How to Fix / Troubleshooting
Safety: Disconnect power. Heating circuits carry mains voltage.
- 1. Verify correct pressure switch: Ensure the installed pressure switch matches the model's part number. Incorrect parts can cause E33.
- 2. Inspect wiring: Check the harness between the pressure switch and main control board for loose or damaged wires.
- 3. Test switch contacts: Using a multimeter, test continuity of the pressure switch contacts at different water levels (advanced users only).
Due to the interaction between water level and heater safety, this fault is best handled by a professional technician if basic checks do not resolve it.
