Rheem Error F006: Flame detected when burner is off
The control still sees a flame (or flame signal) after the burner should be off. This points to a gas valve that is not fully closing, and the unit locks out for safety. We diagnose and repair it across Greater Vancouver — same-day and after-hours.

Rheem 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 Rheem error F006
- Gas valve not closing fully at end of demand
- Flame sensor / electrode reading a false signal
- Moisture or contamination on the igniter/sensor
- Loose ignition-module connections
What you can safely check
- If you smell gas, shut the boiler's gas valve and ventilate, then call your gas utility / a technician
- Do not keep resetting a flame-related lockout
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 F006 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 Rheem repair.
