Details: 2001 Cal Spa Genesis 110v
Last week I installed a new 1.5 hp hydromaster motor/pump with new unions, new flow switch, new Clear Blue Ionizer and a new filter
When I first turned it on, it heated to 104. The next day I went out and it was 100 and the heater light wasn't on but the water was circulating as if it were heating. I got in and ran the pump on hi and adjusted the temp. When I turned the jets off the heater turned on, but the next morning it was off again. I unplugged it and it didn't heat when restarted. Pump is running, as it would when it is heating.
I cleaned the filter, ran it without the filter, cleaned the in tub strainers, checked for air lock, adjusted the switch, disconnected the switch and still, it won't heat. I also ran a jumper wire between the flow switch connections and got the FL code. Reconnected the switch and no code. The cover is keeping the heat in really well, so I don't think it's losing heat and can't keep up.
Any ideas on next steps are greatly appreciated!
