I am the second owner of a California Cooperage 105. According to the previous owner it worked just fine.

When filled up and turned on, it heats to the set temperature and the heat turns off as it should. The problem seems to be that the low jets/pump must be on for everything to work. If I manually turn off the jets it locks down and displays FL.

I can reset it by pulling the breaker (240v). I located the pressure switch and turned it a little and a lot. This would either turn the jets off, resulting in the FL reading or do nothing.

Is this a pressure switch problem? How do I replace it?

Thanks so much!
