I've got a 19 year-old Marquis 214 (a small two person 115v tub, aka "Rendezvous") hot tub, and it's not getting hot. Just warm.
It's been working fine for over a month.
I just cleaned the the plumbing with Ahhsome, drained, refilled, and now it won't get up to full temperature.
Maybe running continuously (tub normally takes 18-20 hours to reach max temp because of 115v) finally caused a problem.
Tub is correctly set to 104 degrees, but is stalled out at 89, sometimes 88, sometimes 90, but around there. Digital readout says that, confirmed with in-tub thermometer.
From looking around on some forums with similar problems, sounds like it could be:
Temperature probe
Hi temp cut out switch (heater safety switch)
Temperature sensor
Thermal regulator
I'm not even sure I have all these things or if they're the same thing. Well, I've got a sensor in the tub and a sensor right after the heater (see photo below). I guess my question is: can somebody point me toward how to troubleshoot/diagnose the sensors?
Thanks!
