I have an Ariston class HE 30 boiler the pump has packed up and I have a replacement pump 60000591 the electrical connection to the circuit board is different to the existing, the supplier seems to recall a similar situation happening in the past and put it down to a short run of different pumps being used by Ariston, he got over it by using something from another pump, do you have any idea what this could be? or how we can get over this anomaly??
