Vaillant boiler packed up last winter. Traced fault back to some overheated bit of the PCB (see middle of photo). The part I bought here has clearly had the same fault and been repaired, so it was exactly what I needed at a fraction of the cost of a new one. Pleased to report that the boiler seems to be working now that it’s freezing cold. Only worry is that you can’t be sure how long a repaired second hand PCB will last.

following a breakdown of my boiler due to a faulty main board, I fitted this refurbished replacement in about 15 minutes - just pull out all the plugs and wires (having taken a photo first) then fit new board as a reversal of the procedure. on firing up the boiler it threw up fault code f70 - this is nothing to worry about, you simply have to program the new board for what boiler you've put it in, which I did by googling for instructions.
