My boiler kept cutting out and needed reset button to be used to restart.
Have just had thermostat replaced and problem still occurring.
Any ideas PLEASE! Having great difficulty keeping "GRIZZLY" under control
I had the same problem,there were two dry joints on the PCB, a very good heating technician found the problem, and re-solderd the joints. Took 40 mins charged me £65,and serviced it aswell.

Try not to have thermostat (numbered dial on front) set to high, might help.
