Today, we will be looking at the reasons why many GE dishwasher owners face drainage issues along with ways to resolve them. A faulty dishwasher can make your day tiring and hectic. In this Do-It-Yourself guide, we shall also be looking at ways to avoid these issues in the future. There are numerous reasons why a dishwasher stops draining. They are listed below:
- Clogged filters
- Clogged/faulty drain pipe
- Clogged sump assembly
- Faulty drain pump
- Faulty drain check valve
- Faulty drain solenoid
- Using the wrong type or excess detergent
- Clogged chopper blade area
- Clogged air gap
The reasons mentioned above are responsible for causing a drainage issue in your GE dishwasher. But before moving on to addressing our focus issue, let’s take a look at how a dishwasher works to understand the causes behind its drainage problem in a better way.
GE Dishwasher Working Procedure
In general, a dishwasher is a machine used for washing dishes, so you don’t need to do it manually. It is fed with water and detergent to wash and clean the dishes kept inside it. A control panel is present on the outside, which sets the timer and programs other settings for a wash cycle. On the inside, there are two racks, one at the top and one at the bottom. These keep the dishes in place during a wash cycle. There are two sprayer arms, one located under the bottom rack and the other over the top rack.
The wash cycle starts as soon as it is programmed, and the sprayer arms start spraying water on the dishes. The water gets mixed with the detergent sprayed on the plates by the detergent dispenser. The water washes the dishes and leaves the wash area through the sump inlet and drain hose. The debris gets filtered out through various fine & coarse filters present inside the dishwasher, which you can clean later.
Now that we know how this machine works and the possible reasons behind its drainage issue, let’s address them one by one.
1. Clogged Filters
A filter screen is the first filter that is under the bottom sprayer arm. To access it, you need to remove both the racks, then remove the bottom sprayer. Then you’ll see the filter held by a hub nut. Remove it and check for any signs of debris or food particles. Clean it well under running water if you find any debris.
There is another filter inside the drum, which is known as the coarse screen. The coarse screen is under the filter screen. It is a widescreen used to filter out any big particles. It too can be removed to check for any debris or stuck food particles. If any debris is present, you must clean it thoroughly by washing it under running water.
2. Clogged/Faulty Drainpipe
A drainpipe or a drain hose is the pipe that connects the outlet of the dishwasher to the sink. You should check this pipe for any debris blocking the path of the outlet water. It typically is behind the dishwasher. To access it, you need to remove the dishwasher from the countertop by unscrewing the screws that hold them together.
Once done, you’ll see a pipe coming out and connecting with your sink. That is your outlet pipe. You can check for any blockage by removing it from one end and then looking inside. If everything is clear, it is good to go. Otherwise, you need to clean it.
Sometimes, the pipe could also be broken instead of having a blockage. To check for it, look for any cracks or holes. If you find any, replace it with a new one.
3. Clogged Sump Assembly
After washing the dishes, the residual water runs down through the sump cover, into the sump, and then into the inlet, from where it gets pushed out into the drainpipe. The water can carry some debris or food particles inside the sump, so checking it for any blockage becomes necessary.
Once you remove the sump cover, you can find its filter, which can be removed and checked for debris. Once removed, you will see some standing water inside, which is OK. Check that area for any debris and clean it if you find any.
Then there is the drain check valve present inside. It is a pipe that allows the water to get out but restricts its opposite movement. You should check it for any blockages. Usually, you will feel a rubber flap that restricts the water from coming back inside the dishwasher. But if there is any debris, you’ll feel it and then will require a clean-up.
If the drainage problem persists with your GE dishwasher after this, you should get your drain check valve replaced as you cannot repair this.
4. Faulty Drain Pump
A drain pump drains the water out from the dishwasher into the sink via the drain hose. Sometimes, the drain pump is the reason behind the improper drainage of water. A drain pump uses an impeller to push the water out into the drainpipe. If your GE dishwasher is not draining correctly, it could be the fault of the impeller present inside the drain pump.
To check it, you need to access the backside of your GE dishwasher. Then using a multimeter, you’ll have to check for continuity. If the multimeter beeps, then it is Okay. Otherwise, you’ll need to replace the pump.
5. Faulty Drain Solenoid
The function of a drain solenoid is to control the movement of the drain water from the drain valve. It is the reason why the water drains from the dishwasher. To check if your GE dishwasher’s drain solenoid is working, you need to access its backside.
To check it, unplug the dishwasher from the primary power source and remove the back panel. The drain solenoid is attached to the main pump. It moves when the wash cycle starts and ends. You need to push it downwards to check if it’s moving. If it moves, then it’s okay. Otherwise, it needs replacing.
To reconfirm this, plug in your dishwasher and start a wash cycle on it. If the solenoid moves both at the wash cycle’s start and end, it works perfectly. But if it doesn’t move at all, then you need to replace it.
6. Using The Wrong Type or Too Much Detergent
While using your GE dishwasher, you should not only be careful about your filters but using the right type of detergent or rinse agent in the correct quantity. Sometimes, using too much detergent causes the detergent dispenser to dispense large amounts of liquid inside the wash area. This could cause over-sudsing or suds forming inside the wash area. These big clogs of detergent are easily visible and could cause improper drainage in your GE Dishwasher. We recommend reading the instruction manual to get a good idea to determine how much detergent to use according to the number of dishes and the water quality.
We have already discussed six reasons why your GE dishwasher has a drainage problem and how to resolve them. We should also discuss some other notable reasons that could cause a drainage issue with your machine.

Other Reasons for Drainage Problems with Your Dishwasher
Clogged Chopper Blade Area
A chopper blade assembly is usually not found in a GE dishwasher but is sometimes in other dishwashers. It is a device installed near the drain check valve. Its principal function is to cut the large debris or food particles into smaller pieces so that they could quickly go through the drain check valve into the drainage pipe.
It has a mesh behind the blade that prevents the food particles from getting stuck on the motor. This mesh, slowly with time, gets clogged up with debris, which causes the drainage issue in your dishwasher.
It’s easy to access as it is usually under the bottom sprayer arm assembly. Just clearing that area could make the drainage problem go away. But if the problem still lingers, you need to replace the chopper blade and recheck it.
Clogged Air Gap
An air gap is usually near the drain outlet. It restricts the movement of drain water from coming back inside the dishwasher. However, it too gets clogged due to debris and food pieces. If this is the case, you need to access it by removing the air gap cap and cleaning out the debris. This should solve the drainage problem with your GE dishwasher.
