Printed circuit board failure on first generation Vaillant ecoTEC Plus boilers is extremely common and may present itself in various ways.

Common symptoms of printed circuit board failure on Vaillant ecoTEC boilers include fault codes such as the F27 fault code, F61 fault code, F62 fault code, F64 fault code, the “con” fault or any combination of these fault codes.

When a printed circuit board fails completely the boiler with cease to function, leaving you without heating or hot water.

Unfortunately the printed circuit board on Vaillant ecoTEC boilers are programmable but non serviceable components, which means that nothing can be done to extend the life of a printed circuit board.

What our customers say about us…

I’ve used Richard to service my boiler for several years. He is extremely professional, knowledgeable and thorough. The first time he looked at my boiler he fixed a problem that several other engineers had failed to fix, and even refunded me when a part he had bought turned out not to be needed. Real integrity and a desire to do the best for his customers. I don’t think you’ll find anyone better.
