Quick summary
Look at the display when it stops: the code is the best clue. PF means a power interruption, LE a motor problem or overload, UE imbalance. Stopping with no code may be a normal soak/balance phase—or a fault needing diagnosis.
Not every pause is a fault; some programs include soaking or load redistribution. Repeated stops with codes or unfinished cycles need methodical tracing.
Unplug the appliance, close the water tap if there's a leak, and never open covers that need tools or expose wiring or circuits.
Possible causes
Power cut or fluctuation
Many models show PF after an interruption.
Motor overload
A very heavy load or large wet items can trigger LE.
Repeated imbalance
The washer keeps rebalancing, extending or stopping the cycle.
Excess suds
The washer detects foam and pauses or adds rinses.
Fill or drain problems
IE or OE halts the program at the affected stage.
Safe checks you can do
- Note the code on the display before unplugging.
- Check the supply is stable and the washer is on a direct wall socket.
- Reduce the load to suit the program capacity.
- Use the right dose of HE detergent.
- Unplug for a minute and restart the program.
When to stop checking immediately
- If LE repeats even with a small load.
- If stopping comes with a burning smell or a tripped breaker.

When do you need a technician?
Based on the code and the stage where it stops, the technician tests the motor and wiring, board, sensors and water path, then runs a full cycle to confirm the fix.
