I turned off my pump the other day to clean my filters, and when trying to turn it back on, it would not react to most buttons I pushed giving me a KEY ERROR, key not in use. Sometimes it would prompt for the password but when hitting the Enter middle key I would again get the key error. Pentair tried to help me troubleshooting to no avail and because of the age of the pump (only 5 yrs!!) they said it was recommended I get a new one because the problem seemed to be the DRIVER (which I believe is the computer part of the pump). The driver is not sold by Pentair anymore and online I can find it for $500-$650 range. The good news is that for now it runs on the schedule. Has anybody have seen that issue and able to resolve it?? in the worst of the cases, can the pump be run manually?? Thanks in advance
