Thanks, to be clear, no recent construction....just the way the spa fills up, it overflows into the pool..... Busted there on the cya reading....didn't get to it but will test it tomorrow. Regarding the ph reading, so you'd recommend adding acid to lower it down even further? When you say low...

Hey gang, Got my TF-100 kit earlier in the week and have been itching to test my saltwater 25,000 gallon concrete (gunite??) pool....... Here we're my results as of today: Ph 7.8 (good there). Salt 3600 (although the internal panel says 3500). FC 6.5 (lots of aeration due to spa fill...

Thanks for the tip bugman, unfortunately, I had tried that at first with same outcome. It was definitely root caused as the thermistor with a successful replacement. Good tip though.

Been lurking on here for a few months, registered earlier this month for some help... this site has been awesome education with great support... .here is a pic of my little slice of heaven in Flower Mound Texas!

YES it is! Listen to this guy's luck....I walk into Leslie's pool supply asking for the thermistor...he didn't have in stock but the store 45 minutes away did....so I take a gamble and drive over, pickup the $112 thermistor...bring it back, plug it in the control board without actually...

Thanks again Paul. Appreciated all the help. I found the thermistor on the other side as you noted. Black/red/blue wires twisted together and run from the control board over to the thermistor. But, here is where it gets interesting..... The way my h400 is wired, it's Setup for external...

Thanks Paul. Ok, have two of them. Top has purple and blue wires. Bottom has purple and red. Purple appears to just be a jumper between top and bottom sensors. So those need replacing? Both sensors?

Hey gang, quick update here.....spent the morning cleaning all the connections and doing circuit tests with a multimeter. All checked out clear. After the hard reset, all error codes are gone and the heater actually fires up!,,, blower kicks in but a second later, I get the SF and HS error...

Thanks Jill....seems like its normal cost around here in Texas.....checked with co-workers and they are all paying about the same rate......still planning on cutting the cord after he does my DE filter service......wish me luck!

Thanks Paul. Problem is I can't even find someone that wants to work it. Most just want to replace with a new unit. Any idea where to begin troubleshooting? Control board error code isn't being displayed but maybe it is the issue?

Popped open the cover, cleaned all connections... still the same.. nothing fires off... looks in good shape on inside... here are pics.

Pump is on (variable speed - 2500 rpm) with water flow through heater. Minimum for this heater is 25 gpm so I assume pump is pushing enough flow. I even tried at max speed (3100 rpm) and still same result. The heater is installed after the DE filter and right before the return line back to...
