My 3.5 year old Jandy ePump has the dreaded "pump offline" error - I'm still not sure what the problem is, however, other threads have suggested the motor driver. I'm guessing a service call to diagnose is going to start at $200+. I have seen the gen 1 epump motors for around $600, but honestly I really just use two speeds - slow for normal filtering and max power for the spa - so is the stealth epump pump housing the same as the regular stealth? Can I just replaced with a two speed motor that will hopefully last more than three years and cost 1/2 as much?
