Washer-dryer does not detect water level correctly; may stop with E10 or show erratic fill/drain behavior

Safety first: Unplug the appliance and close the water tap.

Step-by-step checks:

• 1. Inspect pressure hose and chamber:
  • Locate the small hose from the tub to the pressure sensor.
  • Remove the hose and blow through it; if blocked, clean or replace.
  • Check the tub connection (pressure chamber) for soap scum buildup; clean carefully.
• 2. Check the pressure sensor:
  • Ensure the connector is firmly seated and free of corrosion.
  • Measure sensor output if you have the service data; replace if readings are out of range.
• 3. Wiring to control module:
  • Trace the harness from the sensor to the control board.
  • Look for pinched or broken wires; repair as needed.

When to call a technician: If the error persists after hose and sensor replacement, the control module may be faulty and should be checked by a professional.
