Hi. My friend's BOSCH MaXX washer will not drain. I've discovered that the pump impeller has become detached. Can this impeller be re-attached? And if so, how? Thanks.

Bosch MaXX washer not draining due to detached pump impeller

The problem
A Bosch MaXX washing machine would not drain, and inspection found the drain pump impeller had become detached.
Likely cause
The accepted reply says the impeller is normally a push-fit part and its detachment is a bad sign. It may have been knocked off by a foreign object such as a coin. The impeller itself is not available separately, so the pump assembly is likely faulty.
What fixed it
Recommended action was to replace the drain pump rather than try to re-attach the impeller. The discussion does not confirm whether the pump was replaced or whether the machine was repaired afterwards.
Checks to try
  • Confirmed the machine would not drain
  • Found the pump impeller had become detached
Parts or tools mentioned
  • New pump

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello Richard. If the impeller has come off it's a bad sign. They usually push-fit on. They don't normally come off but if hit by a coin or something it can happen. They can't be bought as a spare part so chances are a new pump is required.
