How to Fix / Troubleshooting

Safety: Unplug the appliance and turn off water.

  • Check pressure hose:
    • Locate the small hose from the tub air trap to the pressure switch.
    • Ensure it is firmly attached at both ends and not split or cracked.
    • Replace if hardened or damaged.
  • Inspect pressure switch:
    • Verify the electrical connector is fully seated.
    • Check for signs of burning or corrosion.
  • Test continuity (for skilled users):
    • With the machine empty, test the switch contacts with a multimeter while gently blowing into the pressure port.
    • Contacts should change state as pressure increases.
  • Check wiring harness: Trace wires from the pressure switch to the control board and repair any breaks.
  • If all components test OK: Replace the main control board.
