  5. Re‑power the machine and test if the error clears.

Technician Only Test and replace the pressure switch if faulty

  1. Verify power is disconnected and move the machine to a safe workspace.
  2. Access the pressure switch and associated wiring inside the cabinet.
  3. Use a multimeter to test the switch functionality and continuity during simulated water level changes.
  4. Inspect wiring and connectors for damage or corrosion; repair or replace as needed.
  5. Replace the pressure switch assembly if testing confirms failure.
  6. Reassemble and test machine operation for proper cycle progression.

Parts needed: pressure switch, pressure switch hose, wiring/connectors

🛑 When to Call a Pro:
  • If user‑level checks (hose clearance) do not clear the code.
  • If there are signs of internal leaks or water inside the machine base.
  • If pressure switch wiring appears damaged or testing indicates internal sensor failure.
