if you have had the updated pcb board fitted was the yellow jumper removed
you get a number of led flashes then a 1sec pause which then repeats to give
an indication to what is causing the lockout
also in my experience that boiler need to run with the temp knob setting no
more then 1/3 on

Took a look at the card ( ans 2 spares) jumpers 1, 3 & 4 are fitted

Not sure why you would want to lower temp ?......... I have an
underfloor heating system, the manufacturers advice was to run boiler at
maximum temp.
So when store call for heat - boiler will work at maximum efficiency ...
they advise running at lower temp will reduce efficiency.
