is a pcb replaceable on a bosch dd pwn 15.60 boiler pump

Probably not... speak to these people:

Design sounds a bit naff if its not repairable by getting parts, only by some company. Brian

Plumbers want to change boilers. They don't want to repair PCBs as there's no money in that.

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.

Isn't it rather that plumbers don't have the skills and the test gear to do it?

which is why you have 'heating engineers', who do. But they will only replace PCBs. Not repair them

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.

We had a variation on this at our Village Hall. "No spare parts, but I know a very good company who could fit a new one."
