Glow insert displaced in metal housing (replace glow
igniter)
 Ionisation electrode defective
- Short circuit monitoring electrode (
observe ignition of the burner in the start phase;
if flame was present: monitoring
circuit is the cause!) Watch out for
short circuit between cable and housing in particular!
- Burner stocking braid has a short circuit to earth to
the ionisation electrode
- Ionisation electrode cable is resting on earth
(in the burner or on motor cover)
 Air in gas pipe
 Gas tap closed
