I've been having trouble with the topside control on my 2005 Del Sol Hermosa Spa (manufactured by Sundance). So I shut it off for about an hour the other day and when I turned it back on, the following flashed on the topside control display:

5 5 5
8 8 8
0 = 7

It's the last code that's got me confused! I understand what the first two are. Anyone have any ideas what 0 = 7 might be?

Thanks.

Is the spa run well after those codes ? If not, it's probably the circuit board. I hope for you that the spa is still under warranty. A circuit board is about 500$ to 800$.
