Tbstanford Posted December 10, 2017 Report Share Posted December 10, 2017 So I'm new to this hot tub thing. I just got a new filter, but the hot tub keeps flashing "----" on the read out screen. It's an older model, so I need some help please. It an 8 person tub, that about all I know. If I turn of the breaker, and then turn it back on, it resets sometimes. When I get it to reset, it may run for a day, or just 3 mins. Signed. HELP! Quote Link to comment Share on other sites More sharing options...
castletonia Posted December 10, 2017 Report Share Posted December 10, 2017 Pretty sure that is a high limit error. If so, I believe that means either a bad thermistor, heater, or main control board. Quote Link to comment Share on other sites More sharing options...

Jersey Hot Tub Repair Posted December 13, 2017 Report Share Posted December 13, 2017 A hi limit in a Calspa is often caused by a dirty filter. Did you take the shrink wrap off your new filter? Did you drain and refill the tub prior to the problem? It would be quite a coincidence to get a hi limit failure right after changing a filter.

Tbstanford Posted December 13, 2017 Author Report Share Posted December 13, 2017 Yes I took off the shrink wrap. Yes we did recently drain scrub n refill. D/t calcium in the tub. Hard water issues from our well. Quote Link to comment Share on other sites More sharing options...
Tbstanford Posted December 13, 2017 Author Report Share Posted December 13, 2017 Please keep the feedback coming. I appreciate it. Thanks to all that are offering ideas. Fingers crossed. It's been on for 3 days now with no issues. I've been raising the temp little by little. No error codes. As of this am it was up to 92 degrees. Ran it last night 3 times for about 30 mins each time. Tonight might be a true test. It's getting down to the single digits. I plan on putting in chemicals tomorrow if it makes it through the night. I was thinking maybe something caught in the pump, or air pocket. I will keep everyone posted. Thanks again. Quote Link to comment Share on other sites More sharing options...
Jersey Hot Tub Repair Posted December 13, 2017 Report Share Posted December 13, 2017 An air pocket is very common after draining. It may have worked it's way out. Dave Quote Link to comment Share on other sites More sharing options...
Tbstanford Posted December 13, 2017 Author Report Share Posted December 13, 2017 Thanks for the help. I was pulling my hair out. I hope you are correct. It's good to know that an air pocket is a real possibility. I was just guessing/hoping that was the problem. Tganks again. More to come tomorrow.
