Mine gave me the 91 code first. Than after following instructions on cleaning (which it didnt even need it, was sqeaky clean) it after just 1 week of use. It started giving me the "service" light, and was not working at all. No chlorine bubbles were being generated. Intex said they can send me another one for free. In the meanwhile, I decided to check online for solutions. Some people spoke of rewiring/bypassing wires in the generator, so I opened mine up and tried it. I AM NOT AN ELECTRICIAN!! But I do know to unhook from the wall first. So the cord needs to first be pulled from the wall. What I did was unscrew the red and black wires from their "terminals" (I think thats what its called) coming from that "little black battery" to the "screw" (on the left side, where there are two black wires and one red and one white wire screwed). Dont unscrew anything from the "battery". Then I hooked the red wire together with the white wire (using same screw already with white wire), then I did the same thing with the black wire coming from the "battery" area and hooked it where the other black wired is. They look like this originally from top to bottom (red/from wall to battery) (black/from cell wire)(white/from cell wire)(black/from wall to battery). U also need to rewire the little red/black wire that is attached to the black fan. It needs to be unhooked where the red/black wire has a white squarelike tip (P1). than rehook it to the other square little "outletlike" thing closest to the fan (P6), left of the three blue squares. DO NOT BOTHER TURNING ON THE HOURS FOR THE TIMER, IF IT KEEPS SHUTTING DOWN THEN IT DOESNT WORK ANYWAY. You will need to time it on a manual alarm for the required time for chlorination (SEE: your manual for your pool size chlorination time). If you turn on the timer, then it goes into "service" light mode, than the fan will also shut down, that can cause things to heat up. But if you just let the "88" stay on the machine will stay on along with the fan. Because remember it is now directly hooked to the main wire leading to the GFCI. I will TRY TO POST video on youtube.
TITLE(cut and pase onto youtubes search bar):>>[Intex Saltwater (chlorine) Generator Bypass wires (Fix) for 8110 GENERATORvideo1]AND for the FAN >>[Intex Saltwater (chlorine) Generator Bypass wires (Fix) for FANvideo1]. i just did this today, so who knows it may heat up and blow up tomorrow. So if you like wait for me to post a positive OR negative remark by next week about the results, maybe sooner. Please note I am NOT responsible for YOUR results, if you attempt to do this, use discression and CAUTION. This post doesnt allow for pics, either that or I didnt figure out how to do it.
