Perhaps I’m missing something. I’m looking in the hole that the thermal regulator goes in (with spring for that removed as well). The picture attached is of that hole. All I see is the hole where the thermal regulator sits.See the video. If you don't see the disk, do you see a hole?
If you push on the spring, you should see the disk moving in the hole where the thermal regulator goes.
Ok, finally got access to water inlet (see attached picture). It's really tight in there but when I pushed down on spring with a screw driver, I did not see anything where the thermal regulator goes. Any more thoughts? And, thank you again for all the assistance.Look in the water inlet. Push down on the spring and you should see the disc get pushed into the hole where the thermal regulator is.
Ya, that's what I'm thinking. Just ordered a new kit and plan to take everything apart over the next two days. If that is the final solution, I'll be happy but this has been a journey! Thank you again. I owe you a few beers, at a minimum.Did you watch the video?
If you're not seeing the disc getting pushed into the hole where the thermal regulator goes, then it probably broke off.
If you look at the spring in the picture you can see the shaft running through the center of the spring. Does that mean that it's not broken as the spring is somewhat still compressed just like the youtube clip demonstrates.Ok, finally got access to water inlet (see attached picture).

Cool, thanks again. I'm going to go ahead and take it all apart to see what's going on. A new kit has been ordered and will be here tomorrow. Will report back!The thermal regulator reduces flow through the heat exchanger. So, it makes sense that it would work with it out.
The internal bypass doesn't bypass all of the water.
I think that the internal bypass is probably bad.
If the plunger has broken off, it's probably going to be in the plumbing somewhere.
Can you see the hole where the plunger should go?
It's really hard to see exactly what is going on so I think I'm going to go ahead and take it apart to find out.If you look at the spring in the picture you can see the shaft running through the center of the spring.

I'll try to look again but it's really hard to see in there. And, too small a hole and too long a shaft to feel in there...When you look into the hole where the thermal regulator goes, you should be able to see the plunger disc or the hole that the disc covers.
Can you see the hole or feel it?
Thank you! Going to put this back together and fire it up to see what happens. Next comes cleaning the DE Filter Grid and looking to see if any grids are damaged. Where is the heat exchanger and should I check there for stuck debris?That looks like part of a de filter grid. You need to take the filter apart, clean the grids well, replace any damaged grids and recharge with DE.
Since there is debris getting to the heater, there might be debris stuck in the heat exchanger blocking water flow.
Scale can also reduce water flow through the heat exchanger and reduce heat transfer.
Overheating water is more likely to scale.
In any case, if the internal bypass plunger is stuck open, that can cause the problem.
The gap seems a little bit small to create the problem, but it's possible
Let's see what happens when you get it put back together.
Make sure that the flow is good.
Thanks again. Heater is back on and working for now. Time to clean the filters and see what's going on there.
This is basically the same heater. You can see the holes going into and out of the heat exchanger when you have the manifold off.
There's no easy way to check in the heat exchanger for debris.
Maybe blow air through the tubes to see if anything comes out.
