This is the first time posting to this forum, but have gotten lots of good info from here. Great site!! Have a problem not quite sure where to start. Have a 98 Blue Ridge Spa that was inherited from family. Hot tub has been up and running and working great! Came home the other night and went to use the tub and nothing was working. GFCI was tripped and would not reset. Used the tub the night before and everything was working great.We have had heat index in the 110's 115's all week. Tried to reset the high limit switch and it will not reset. (acts like it is stuck). Next unplugged everything to try to figure what was tripping the GFCI ( it would not reset either) Figured out the heater was making it trip. Unplugged it and everything works! Try to plug it back in and it trips immediately. Even with tub running without the heater plugged, still cannot get the high limit switch to reset. (Again acts like it is stuck and will not push in).Before investing in the heater, is it possible the high limit switch could be bad and there fore not able to reset the heater? Have not had any problems with heater before. any insight would be great. oh yeah the heater says it is an Aquatemp 5.5 kwh 240v ( hot tub is wired 220) Thanks in advance!!

The high limit will only reset if it's kicked out due to an overheat condition (water at 125 degrees F or higher). The button will pop out when tripped. I'd bet money that your heater element is bad. It is the number 1 most common reason for a spa to start tripping the GFI and in your diagnosis pretty much already points to it.

I'll Second the motion.

Hi Limit switches really kinda suck for user feedback. Even when one is actually tripped out, it only takes a micro-ounce of pressure to reset it, leaving the owner/user to wonder if he actually did anything.



ha... we sell hundreds of spa heater elements every month. I need an emoticon for rotflmao.

(Nothing against you Mr B, but I see it all the time in the field and we hear it daily from online customers - it was working just fine until 'yesterday'...).

Symptoms are classic for a bad heater element. It just happens.

Thanks for the info, won't be able to shut down tub until next week, but the way the heat is around here, it won't matter much until then anyway.
