Spa Error Codes – The Big List

by

spa-and-hot-tub-error-codesThe best thing about digital spas and hot tubs – those with a spa side control panel – is that you are given error codes for most equipment problems. Spa error codes can be somewhat cryptic, but when you have the BIG LIST of CODES, you can immediately define the two or three digit source of trouble.

Problem is, there’s not much consistency among the error codes used by different spa pack manufacturers. Each company uses its own conventions for naming the various system faults.

Hence the need for a BIG LIST of CODES. The alphabetical list of hot tub error codes below covers all major manufacturers of spa controls, including ACC, Balboa, Brett Aqualine, CTI, Dream Maker, EasyPak, Gecko, Hurricane, Jacuzzi, Len Gordon, Maax, Pinnacle, Spa Builders Group, Spa Quip, Sundance and Vita Spas.

Is it an Error Code, or a System Status Code?

Not all spa codes are errors to inform you of trouble. In fact, many codes are used to provide information about system mode, status or equipment operation. Some system status codes are identified as well, with the phrase “system message, not an error.”

So here it is…

The Big List of Spa and Hot Tub Error Codes
