How to Tell if Ge Dishwasher Control Board is Bad?
When the GE dishwasher isn’t working correctly, you should first check the control board. The control board is the dishwasher’s “brain” that controls other functions and components. A bad control board can cause a wide range of issues with its performance.
But how to tell if ge dishwasher control board is bad?
Let’s examine the signs of a bad control board, its effects, and how to diagnose and fix the problem.
Signs of a Bad GE Dishwasher Control Board
1. Unresponsive Buttons or Touchpad
The first sign of a faulty control board is when the buttons or touchpad on your GE dishwasher become unresponsive. You may find that pressing the buttons doesn’t elicit any response from the appliance, or certain functions may work while others don’t. This inconsistency in button functionality often points to a problem with the control board.
2. Erratic Behavior or Unusual Behavior:
Strange behaviors like the dishwasher running partial cycles, skipping steps, or displaying error codes can all point to a malfunctioning control board. The board is responsible for coordinating all the dishwasher’s functions, which can lead to unpredictable behavior when it fails.
3. Display Issues
Many GE dishwashers have a digital display showing the selected cycle, remaining time, and other information. If you notice the display flickering, showing incorrect information, or not lighting up, it could indicate a problem with the control board.
4. Failure to Start Cycles
When you select a wash cycle and press start, nothing happens; it might be due to a bad control board. The board is responsible for initiating the wash cycle, and if it’s faulty, it may fail to send the necessary signals to start the process.
5. Incomplete Cycles
If your dishwasher starts a cycle but doesn’t complete it or skips certain parts of the cycle (like the rinse or dry phase), this could indicate a control board issue. The board coordinates the timing and sequence of each cycle stage, and a malfunction can disrupt this process.
6. Improper Water Levels
The control board regulates the amount of water used during each cycle. A bad board can cause the dishwasher to use too much or too little water, leading to poor cleaning results.
7. Failure to Drain Properly
The control board also controls the drain pump. If it’s not functioning correctly, the dishwasher may not drain the water fully at the end of the cycle.
8. Inconsistent or Lack of Heat
Proper temperature control is critical for effective dishwashing. A faulty control board can prevent the heating element from reaching the correct temperatures.
9. Unusual Noises
While many dishwasher noises can be attributed to other issues, persistent beeping or clicking sounds that don’t correspond to regular operation might be linked to a failing control board.
10. Completely Dead Dishwasher
In the most severe cases, a bad control board will cause the entire dishwasher to stop working altogether, with no power or response from the controls.
Effects on Dishwasher Performance
A bad control board can have significant effects on your GE dishwasher’s performance:
- Inconsistent cleaning results: Your dishwasher may not correctly execute wash cycles due to a faulty control board, leading to dishes not being thoroughly cleaned.
- Energy inefficiency: If the control board isn’t functioning correctly, it may cause the dishwasher to run longer than necessary or use more water and electricity than required.
- Potential damage to other components: A malfunctioning control board can send incorrect signals to other parts of the dishwasher, potentially damaging pumps, motors, or heating elements.
- Safety concerns: A bad control board could sometimes fail to shut off certain functions, potentially leading to overheating or electrical issues.
- Shortened appliance lifespan: Continuous operation with a faulty control board can stress other components, potentially shortening the overall lifespan of your dishwasher.
How to Fix a Bad GE Dishwasher Control Board
After figuring out that your GE dishwasher control board is bad, here are the steps you can take to fix the issue:
Step 1: Verify the Problem
Before replacing the control board, double-check that it’s truly the source of the problem. Consult your dishwasher’s manual for troubleshooting steps and error code meanings. Sometimes, what appears to be a control board issue could be related to other factors like power supply problems or faulty sensors.
Step 2: Check for Warranty Coverage
Contact GE customer service or an authorized repair center if your GE dishwasher is still under warranty. They may cover the cost of replacement and provide professional installation.
Step 3: Order a Replacement Board
In the case, your warranty has expired, you will need to purchase a new control board. Ensure you get the correct model number for your specific GE dishwasher. You can usually find this information inside the dishwasher door or in the user manual.
Step 4: Disconnect Power
Before attempting any repairs, always disconnect the dishwasher from its power source to avoid the risk of electrical shock.
Step 5: Access the Control Board
The control board is typically located behind the control panel at the top of the dishwasher door. To access it, you may need to remove the inner or outer door panel. Consult your dishwasher’s service manual for specific instructions.
Step 6: Remove the Old Board
Carefully disconnect all wire harnesses connected to the control board. Take a photo or diagram the connections to ensure proper reassembly. Remove any mounting screws and take out the old board.
Step 7: Install the New Board
Place the new control board in the same position as the old one. Secure it with the mounting screws and reconnect all wire harnesses according to your photo or diagram.
Step 8: Reassemble and Test
Replace any panels you removed to access the control board. Reconnect the dishwasher to its power source and run a test cycle to ensure everything works correctly.
Other Considerable Factors
While a bad control board can cause many issues, there are a few other things to consider that might mimic control board problems:
- Ensure your dishwasher is receiving proper voltage. Power fluctuations can sometimes cause symptoms similar to a bad control board.
- Loose or damaged wiring can cause intermittent issues that seem like control board failures.
- If the dishwasher thinks the door is open, it won’t start cycles, which could be mistaken for a control board problem.
- A malfunctioning water inlet valve can prevent the dishwasher from filling correctly, leading to incomplete cycles.
- A blown thermal fuse can prevent the dishwasher from starting, which might be confused with a control board issue.
- Sometimes, what seems like a malfunction could be due to incorrect dishwasher use or misunderstanding of its features.
