Hi,
I have an old Potterton Boiler with a Nest Gen2 that have been working flawlessly for years, however suddenly im faced with the boiler tripping the RCD when its in the igniting phase. 19 out of 20 times it will trip before it ignites, and on the odd occasion it will ignite and heat for a brief period before tripping.
Any idea's on cause and what to check for?
