HTP fault codes can vary by model and series. Use this as a guide — the same code can have more than one cause. Our Technical Safety BC–licensed technicians read the code, confirm it against your unit's manual, and diagnose the true cause before any repair.
Likely causes of HTP error F00
- Failed tank temperature sensor
- Stuck or failed mixing valve sending hot water improperly
- Control or aquastat fault
- Insufficient circulation/flow
- Scaling or fouling affecting temperature control
What you can safely check
- Use only the manual mixing/tempering valve at the fixtures with caution and avoid hot water until serviced
- Note the F00 code and call a qualified technician; do not attempt internal repair
Beyond these checks, do not open the unit or touch gas/electrical parts — BC law requires a licensed gas fitter. Call us for a proper diagnosis.
Error F00 usually leaves you without heat or hot water and can indicate a safety-related fault. Don't keep resetting it — call for priority after-hours HTP repair.
