2000 Cal Spa (No Heat)

[ggbelsky]

I was recently given a 2000 Cal Spa Jacuzzi (not sure of a specific model)by a friend (it worked fine last time he turned it off). It has a panel on top that says GE electric, and the board says Balboa Instruments 2100 wiring system. There was a rat that got under it and chewed two or three of the small wires, which I have fixed. I filled the tub, the jets work, the blower works (on the option button), and the lights work fine. There is a little green light on the panel for suction safety mode which light up. But when I hit heat it starts at 100 and goes up to 104, blinks several times then goes back to 62 and blinks EC. Anyone have any idea what this could be? (The heat light indicator on the top panel is not lighting up either). Any help would be appreciated.

Does the heat light ever come on? If not, then your problem is going to be on your control side. Either thermostat, pressure switch, temp sensor, etc. From your description it sounds like you might have a high limit issue. If the spa is heating from 100 to 104 and then cutting off sometime after that, you might have a bad high limit sensor. In case you didn't know, the high limit is a safety switch designed to kill power to the heater when it gets too hot. Usually around 110 degrees.

Another possibility is the blinking EC. Newer spas have what's called "economy mode". This means that the tub will only heat during a preprogrammed filtering cycle. If this is the case, just put the tub in "standard" mode and you should be fine.

Did you find any further information out on this unit? My mother has a Jacuzzi and is experiencing this same issue. Is it possible it is a voltage problem?

EC is economy mode as stated above. You can turn it on or off on the panel by pressing a specific sequence. If you need to know how I can see on mine but can't remember off hand. And the Temp display shows current water temp until a temp + or - is pressed then it shows the thermostat temp for a few seconds and goes back. So it sounds like the panel is working correct. You just have a heater issue. Could be as simple as a fuse or relay. Just thought I would give some input since I have a 2000 Calspa also.
