Arrived at location on 2/3/22 - Unit showing H20 open error in steam and combi mode. Checked water lever electrode and not open to ground when generator full. Checked wiring harness to board and have continuity to board. Fill solenoid voltage 230v when filling. Manually drained generator and refilled while checking probes t ground and good continuity when water reaching probes. Will order new electrode, harness, and fill valve. If issue persists has to be board. Returned to location on 2/10/22 - Replaced water level electrode, cane and fill solenoid. Tested operation and now steaming. Not throwing error. Ok at this time.
