Yes it is a vokera compact either a 24 or 28 I think
a 28 cuts out before igniting on water and c/heating
but sometimes ignites I thought it might be the igniter
electrode may need cleaning or the gap to the burner
adjusting.

sounds like you have a vokera option or compact
am i right?
most likely to be ignition control board if cutting out intermittantly
you need to try & give as much information as possible
to help with an accurate diagnosis
otherwise i have to rely on my crystal ball
make
model
if problem affects DHW or CH or BOTH
