My Baxi Solo 50/4 PF fires up ok but a relay in the control box has started clicking away approx every 5 seconds. At the same time the main burner appears to fade and re-ignite instantly (you can hear it re-ignite with a small whoosh). Is this likely to be a duff PCB or would something be causing the relay to switch? Also, the main burner and pilot are on simultaneously - is that normal?
NB. 3 weeks ago an engineer fitted a new gas valve and renewed the silicon pipes on the pressure switch (at an horrendous cost) following the main burner failing to light.
