Why Is My Dishwasher Pump Not Stopping? The Shocking Truth Revealed!
What To Know
- The pressure switch monitors the water level in the dishwasher and signals the pump to stop when the water reaches the desired level.
- A leaking drain valve can cause water to seep out of the dishwasher, triggering the pump to run continuously to replenish the lost water.
- A loud noise from the dishwasher pump may indicate a clogged drain hose or drain pump, a faulty pressure switch, or a damaged pressure hose.
A dishwasher is an indispensable appliance in modern kitchens, making dishwashing a breeze. However, when the dishwasher pump refuses to stop running, it can be a frustrating and perplexing problem. Understanding the reasons behind this malfunction is crucial for finding an effective solution. This comprehensive guide will delve into the various causes of a dishwasher pump that won’t stop, empowering you with the knowledge to diagnose and resolve the issue.
Common Causes of a Non-Stopping Dishwasher Pump
1. Faulty Pressure Switch
The pressure switch monitors the water level in the dishwasher and signals the pump to stop when the water reaches the desired level. A faulty pressure switch may fail to detect the correct water level, causing the pump to continue running indefinitely.
2. Clogged Drain Hose or Drain Pump
Clogs in the drain hose or drain pump can prevent water from draining properly. As a result, the dishwasher may continue pumping water in an attempt to clear the obstruction.
3. Leaking Drain Valve
A leaking drain valve can cause water to seep out of the dishwasher, triggering the pump to run continuously to replenish the lost water.
4. Malfunctioning Water Inlet Valve
The water inlet valve controls the flow of water into the dishwasher. If the valve fails, it may allow excess water to enter the dishwasher, causing the pump to run without interruption.
5. Damaged Pressure Hose
The pressure hose connects the pressure switch to the dishwasher tub. If the hose is damaged, it may leak water, causing the pressure switch to malfunction and the pump to continue running.
6. Faulty Electronic Control Board
The electronic control board is the brains of the dishwasher, controlling all its functions. A faulty control board may send incorrect signals to the pump, causing it to run excessively.
7. Overloaded Dishwasher
Overloading the dishwasher can prevent water from circulating properly. This can lead to the dishwasher not being able to drain efficiently, causing the pump to continue running.
Troubleshooting Tips
1. Check for Clogs
Inspect the drain hose, drain pump, and dishwasher filter for any blockages. Remove any debris or food particles that may be obstructing the water flow.
2. Test the Pressure Switch
Disconnect the pressure switch from the dishwasher tub and blow into the hose. If the switch doesn‘t click or make a sound, it may be faulty and need replacement.
3. Inspect the Drain Valve
Check the drain valve for leaks. If water is leaking, replace the valve.
4. Replace the Water Inlet Valve
Turn off the water supply to the dishwasher and disconnect the water inlet valve. Replace the valve with a new one.
5. Repair or Replace the Pressure Hose
If the pressure hose is damaged, repair or replace it as necessary.
6. Reset the Dishwasher
Unplug the dishwasher from the power outlet and wait a few minutes. Plug it back in and see if the pump stops running.
7. Contact a Professional
If you are unable to resolve the issue yourself, contact a qualified appliance repair technician to diagnose and fix the problem.
