hhreeka Posted May 12, 2017 Report Share Posted May 12, 2017 Help! We live in the middle of Manhattan, and I've had a hell of a time trying to find a hot tub technician here to service our old school cedar hot tub. We've used it for years, but recently it's been automatically shutting off and finally this winter won't turn on. There are two speeds on pump – high and low. When high speed is engaged, it will heat. But it keeps kicking off and going onto the lower speed (after 10 min). When pump is on low speed, heater says “no flow” and won’t maintain the temperature. We think that the pump on low can’t push water through the system (my husband says maybe due to the original plumbing and the weird curves ?) or maybe we need to buy a stronger pump? We replaced the heater 5 years ago, although my husband did it himself and not sure we got correctly sized pump. We also have never replaced the electronics. Do I have to find a hot tub technician? Can a mechanical engineer or electrician service this? Any ideas of where to troubleshoot? Quote Link to comment Share on other sites More sharing options...
Jersey Hot Tub Repair Posted May 13, 2017 Report Share Posted May 13, 2017 Check your filters. A dirty filter at low speed restricts water flow enough to give a FLO error, where the additional power at high speed enables heating.

hhreeka Posted May 14, 2017 Author Report Share Posted May 14, 2017 Thanks Dave! Unfortunately it does this even with a brand new filter. :-/ Quote Link to comment Share on other sites More sharing options...

When you say it heats at high speed, is the heat LED turning on, or are you just noticing the water in the tub getting warmer? The reason I ask is because the tub will heat up just from the friction of the pump. In NJ at this time of year, I'm seeing about 90-92 as the highest a tub can go from pump friction without the heater working. No heat on low speed and heat on high speed indicates a flow problem, which is why I suggested checking the filter. (I'd also try running without any filter to see if it will heat at low speed.) High speed turning off and coming on at low speed after 10 minutes is not normal. I can see it going into low speed because it's not heated to where it's supposed to be, but the high speed should stay on for 20 minutes before it turns off. So, it sounds like you may have two issues. First, you're not heating and second, your pump shutting off. I don't know anything about gas heaters, so I can't begin to guess what's going on there. High speed shutting off after 10 minutes sounds like an electric problem. Let me ask, did you actually time it, and does it actually quit after exactly 10 minutes? What happend if you press high speed right after that happens? Does it run in high speed for another 10 minutes? Dave Quote Link to comment Share on other sites More sharing options...
