Possible Causes

Defective pressure switch, Loose connector at control board, Faulty main control board input circuit, Damaged wiring harness

Safety: Unplug the unit before accessing electronics.

1. Reseat connectors: Disconnect and reconnect the pressure switch plug and the corresponding connector on the main control board.
2. Inspect harness: Look for pinched or broken wires along the harness path.
3. Replace pressure switch: If wiring is intact, replacing the pressure switch is the next logical step.

If E34 persists after replacing the switch, the main control board is likely defective and should be replaced by a technician.
