There is a piece of clear plastic film wraped around the heat exchanger. Conductive material (black) is coated on that film. In case of overheating, the film melts, break the circuit and the heater stops. That's how it works, in theory. I had the same problem and had to remove the heat exchanger to inspect the film on the back side. It's a pain in the @#$%, especially found no problem with the film itself. This is what you should do: Find and disconnect connector U in the center of the board with 2 tiny white wires. Measure resistance between those 2 wires, should be 50K~100K. If it's open, either the film is damaged or, in my case, the connector on the film is bad (on the right side of the heat exchanger). Since no other tankless maker uses this protection scheme, I don't think it's doing much. My solution is to fool the controller with a 100K ohm resistor across the 2 white wires. If you're not comfortable with my micky mouse solution, replace the film.

I am certain that the 100 ohm resistor would work perfectly, but since I wanted to take a hot shower tonight, I simply used the half of the film that was remaining by Drilling a screw through it and vent racing the Black Ink about halfway through and drilling another screw through it. A range of 50-500 ohms is significant so even a small piece of remaining film should provide the necessary resistance.

I followed these already posted directions, found the thermal film melted and could not really trace the wires from the board to the film. I went straight to the film connections pulled the wires from it and spliced in the 100k,1/4 Watt R between the two white wires...... and i am back in hot water. Gotta love the net!

Hi Gizmonix I did your 100 ohm resistor bypass trick to get around a damaged plastic film and the darn tank still flashes 14 -0 Any other ideas what I could check to fix this?

    Sorry, After putting on my glasses (cough,cough) I realized there was a k on the end of that resistor value. I found a 100k resistor, put it inline and BAM! The water heater works again and its nice and clean now too. Thanks a Million gizmonix Now where can I order a new plastic film fuse?

Even though you are not getting an error code, there are may be some diagnostics in the controller that can identify whether it's an electronic (controller/sensor) or a heat exchanger issue. I would contact Rheem tier-2 support.

What does code 36 mean


Error code 36 does not show in Rheem tankless manuals.

Copy following link for general troubleshoot and error codes, and Rheem contact information:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Error code 36 does not show in any resource, including 2008 service manual, or 2012 product manual.
Check that remote control display is illustrating the correct number.
For example there is error code 35.

The Controller displays error code "1L."
There is a build-up of lime in your Paloma.
Contact your plumber to service the Paloma by flushing out the lime.
Also search u-tube for flushing lime out of tankless.

I have a paloma ptg-74pvn and the digital temp. display keeps shu


How reliable is your AC? With the digital r/c connected, every time the heater recovers from power outage it's in the OFF default state. If you can not fix the power issue, disconnect the remote control. The w/h will recover in the ON state.
