Hi all,
I have a Pentair 400 heater and the Pentair EasyTouch system and the whole package is about 10 years old. Everything has been working great, except the heater started having issues this last year. I finally had the time to dive into troubleshooting things as I am furlough due tho this covid thing.
I did a bunch of searching on the web and on this site, and decided to take apart the manifold, proactively replace the bypass valve, clean out the manifold, install a new thermostat, and a new stack flue sensor (due to an intermittent E06 error). Put it all back together and the heater purrs like a kitten. Heats great - right up to 90, then shuts down.
I verified the EasyTouch temp sensor is within 1-2 degrees of a real thermometer 1 foot or so under the pool surface. The last time I used the spa, 2 years ago, it heated up to 100 no problem.
Any ideas what the issue could be? Where I can start look looking?
Thanks in advance!!
