My DIG-220 is about 10 years old and has operated without issue except for cell replacement over all those years. It has just started tripping its dedicated circuit breaker after about 5 minutes of operation. It displays no errors and appears to be generating chlorine during the time it is operating. After closing the breaker the unit will not immediately power up. When it does power up it will again operate for about 5 minutes before the breaker again trips. All fuses check ok using a multimeter. I’m stumped.
