Hot Tub Problems
I have a 7-yr old LA Spas Model - Islander 2900. Suddenly yesterday the tub
is not heating, and the second set of Jets (panel says "Jet B") are not pushing out water. A few weeks ago I did the periodic draining and refilling of water, and replaced the filters and two jets that had their top nozzles broken off. Yesterday, the temperature dropped from 95F to 65F. I live in Maryland, and the current outdoor temp is 46F, and the tub is still reading 65F. My guess is that the heater is not heating the water up to 65F, but that it is retaining this heat. When I press "Jet B", I hear a motor noise, but no water movement. I'll probably need to call a repair company, but any insight is appreciated. |

They will be close to the pumps in the lines that go in and out of the pumps. It sounds like you have gotten air in there, and it can't burp it out. It sounds this way to me because you get the noise but not the flow. It will be a small knob device. Be careful not to tighten them down too tight. They have an O ring, and snug is good enough. Hope this is your problem. Steve |

Hope this is your problem. Steve Thanks but is this related to the no-heat problem? You say right at the start of your post that two jets are not pushing out water. If they aren't pushing out heated water, how can they heat the spa? Spa diagnosis is a series of elimination. You need to first find out why those two jets aren't flowing. One of the most common things is to get air into the lines when draining. Sometimes the air will burp out, and all will be fine. If it doesn't, it won't pump HEATED water. Start there. If this is the problem, you just saved yourself a $100 service call. If not, at least you know where the bleeders are so that next time, you can do it properly. When you drain and refill, if the area around the heating element fills with air, the element comes on, and will overheat until the limiting device kicks it off. Not a good thing to do, as this element is designed to operate with water around it. If it is getting thin, this is the perfect scenario for it to burn through completely, giving you a major repair job/bill. As I said, find the bleeders and bleed them. Open them up until you can see bubbles or water coming out. Kick the pumps on and off and see if it can catch prime. If and when it does, let it run and see if it will pump hot water. You may have already blown the element by running it with no water in the heating chamber. Once you get all the jets flowing, then go on to see if the heater is working. You're getting the cart before the horses here. If the jets are working, but the heater is not heating, check reset buttons, and check fuses. Kill all power to the unit, pull the control panel cover, and look for fuses, and check them with a continuity tester. Mine are available really cheap at Home Depot. HTH, and good luck. Steve |

When I press "Jet B", I hear a motor noise, but no water movement. I'll probably need to call a repair company, but any insight is appreciated. The "no water" indication may be disabling the heat. They will not heat if they think they don't have water flowing. Try the bleeding Steve mentioned but you might have a bad imperller in the pump. First of all, when the set temperature is higher than the current temperature, only the A jets come on to bring warm water in to raise the temperature. It was the B jets that wouldn't flow when the B jet turnon button was pressed. The A-jets were fine. B-jets come on only when you get in and want flow out of B-jets. I contacted the seller of the hot tub, and they advised there is a B-jet diverter valve on top of the tub (you can close the valve to prevent B-jets from coming on), to remove it to let the air out and this should get the B-jets going again. They called this condition an air lock and said it occurred when I drained and refilled the tub, and that it could potentially result in compromised heating. I did this and B-jets work again. However, the water still is not heating up. What's strange is I drained and refilled the water several weeks ago, and the temperature heated right up and was fine until this week. Now that B-jet flow is fine, I don't know why the water won't heat up. Steve B implied that the heater element may have overheated and is broken, but the heat was fine for a couple weeks after I drained and refilled the tub, and B-jet flow has nothing to do with heating the tub. Again, when the temperature is below the set point only the A-jets are designed to turn on. Unfortunately now I've got the service call in and am waiting until later this week to get whatever the problem is fixed. |
