How to Fix / Troubleshooting

Safety first: Turn off power and allow the appliance to cool before inspection.

  • Check water level and filters: Ensure the machine is filling correctly and that filters are clean to prevent pump cavitation.
  • Inspect sump for debris: Remove filters and look for objects that could block the pump inlet. Remove any visible obstructions.
  • Reset: After clearing debris, leave the appliance off for 15–20 minutes to allow any thermal protection to reset, then run a short program.
  • Persistent E20 or grinding noise: The circulation pump motor is likely failing and should be replaced by a technician.
