The one on the left, the two speed pump with five wires. Vaillant part number 178983 if it's the one with control knobs. The later version has only buttons and never came with a Wilo.
hiYes, and you have to change the whole pump, not just the head. But it's quite easy really.
SorryYou should not be changing the pump yourself because a DIYer should not be opening the room sealed cover to your boiler.
Nor should the others who have replied to you be encouraging you.
See the forum rules!
Its also obviously a cheap installation!
