What is the number of red led lockout flashes you are getting
is the gas valve modulating correctly when it is working


Most of time - it does not lock out, just explosive ignition .........
when the lock out issue was happening (2 months ago)
It was safety lock out ... Red LED flashing aprox once per second.

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
