  1. Hi, our spa (about 10 year old) with a Spa Builders S class board isn't really heating. We're getting the 3 flashing dots so I thought I had to replace the pressure switch. The catch though is that when it first powers on, it's fine, it's only after it completes a heat cycle that I get the 3 flashing dots (i.e. disconnect spa when the water isn't that hot (i.e. below 100), reconnect spa and the heater works fine but as soon as it hits 100 and it stops heating, then you get the 3 flashing dots. Even once the water temp drops below where it should start heating again, it doesn't. (you als
  2. Hello all! I didn't get any responses on my last post so am trying again as I have now troubleshooted a bit further. I have a mid-2000s model Hot Springs Vanguard. Everything is working except I cannot get the heat to rise above 98 degrees, even when set to 104. Here is what has been tried thus far: New circulation pump New GFCI 20 amp breaker installed New heater - Note: I had to jump the pressure switch on the board because the new heater does not have the external cord that runs to the circ board Disconnected Ozonator from Circ board (Line was cut p
  3. I have a 2007 Hot Spring Prodigy with temp error lights flashing. I replaced the high limit and thermistor, but no help. I jumped the built in pressure switch and everything works fine. Since the replacement heater does not have a pressure switch, is it ok to run the spa with the switch jumped? Bill
  4. I inherited a 1997 Beachcomber Model 550 that is not heating but I wish it did. Here' what I know: -the motor is running normally and the pump is working fine, both are brand new -there are no error codes on the topside controller but the red heating status light does not come on -when powered up the actual temperature reading is 54F now. Was 56F yesterday which I'm assuming means the water temperature sensor is working -the temperature setting on the controller is set at 100F. I am able to raise and lower this setting but nothing changes in terms of operation -heater element r
  5. I have an older Sundance spa that came with my vacation home. When visiting this weekend, I found an "FL O" error on the tub and it would not heat. (All other functions, blowers, lights etc work). I took out the circulation pump, it appeared to be stuck and then it freed up. I refitted it but it still did not run. I also tested the pressure sensor and tripped it into closing which started the heat but still no water flow (Stopped that after 5 seconds to avoid any burn-out/over heating etc). I'm pretty certain the circulation pump needs replacing, but I want to check it first but am not sure if
  6. I have ordered a Tecmark 3209 for my 1999 Master Spa LS650 and wanted to know if I need to change the setting on the pressure switch or should it be good to go out of the box? My spa has a 24-hour circulation pump if that makes a difference. Thanks! Jeff
  7. Hello. I think my pressure switch is bad and am going to replace it. On my hot tub the pressure switch is pointed toward the back of the tub and looks inaccessible without being able to remove the heater tube. The tube and control panel are all contained in a plastic liner which makes access difficult. Can anybody offer any suggestions? THanks. Jeff
  8. Hydro Spa Endurance - Water change a few weeks ago and have issues ever since. drained and refilled tub. Started it back up and got FLO message. Removed filter and tried to restart to no avail. After researching, thought is may be an air lock. Have cracked all fitting around heater but still have FLO message on startup. If I turn jets on as soon as I power the spa back up, it will run and heat up to the desired temp. and kick off as normal but when temp. drops a few degrees and spa tries to fire heater again, FLO message will appear and will not heat and jets will not come on even if I h
  9. Hi! Im new to this forum, I just acquired a older model Jacuzzi hot tub. The model is 8780000 ( Caressa). Got a pretty good deal on it since it doesnt leak, and all the side wood is in great condition. Its wired for 115vac 20 amp. I ran a dedicated line (gfci of course) and bonded the tub to code. However when we plugged it in the first time we realized it wasnt heating after 24 hours it didnt warm up not even a degree. After looking up some information I realized it could be the heating element. Below is what I did to replace it Unplugged the tub drained the tub to below jet level loosene
  10. 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!
  11. We have a Laars LT 400 pool heater with a flashing pressure switch. The heater does not fire up. It seems we may need to replace the pressure switch? Where is it located in the heater? The diagram is confusing to say the least.
  12. Ok a little back story. Heated the spa about 2 weeks ago. Everything worked fine and the spa heated nicely. Then last weekend put the filter pump on and the pool heater and left to do some things. When i got back home the pool wasnt warm. Go to the heater and the service AGS light is on. Turn it off to try again. Runs about 3 times and then service AGS light comes on again. I can smell gas when it comes on and starts blowing air through the vent so i know its getting gas. So i switch to spa and see if that will heat. But instead of service AGS light coming on, I'm getting the pressure swit
