    Pentair MasterTemp 400 HLS intermittent error

    Yeah if that is the only next option (reading the Further Reading, that was all it suggested), then I'm going to call a service company. I saw a thread with pics about taking apart the heater manifold and not really something I want to get into, especially if that's still not the issue. Is it...

    Pentair MasterTemp 400 HLS intermittent error

    I ordered a new regulator that came in today. I tested it and it did not open until 140 degrees. It also did not have a rating stamped on it. It is supposedly a pentair original part but a lot of people have complained that they aren't the correct part, so that wasn't a surprise. I took the...

    Pentair MasterTemp 400 HLS intermittent error

    I may not have been clear. The regulator seemed to open fine. My hot water is only 110, so I had to boil some water to add to test it. At 125 it opened which could just be a thermometer discrepancy. At 130 it clearly was opened all the way. If you think I should have seen some movement before...

    Pentair MasterTemp 400 HLS intermittent error

    I read through a bunch of posts including the massive "Further Reading" page about Pentair heaters and I'm still stuck. Our heater is plumbed for both our pool and in-ground spa, so we went to last night and I turned on the heater to get into the hot tub, and ran into an odd issue. The heater...

    Thoughts on Diagnosing Mystery Leak

    Also, I just re-checked the pool skimmers. both of them seem to have hairline stress fractures, but they don't seem to be cracks all the way through and there's no give to the plastic, so not sure if these could be the cause. Can't say if I have ever noticed these, but the skimmer was...

    Thoughts on Diagnosing Mystery Leak

    Yes, there is a equalizing line between the pool and spa. When I shut off the spa schedule, I sealed that line to make sure the 2 didn't have any way to interact. The spa skimmer had cracked last year, so I used the pool epoxy/putty to seal it when I opened the pool. I assumed that was the...

    Thoughts on Diagnosing Mystery Leak

    In-ground pool, in-ground spa. Same equipment, but the plumbing in and out for both are separate, so I can either run the pool or run the spa. I have it set to run 24/7 for the pool with a 30 minute cycle for the hot tub each evening. Symptom: Water level in both spa and hot tub drops quicker...

    Additional troubleshooting help for my SWG

    Just an update...I watched it last night and caught it while it was back on, so it is cycling like it's supposed to. It doesn't seem to be 180 or 120 minute cycles, so not sure what it is. It's definitely not 60 minutes, so maybe 90 minute cycle. Just goes to show you can still learn something...

    Additional troubleshooting help for my SWG

    Thanks, that helps. so it says the AquaRite is 180 minute cycle, and 120 minutes prior to firmware 1.55. I'm running v1.4, so if I read the post correctly, it is at 120 minutes. So at 25% it should run for 30 minutes, then stop for the other 90 minutes. if it's 180 minutes total, it should run...

    Additional troubleshooting help for my SWG

    You're saying if it's at 100%, it's always generating, and if you have it on 50% it cycles on/off every ~30 minutes? I've never noticed that, but that would explain the behavior i'm seeing. The only reason I was alarmed at this behavior was because the last time it did this, it never cycled...

    Additional troubleshooting help for my SWG

    Yep, that's the article i reviewed after I replaced the thermistor and still had issues. Also looked through past posts and couldn't find the same issue I'm seeing. I timed things...I can set it to "auto" and it will turn on and run and sometime between 20 and 30 minutes it shuts off. Still says...
