Symptoms
- Cycle runs far longer than the selected program
- Machine keeps humming or running water indefinitely
- Buttons don't respond to cancel or stop presses
- Lights or display frozen on one step
Likely causes
- CommonSensor stuck detecting incomplete fill or drainIf the machine doesn't sense a step finished, it can loop trying to complete it.
- PossibleStuck cancel/drain button or unresponsive control panelA stuck physical button or unresponsive touch panel can prevent stopping the cycle normally.
- PossibleControl board malfunctionAn electronic fault can cause the board to ignore the programmed cycle length.
- Less commonWater inlet valve stuck openIf the valve fails open, the machine may keep filling and running in a loop.
What to do
- Try pressing cancel or drain and hold it for a few seconds to force the cycle to stop.
- If buttons don't respond, turn off the dishwasher at the circuit breaker immediately rather than letting it keep running.
- Wait a minute, then restore power and see if it resets to an off or ready state.
- Check whether water is still actively filling; if so, and it doesn't stop, shut off the water supply valve under the sink as well.
- If it happens repeatedly, avoid running it unattended and have a technician inspect the control board and water inlet valve.
- Note when in the cycle it typically gets stuck, since that detail helps a technician diagnose faster.
Tools and parts
- None
When to call a pro
If turning off the breaker is the only way to stop it, or it happens more than once, have an appliance technician inspect the control board and inlet valve.
Safety
Use caution
If the unit won't respond to any button and keeps running, shut off both its breaker and water supply, and avoid leaving it unattended until it's fixed.
