I’ve had a couple of duff Bosch pumps lately where the Hanning rotor doesn’t have a direct coupling with its impellor and jams up 😕 Brand new pumps straight out of the box, I wasn’t too pleased…. 👿
A case for buying gen pumps really. Never used any bosch or Aeg pattern pumps since an aeg item melted once and burnt out the timer board and door interlock. The later Hanning items certainly dont look a patch on the original Hanning with fan type.
