Hi All,
I have a vaillant TURBOmax Plus boiler which runs the heating and hot
water. Occassionally the boiler doesn't ignite (electronic ignition).
It tends to be oer common if the boile hasn't been used for a while
(i.e. in summer when heating not in use). The auto ignition is
definitely working (I can hear it clicking) but the flame doesn't
light.
Now strangely, the problem seems to have completely dissapeared in the
last 6 months, but prior to that it was getting quite bad, with the
boiler locking itself off for safety reasons. It would rty to light
for about 30 seconds, then lock off.

Does anyone know what can cause this to happen, and if I need to have
the boiler services? Vaillant would offer no advice over the phone
other than to arrange a £90 visit by an engineer...

Thanks,
Matthew

P.S. I ought oto add that the manual doesn't offer a solution to
intermittent lighting.
