Question about Rheem Paloma Tankless Water Heaters PTG-74PVN Tankless RTG-74PVN
Rheem, Richmond, Ruud, and Paloma are all the same manufacturer. After about 9 months, my tankless RTG-74PVN started giving me error code 11 and cold water!. I fixed it by cleaning the burner, as shown in this video:

That error code means not enough gas.
however, there might be something going on with your venting. it could be sucking exhaust air back into the unit. this will cause the same error code.
if your problem is intermittent, then I would suspect the venting to be the issue.

I have the exact same problem with error code 13 on my Rheem/Ecosense 180dvn . The unit ran good for at least a year, and then I started getting the same error 13 every few minutes. I called the Rheem service department, and they told me to check the vent installation as well as the gas pressure. I reinstalled the vent with new seals. I only have about 6 ft of vent, so there should be very little resistance. I checked the gas pressure, and it shows 9 in H20 pressure, which is well in the range recommended. The service center scoffed at the suggestion that it could be their circuit board. I am totally at a losss and at the verge of ripping this very expensive installation out of my attic.
