Welcome to Just Answer, My name is XXXXX XXXXX X'XX do my best to help with your issue.Since you've already tried a new capacitor the next step would be to replace the motor but it would probably be easier to just replace the whole pump. The work involved with replacing the motor probably isn't worth the effort compared to what you would save over the cost of a new pump
I understand that, however, it has been discontinued by Kohler and they directed me to Gross Automation and they will repair the motor for a flat fee of $500.00.
Can you think of any way of bypassing the control board to power the motor directly? I was unable to find a wiring diagram, and made an assumption that the Black and White wires going from the control board to the motor were the motor wires. There are others (Striped and Orange etc.) but they may be for the integrated heater. I just wan to be sure it is the pump before I kick out a minimum of $500,00
That was my guess, but trying to identify the motor feed is the issue. What is you opinion on a aftermarket replacement vrs. a repair fo the exsisting pump. Aftermarket $199.00 repair $500.00. The only change is I have to replace the acuation switch.
