Thanks again Swine for the thermister problem. Now the problem is where do the thermisters plug in? It seems where these two were plugged in are not original. One is glued or epoxied into the filtetr compartment. I thought it was screwed in, but it was glued in instead. The other was connected to the outlet side of the heater,but the thing I pulled out is about twice the diameter of the new one. Could this be a flow switch or possibly a new design? Where could I find any type of schematics for this tub? (plumbing and electrical) Thanks for any help...........Steve

Take a pic- that doesn't sound right...

Heres a pic of the filter box and where the thermistor was put. It was glued in.............

The last pic was the discharge side of the heater. This one should be of the filter box where the thermistor was glued in.

Obviously that system's been modified for a different heater.

Cute mod.

Take a photo of the entire cabinet internals from about 6" off the ground. This would be interesting to see.

Heres a pic of the entire box as I bought it. Got a steady red light and all the pumps work as well as the clean cycle. I guess it will take a while to see if this thing heats up. Any advice as to where to reconnect things would help gteatly as well. Thanks, Steve

Lol... that's a D1 heater.

Glad you find the heater amusing. I have never owned a spa and just wanted to get one to see if we would use it. I have it up and running, but now I dont feel very comfortable about the heater. Can I get the heater that is supposed to be on it? Will it have the correct size holes for the thermistors?

Sorry for my amusement (at your expense) - I've been busy and hoping that Swine would reply tonight. I'll get back to you on this tomorrow (if he doesn't first).

Thanks for the photos, they've helped a lot!

SWWWEEEEEETT!

Is it working?

I don't really know what to say, other than, "why?"

There's a few problems, but as long as you put your fingers in the water before jumping in (In case it has gotten too hot), you should be OK.

Oh, and when your circ pump eventually fails, things will get interesting. The temp sensor isn't on the heater output, it's on the circ pump intake.

I have no idea why someone popped in a D1 heater instead of the Hot Spring heater, but if you plan on keeping it, you should ditch the D1 heater, and get the Hot Spring one, and then fill in the hole in the shell.

Ordered a new heater last night. also found an exploded view of the pump and could see where the sensors fit as well. Looks like it "fits" much better as well. I have a floating thermometer in the tub as well, and always will. Thanks for the help and I should have the new heater by the weekend so I can replace it. Thanks for the advice.
