What To Know
- The impeller is the rotating blade inside the pump that creates the pressure to push water.
- If it experiences a malfunction, it can send incorrect commands to the pump or other components, resulting in the pump not pushing water.
- By following the troubleshooting steps outlined in this blog post, you can identify the root cause and take the necessary actions to restore your dishwasher to proper working order.
Introduction:
The dishwasher, a modern marvel that effortlessly cleans our dishes, can occasionally malfunction, leaving us with a sink full of dirty dishes and a nagging question: “Why is my dishwasher pump not pushing water?” This blog post delves into the depths of this common dishwasher issue, providing a comprehensive guide to troubleshooting and resolving the problem.
Potential Causes of a Dishwasher Pump Not Pushing Water
There are several reasons why your dishwasher pump may not be pushing water. Identifying the root cause is crucial for effective troubleshooting.
- Clogged Inlet Valve: This valve controls the water flow into the dishwasher. If it becomes clogged with debris or sediment, it can restrict water flow to the pump.
- Faulty Pump Motor: The pump motor is the heart of the dishwasher’s water circulation system. If it fails or becomes damaged, it will not be able to pump water.
- Blocked Impeller: The impeller is the rotating blade inside the pump that creates the pressure to push water. If it becomes clogged with food particles or other debris, it can prevent water from flowing.
- Damaged Water Solenoid: This solenoid controls the opening and closing of the water inlet valve. If it fails, it can prevent water from entering the dishwasher.
- Faulty Pressure Switch: The pressure switch monitors the water pressure in the dishwasher. If it malfunctions, it can send incorrect signals to the pump, causing it to stop working.
- Electrical Issues: Electrical problems, such as loose connections or a faulty wiring harness, can disrupt power to the pump, preventing it from operating.
- Control Board Malfunction: The control board is the brain of the dishwasher. If it experiences a malfunction, it can send incorrect commands to the pump or other components, resulting in the pump not pushing water.
Troubleshooting Steps
To troubleshoot the issue effectively, follow these steps:
1. Check the Inlet Valve: Inspect the inlet valve for any visible blockages or debris. If necessary, clean it by removing the screen and flushing out any sediment.
2. Test the Pump Motor: Disconnect the dishwasher from the power supply and remove the pump motor. Connect it directly to a power source and listen for the motor running. If it does not run, replace the motor.
3. Inspect the Impeller: Remove the impeller from the pump and check for any clogs or obstructions. Clean the impeller thoroughly and remove any debris.
4. Check the Water Solenoid: Disconnect the water solenoid from the power supply and use a multimeter to test for continuity. If there is no continuity, replace the solenoid.
5. Test the Pressure Switch: Disconnect the pressure switch from the power supply and use a multimeter to test for continuity. If there is no continuity, replace the pressure switch.
6. Inspect for Electrical Issues: Check all electrical connections, including the wiring harness and power cord. Ensure that all connections are secure and free of damage.
7. Reset the Control Board: If other troubleshooting steps do not resolve the issue, try resetting the control board. Disconnect the dishwasher from the power supply for several minutes and then reconnect it.
