    I turns out that it was a universal problem with certain Rheem/Paloma water heaters. They were long aware of the issue and left us owners in the dark for a while, in my case it was for nearly a year; given the importance of the machine, I will not forgive them for such service.

    The solution was the circuit board. They sent me a replacement (overnight) with sketchy instructions. After swapping out the circuit board, I called there tech. department and the technician guided me through the reprogramming which took approximately 3 minutes. It has been a week and a half and so far no issues -- I am keeping my fingers crossed!

Did you check the filters on the the water valves, i am not exactly sure about your codes that are shoeing but if you could read it and post them, i know on some of the units 76 means there is low water pressure and the filters are behind 2 caps one on each side above the shut off valve take off the caps and remove the screens, clean them and replace them ,, make sure you turn off the water on both side first or you will get wet

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.

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.

My paloma tankless water heater will shut off in the middle of a shower


I am not sure if this is it but I had mine at too high of a temperature therefore I was not using enough volume of hot water to keep the heater on. They have a minimum amount of flowrate to sustain. Try turning the water temp down to 125-130. Hope this helps

C8 is the last stop in the point of burner ignition and a total of eight error codes. Error code 12 is a supplemental code that means your LP gas supply is too low...have your LP tank service and try again.

I have a paloma tankless water heater about 3 years old model PTG-74PVN and it works for 2 minutes and shuts off with error code C4 and 13 flashing. (City water pressure is fine)Can anyone help? Thanks...


I had the same problem with my Paloma a year and a half after installation...contacted Rheem customer service (800-432-8373) and they recommened a local installer in my area. The technican diagnosed the problem as the "flow control valve"; he managed to get Rheem/Paloma to cover the part under warranty...I only had to shell out the money for the install.
