I have a 2001 Caldera spa, the pumps are currently both not working... They weren't making tons of noising or causing any issues and all of the sudden just stopped working...
The panel has power and when I click the jets button I hear a relay clicking in the panel. I removed the panel and checked and I believe the pumps have power running to them, but neither is turning on. I can see a light in the ozonator box coming on, so I know power is flowing out of the control box.
