Many thanks for the previous answer, much appreciated. I've had another look at the machine and noticed that on each of the options / programs the machine , after a few seconds, flashes a red light on RINSE+ and then shows C4 fault code. Would this more likely point towards the pc board? Thanks

the pcb is diagnosing a fault which it believes is coming from a faulty circulation pump.it can't diagnose pcb its self so you have to check external before condemming pcb as they are expensive
