I was having trouble with my SWCG. I replaced it and found that it still didn't work but it had a different issue. The issue had to do with the relay in the K1 position on the pcb. I re-soldered the relay and the SWGC is working like a champ. However, when I turned the power on to check the system, the pump wouldn't turn on at high speed. I can select high speed while in service mode but nothing happens. I don't hear a relay or anything. I can select low speed and it everything works.
How do I go about troubleshooting this? Is there an easy way to isolate the problem to the relay? Is it possible the pump is having a problem?
