Updated to add, a new heat pump unit sorted it. Somehow I’d failed to see that the outer vanes ( but still in one piece ie a ring of blades) on the impeller had parted company with the inner part….obvious when the new part arrived. So thanks for the help.

Ah, found the problem, there are spring wires that support the heater element, one had snapped off leaving the other to vibrate against the element eventually breaking through. I’ll replace the element one last time, if it can’t survive without any support ( I’ve removed the remaining wire) then it’ll be a new machine as replacing the wire springs looks impossible…new drum isn’t worth it obvs.

Thanks for your help. I’m away at the moment but decided that I’ll have a look at the main pub, if nothing obvious I’ll replace the pump and the sensor you mentioned…I’ve sort of decided that the satisfaction I’ll gain from it being repaired for £150…outweighs the sadness having to pay out £800 for a new one (it’s integrated) will cause….and I’ll still have a couple of spare pump / heaters I suppose….if they’ll fit..
Thanks again

Thanks for the quick reply. I had megger tested the heater cct, clear @ 500v ( I was an industrial electrician). My problem is not knowing whether the heater cuts in first, before the motor or does the water need to get up to temp before the motor runs or is there another sensor that’s not being satisfied etc, or….however clear the motor readings are, it could still be faulty, impeller spinning on shaft before it gets up to speed for example…I just don’t know if the control panel is asking for the heater / motor, is it worth removing the control panel? Is there a relay in there that may not be closing or are the relays solid state?
Would an experienced repairer just try replacing the heat pump?
