New Hot water pump still running constantly after boiler cuts off

[Robert Douglas]

Scottish Power fitted new pump and claim fault in the tank?? Scottish Power engineer claims fault with sensor in tank however the central heating pump switches off when rads at temp. A Bastian pump was fitted in place of the Grunfos one - I've insisted he returns to fit a Grundfos one as I believe pump is faulty and also hums really loudly Google searches suggest it could be a PCB issue - Ideal Boiler in place. Engineer coming back in 3 days- any ideas??

Is this a shower type pump, or heating pump for heating and hot water?
