I just hit the button again. It doesn't seem to push in, but I pushed as hard as I could. Should I feel/hear a click or something? I just checked my control panel. I only have one light, which is POWER and is a steady red. There are no other lights on my control panel. I have 4 lights in my control box (LIM OK (steady green), HTR (steady red), Unplugged (not on), and FLOW (steady red). Does this help with anything? I guess I should have just made an appointment with the dealer so I can get on their list. I just know that everything was working fine before I grained it and replaced the filters. I guess thats what I get for trying to do the right thing!
-Thanks

You're going to need to OHM out the heater, and check for volatge going to the heater.

Unplug the heater leads from the control box, and check resistance. If you get O/L, bad heater. Try really mashing that button again for all you're worth, and OHM out again. Should be between 9 and 11 OHMS.

Double check voltage as well, should be 220v on the 30 amp breaker. Be sure to meter the hot leads together, not one at a time, to get 220v. A bad heater breaker (30 amp) also fits your description of issues, as well as a bad T-92 heater relay (18v dc coil)

Also, once the Hot tub has reached temp, you should see a green "ready" light appear on the control panel, oright next to the red power light

I'll give it a try. Thanks again

called the service guy. I found out that the heater had ben replaced and that the red "button" I have been pushing is indeed a sticker. He told me the original heater had the reset button in the same spot as the red sticker. The reset is on the backside. He reset it and it is working fine now. Now I know, but thanks for all your help! I really appreciate it.
