Peerless Error E20: False Flame Detected
Blocking (auto-reset) error — the control senses a flame when none should be present. Firing is blocked as a safety precaution until the false signal clears. We diagnose and repair it across Greater Vancouver — same-day and after-hours.

Peerless 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 Peerless error E20
- Flame sensor shorted to ground or contaminated
- Lingering flame / glowing debris visible in the observation port
- Moisture or carbon bridging on the flame-sensing electrode
- Damaged flame-sensor wiring
What you can safely check
- Do not attempt to inspect the burner flame yourself
- Have a technician check the flame sensor for shorts and contamination
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.
