Hi all, I noticed last time I used my cooker that the water circulation wasn’t at its usual force. I initially though the circulator part might be dying, but it turns out that the screw holding the impeller blade to the bottom of the drive shaft had come lose, and the impeller was barely turning. There were no errors or beeps to indicate a problem.

So, if you’re the type of user who doesn’t often remove the base or skirt, it might be worth doing so every once in a while to check that everything is still nice and tight. Also good to check for non-existent corrosion ;-).
