What does fault code 5 02 mean on Chaffoteaux?

Flame detected with gas valve closed The gas valve remains partially open or closes slowly/is permeating when the control orders closure; check for absence of voltage in coils and perform a tightness/manometer test on the ramp: if there is gas flow without power, the valve is faulty.

What does fault code 5 01 mean on Chaffoteaux?

Absence of flame (ionization not detected after ignition) The gas valve does not open or modulate correctly; check that it receives voltage during the ignition attempt and measure burner pressure. If there is command/voltage and no gas or pressure is out of specification, the valve block is defective or miscalibrated.

What does fault code E 20 mean on Chaffoteaux?

Flame detection with gas valve closed Lockout due to flame detection with the EVG closed: the gas valve is stuck/permeates. Check that there is no voltage in coils during the fault and perform a leak test/flame observation; if there is gas without control, replace the valve.

Code	What does it mean?	Cause and diagnosis (this part)
5 02	Flame detected with gas valve closed	The gas valve remains partially open or closes slowly/is leaking when the control commands closure; check for absence of voltage in coils and perform a tightness/manometer test on the ramp: if there is gas flow without power, the valve is faulty.
5 01	Flame absence (ionization not detected after ignition)	The gas valve does not open or modulate correctly; check that it receives voltage during the ignition attempt and measure burner pressure. If there is a command/voltage and no gas or pressure is out of specification, the valve block is defective or miscalibrated.
E 20	Flame detection with gas valve closed	Lockout due to flame detection with the EVG closed: the gas valve is stuck/permeates. Check that there is no voltage in the coils during the fault and perform a tightness test/flame observation; if there is gas without control, replace the valve.
