I have a Tunze 6100 that is one of the older models with the 7240.26 driver. It was working fine and then once I put it on the multi-controller, the alarm started going off and it quit working. The impeller still spins and it pushes a little water but not much. I took the impeller out and I don't see anything wrong with it and it dosen't appear to need cleaning. How do I find out about having it fixed and the cost of repairs?
Thanks
