We have had a Biasi M90 24S for about two years.
Fitted new thermostatic shower approx. 4weeks ago and since then boiler started to lock out (red light on). Never happened before.
But then started to lock out every few hours at a time, worked well with CH but intermittent with DHW (turned DHW on a 50/50 if locks out)
last few days it locked out every hour or so
Today will not ignite whatsoever and when resetting, cannot here the normal clicking when trying to ignite.
Please can anyone offer any advice on likely fault of continuous lock out and now the ignition problem
Many thanks...
