Hello all, I'm new to Pool Spa Forum and also for the hot tub/spa subject. Please forgive me for my lack of knowledge. I tried every search engine to find this in-ground spa brand but did not have much success. Does anybody recognize this hot tub brand in the picture? How old (roughly) is this unit? ______ Here is the full story behind this, and I have a few more questions if you have time to read. The house I purchased a few months ago came with this in-ground hot tub, and it was listed as a non-functioning item. After all the hours/yard cleaning and renovations, I finally got free time to look at the hot tub. It was covered with a heavy wooden panel, and it seems the hot tub was not used for years (tenant confirmed they did not use it for six years at least.) The acrylic/fiberglass tub had few inches of old dirty water left with some residue. I cleaned up everything and washed the tub. I filled the water and turned the two pump switches (picture 6), everything seems to be working fine. Jets working, Water circulation pump is working, heater turned on and seemed working fine too. These are the equipment this system has, Jandy LXi gas heater (runs on natural gas) Jandy Pro Series CS200 filter Two separate pumps (for water circulation and jets) Air pump (very loud) Of course, the first round of water was full of dirt/dark-colored. I removed the water and cleaned the filters (Jandy CS200, canisters 1 and 2.) Filled up again with water, added liquid chlorine (Home Depot brand and added a little over half a gallon), let it run for few hours. Removed water again and cleaned the tub shell, filters. Filled up with water for the 3rd time, added liquid chlorine, circulated for few hours every day for a week (now water is clear), pumped the water out again. Now the tub is empty, as you see in the pictures. I ordered a new filter for the Jandy CS200 to replace the old filter. I will fill water again, run one more time for a week, and remove the water for the 4th time before using it. I know this is an old hot tub, but I would like to use it until the heater/motors fail (if possible) and maybe replace this with an above-ground new hot tub. I appreciate it if can help me to identify/replace few things, and some advice, What else should I do before I use it (I will do the water PH, alkaline, chlorine balance)? Hot tub jets are old and brittle (Picture 3, 4 & 5.) I need to replace them (if possible) and want to know how to remove them. I was managed to pull two fish eye parts out (picture 5) but not the whole unit that I need to replace. Two small holes in each side of the jet cover (picture 4) are just plastic hole. Not screws or anything in it. How can I remove yellow stains on the tub shell? (stains from old water and organic materials left for years). I tried bleach, white vinegar, alcohol but had no luck of removing them. Do I need to run both pumps all the time when I use the hot tub? Can someone please explain to me the pump/filtration process in picture 6? I appreciate if you have time to help me with this project.

The blower on my heater runs continuously even when the heater is off. I have to cut the power at the breaker box to stop it. When I attempt to start the heater the ignition control box's red light flashes once indicating an air flow fault. Since the blower is running I can't imagine the fault is a lack of air. Do I need to replace something? Air pressure switch?

So my Jandy Heater has the Shorted H20 Sensor fault - does this mean the pressure switch has gone bad? Is this easy to replace? Jandy LRZ 400ep Thanks!

Hi, I'm trying to start up my 7 year old Jandy Lite2 for the first time this spring. I'm not sure what the model number is, but its the one without the fancy display and with the pilot generator. I've cleaned almost all the wire connectors by removing them and scrubbing the contact points with steel wool and scraping them with an exacto knife. I can get the pilot light to start and stay on but the main burners won't fire up. I don't have a lot of experience with these things, but from what I gather, the pilot heats a generator which then powers the gas valve. There's a black box looking thing below the control panel where several wires feed into and there's a little red LED light - last year I remember seeing that thing flash every few seconds, but this year I don't see that - then again its pretty bright out today so maybe I'm missing it. But does a flash of this light indicate that the pilot generator is working ok? I've also read in some places that a multimeter can be used to check the pilot generator .. How would I do that? Would I put a black probe on one of the contact points coming from the pilot generator and a red probe on the other? Thanks! Dan
