I will check out the screens today. I am pretty sure the pump is operating correctly. As soon as the safety switch on the door is engaged and the thermostat calls for heat, the pump kicks on and I get a consistent flow. Thanks for your help Keith

I am trying to figure out why the high limit keeps tripping on a pre 1989 Hot Springs Spa Indoor Outdoor model. Heres what is happening: The spa would heat up to temperature and then a few days later the high limit would trip. I checked the circulating pump and all the water lines to the heater and return. There were no kinks in the lines and the pump works fine. I then replaced the high limit switch. The spa heated up and seemed to keep temperature for about a week. Then the high limit switch (I think it was that switch) tripped again. There was a lot of water inside the equipment area. I cleared it out and found a very slight leak at one of the hoses to the heater. The heater has a solid dense insulation around it that was completely soaked. The insulation is now falling apart and needs to be replaced. I am going to replace the insulation to the heater but before I order the part I was wondering if the problem with the high limit switch tripping is being caused by a faulty thermostat. Is it possible that the new high limit switch tripped because the heater insulation was water logged? Ive been scratching my head a lot on this and appreciate any help you can offer!
