My Goldline/Aqua Rite gave out a few years ago. The unite has had problems since I've had it first year they gave me another cell second year they replaced the circuit board no charge to me. The short time it worked correctly it was convenient. So now I'm thinking of replacing it or fixing it. So looking on line I see some people will fix the cir cute board for a flat rate, one guy on ebay it would cost about $60 with shipping, not a bad price. Still your dealing wit ebay. So has anyone ever had one repaired ? I did replace the varisistor that did nothing. So then on Amazon they have the circuit board, Display PCB and T cell-15 for around $700. but not sure if it would fit my box. Also See some other brands available any good ones?
