I can't recall if this boiler has an overheat thermostat which requires
manually resetting. If it has find it and test it for being open circuit.
The basic unit does not come with a overheat thermostat. Potterton sell an
add on overheat thermostat kit for sealed systems.

BTW my Potterton Neataheat 16/22 packed up on Boxing day, similar symptoms
except that the fan started then nothing.
Removed control PCB and found a couple of blown tracks. Soldered wire
links across break, no probs since.

Must be a special 'break around Christmas time' setting they all have.

My fan isn't turning however, which indicates to me that the PCB is the 2nd
in line, fan being 1st in line. I.e. if the fan doesn't turn, then the PCB
can't be the fault?
