not. You don’t need to call the appliance store to argue with the warranty. Instead, consider cleaning the air gap.

This component is indicated on the sink by a tiny cylindrical covering that unfastens and houses the air gap. Get a small brush and tweezers to eliminate grime and obstructions. Then, run the appliance to a cycle and see if there is an improvement.  

Frozen Valve

You might also be experiencing a defective water inlet valve. This component is located in the wiring at the rear of the control panel, and the bottom panels can give out or freeze up. When it does, it will have an issue shutting off the water flow into the dishwasher, or it will not give access. The latter can explain why you are experiencing pooling or standing water. 

Power Source Failure

Have you examined the breakers or outlets? Are they functioning properly? If all else does not succeed, this may be what keeps the dishwasher from draining properly.
