this moring i woke to my tunze 6100.10 not working i removed the single
controller to find only very low flow from pump tried to turn up on the
tucbelle driver but it stoped the pump i tried cleaning the pump but still the
same all this and no alarm

I would start by looking at the stickied thread on driver alarms and making sure everything is clean, in a case like this if it isnt a dragging or broken propeller assembly part, it will be a motor that is dying.
