2001 PDC Spa with PROPAK SSPA-A-P121-P211 controller board troubleshooting.
Story: Came home to find my GFIC breaker “kicked”. Hmm…didn’t see anything wrong so, I unplugged the motor (this is a 2001 & it only has one motor for the entire system). Reset the breaker (220V setup). Topside (TSC-18) looked normal with the pressure alarm (3 decimals). So, turned it off, plugged the motor back in, flipped the breaker and Voila! Everything worked for about 5 seconds and POP!!!
Looking the provided pictures you will see that the Line#1 on the back of the circuit board popped (circled in Yellow). Also, there appears to be an circuit break within the (red circle) area.
This is a PROPAK SSPA-A-P121-P211-O1-LS-H4.0-AMP-PPD controller.
