Aye your right Tony, but as usual I always try to do things on the cheap, the plummer is a friend of a friend and is trying his best, he is not self employed so any purchased parts have to be paid for.
Thanks anyway.

Thanks for that I hoped you would reply as you seem to know exactly what the fault is due to your earlier post. if that pump was not getting a signal to work would it possibly be the pcb,
If the pcb was at fault would the system not even try to fire up, let alone fire up the switch itself off...
Hi, I have exactly the same fault, a local plummer said its the pump on the left, we replaced that but still banging at the downstairs boiler, he now wants to replace the PCB, I am just worried that if I pay to replace that and it still dosnt fix the fault i will be up the creak.
Please advise...
