i woke up this morning to my tunze driver alarm beeping, i checked to make sure the pump and impeller were clean and still the impeller won't turn, i put the pump back in the water without the front housing to see if the impeller turns and it does about 1/4" the wrong way, this is causing the impeller stoppers to activate and thereby causing the alarm. what can i do to fix it? it seems that calcium buildup is not the problem, instead it's the impeller attempting to spin the wrong way!!
i bought the unit here on RC and so dont think it still falls under warranty
this is for the tunze 6100
