Biasi Intermittent Lockout / Unstable Operation

Water heater frequently locks out and requires manual reset, with no consistent error code.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose electrical connections, Intermittent sensor failure, PCB dry joints, Fluctuating gas supply

Safety: Isolate power before tightening any internal connections.

Steps:

Record conditions: Note when lockouts occur (e.g., during high demand, windy weather) to help pinpoint the cause.
Inspect connectors: Gently press all plug-in connectors on the PCB and sensors to ensure they are fully seated.
Check gas supply consistency: If other gas appliances also misbehave, contact your gas supplier.

Note: Intermittent faults can be complex; a Biasi-trained technician may need to monitor the heater and test components under load.
