View current alarms, get more info, and access alarm history.
Provides guidance for specific alarms and troubleshooting steps.
Unit locks out after 27 failed ignition cycles; troubleshooting steps provided.
Flame rectification signal lost three times in one heating cycle; check gas pressure, vents, rod.
Intake pressure switch opens due to blockage in intake venting; check wiring and tubing.
Proof of Fan switch is open during heating; check wiring, tubing, and air intake.
Proof of Fan switch is open during pre-purge; check wiring, tubing, and blower operation.
Proof of Fan switch is open during post-purge; check wiring, tubing, and air intake.
Exhaust pressure switch opens due to excess pressure in exhaust venting.
Proof of Fan switch is closed when blower is off; check blower operation and switch continuity.
Tank temperature exceeded allowable temp; check probe, wiring, and ECO switch.
Combustion gases are too hot at exhaust tee; check wires, elbow, Molex, and sensor readings.
Control senses flue temperature sensor is open or disconnected. Refer to A017.
Control senses a short in the flue temperature sensor or wiring harness. Refer to A017.
Water temperature probe not connected or thermistor damaged; check Molex, wiring, and resistance.
Upper tank temperature exceeded 205°F; check probe, wiring, or ignition board.
Short detected in ECO/temperature probe or wiring. Refer to A022.
Control does not detect blower RPM; check blower voltage, wiring, or blower itself.

Water leak detected by control; check for leaks, sensor, or resolve leak.
No water detected; ensure tank is full, check for anode alerts, and follow diagnostic steps.
Gas pressure switch is open; check wiring, inlet gas pressure, or replace switch.
Lower tank temperature sensor is open; check harness, resistance, or replace sensor/board.
Short detected in lower temperature probe wiring; check probe, wiring, or board.
Unit fails ignition 9 times, gives A029. Refer to A001 for troubleshooting.
