Welcome to TFP.
Your pump drive has a problem.
Drive needing service usually means expensive replacement. How old is your pump?
*17,16, 02, 08, 04, 06, 09, 0A – Internal Errors: These errors can occur based on operating conditions and the UL 60730 required self-diagnostic safety software. If they do not clear after multiple restart attempts, the drive should undergo a hard power cycle. Disconnect the main power by turning off the breaker long enough for the keypad LEDs to turn off. After power is reconnected if one of these errors continues to reappear, the drive may need service.
