Quick answer
Turn off the washer at the circuit breaker to stop it immediately. Check for a clogged drain pump, faulty water level sensor, or control board issues. Reset the machine after clearing any blockages.
Confirm the symptom
- Washer continues to fill or spin without stopping
- Control panel shows no error but machine won't stop
- Drain pump is running but water isn't draining
- Washer restarts cycles after pausing
Tools and prep
- Screwdrivers (flathead and Phillips)
- Flashlight
- Plumber's putty or tape
- Bucket for water collection
- Multimeter (optional for testing sensors)
- Turn off power at the circuit breaker
- Shut off water supply valves
Step-by-step troubleshooting
- Check Drain PumpDo: Locate the drain pump (usually at the front or bottom of the washer) and inspect for clogs.Observe: Debris or lint blocking the pump impeller.Means: Clogged drain pump prevents water from draining, causing the machine to think it's still filling.Next: Clean the pump and restart the washer.
- Inspect Water Level SensorDo: Check the water level sensor and its hose for cracks or leaks.Observe: Water pooling around the sensor or a disconnected hose.Means: A faulty sensor can send incorrect signals to the control board.Next: Replace the sensor if damaged.
- Reset the WasherDo: Unplug the washer or turn off power at the circuit breaker for 1 minute.Observe: Machine powers off completely.Means: A reset can clear temporary glitches in the control system.Next: Plug in and restart the washer to see if it completes the cycle.
- Test Control BoardDo: Look for visible damage on the control board (burn marks, swollen capacitors).Observe: Signs of electrical damage or error codes on the display.Means: A malfunctioning control board may fail to send stop signals.Next: Replace the control board if damaged.
- Check Door Latch SwitchDo: Ensure the door is fully closed and the latch switch is engaged.Observe: Door light not illuminating or the washer not starting.Means: A faulty door switch can prevent the washer from recognizing the door is closed.Next: Replace the door latch assembly if necessary.
- Verify Water Inlet ValveDo: Inspect the water inlet valve for mineral buildup or blockages.Observe: Reduced water flow or inconsistent filling.Means: A clogged inlet valve can cause the washer to overfill or run continuously.Next: Clean or replace the inlet valve.
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Clogged Drain Pump Blocked pump prevents water from draining, causing the washer to think it's still filling. | Common | Easy | Drain Pump Filter or Pump Assembly |
| Faulty Water Level Sensor A damaged sensor sends incorrect water level readings to the control board. | Common | Easy–Medium | Water Level Sensor |
| Control Board Malfunction Electrical issues on the board prevent proper cycle control. | Sometimes | Hard | Control Board |
| Door Latch Switch Failure The switch fails to signal the door is closed, causing the washer to pause or restart. | Sometimes | Medium | Door Latch Assembly |
| Clogged Water Inlet Valve Mineral deposits or debris restrict water flow, leading to overfilling. | Sometimes | Easy–Medium | Water Inlet Valve |
| Faulty Timer or Motor Control Older models may have a timer or motor control that fails to advance the cycle. | Rare | Hard | Timer or Motor Control Module |
Parts matching
If you need replacement parts, match your washer's make and model to the correct components:
- Drain Pump Filter – Often clogged with lint or debris
- Water Level Sensor – May need replacement if cracked or leaking
- Control Board – Required if there are visible burn marks or error codes
- Door Latch Assembly – Needed if the door doesn't close properly
- Water Inlet Valve – Replace if water flow is inconsistent
- Pump Motor – May be required if the drain pump is damaged
Keep your washer's model number handy to ensure accurate part compatibility.
When to call a professional
- The washer still won't stop after cleaning the drain pump and resetting it
- You notice a burning smell or sparks from the control board
- You're uncomfortable working with electrical components
- Error codes persist after replacing suspected parts
- Water is leaking from the machine despite checking connections
FAQ
Can a clogged drain pump cause the washer to run continuously?
Yes, a clogged drain pump prevents water from draining, making the washer think it's still filling, which can cause it to run nonstop.
How do I reset my washing machine?
Unplug the washer for 1 minute or turn off the power at the circuit breaker, then plug it back in and restart the cycle.
Why is my washer not recognizing the door is closed?
A faulty door latch switch may not signal the control board that the door is closed, causing the washer to pause or restart.
What should I do if the control board is damaged?
If the control board has visible damage like burn marks, it should be replaced by a qualified technician.
Can a faulty water inlet valve cause the washer to overfill?
Yes, a clogged or faulty inlet valve can lead to overfilling, causing the washer to run continuously.
