The new dipenser has the rinse aid connector on the left side of the unit and not the bottom as is the case with the old one.
Not that the position matters, it`s just the plug doesn`t fit.
Another thing I should have mentioned is that my plug only has 2 wires and yet the new PCB has 3 connector points on the rinse aid PCB.
I have just watched a couple of youtube videos on fitting this part and both had three wires to that plug.
