I have replaced my boiler pump twice in 6 weeks the engineer says that the PCB is burned out replaced the 13 amp fuse with 3 amp I am now left with a 6 week old pump and was told the pcb is not repairable is this correct
Have you tried Bosch direct I find they are the the best company for getting spares especially for their white goods. Their website has exploded diagrams of their products and any part can be bought without any restriction. It might be different for their Worcester Bosch division but it is worth a try.
Repair men are unlikely to be electronic engineers. The standard repair for boilers, TVs, white goods etc. is to replace a PCB. If the boards are recycled they would be returned to a specialised centre.
It also depends on the state of the board or failure - the OP suggests burnt out but that may just the repair man's definition rather than say a carbonised track on the board. If it was a DIY by a competent person a damaged track could be repaired but someone paid to repair a boiler would be unlikely to go down this route and just replace the whole sub assembly.
And then there is the old BG trick. Spare parts (boards) are no longer available and we can offer a discount on a new boiler. What they really mean is that they no longer want to service the boiler and don't carry the spare parts on their list or stores. A friend of mine used to make a reasonable living fixing boilers etc. with genuine spares sourced from the manufacturer long after BG and other service organisations claimed spares were no longer available.
