potterton suprema 40 boiler wont stay on?

Potterton Supremas are renowned for duff soldered joints on their PCB's because they saved manufacturing costs. You can get decent replacements at a respectable price from cetltd.com

most probably it is the pcb that is faulty, ours has went faulty once before and cost £150+ to replace (maint contract in place now). Search web for the same problem as it is common occurance.

Our own potterton suprema 40 has a fault at the moment that the heating works but it is producing no hot water (wheres that number for our maint contract)

Hope you get sorted
