SOURCE: Paloma PTG 74PVN Tankless Water Heater

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

SOURCE: Tankless water heater (Paloma) Has C2 11 error

I had this problem with the C2 11 error code. My unit is 1.5 years old. I called Paloma and they emailed me an 11 page document to clean the burners. I am not an HVAC but I got the feeling that's who the instructions were for. Very difficult but you can do it if you're handy. You basically take apart 1/2 the unit, be carfull not to lose any screws and label all the little brackets that come off. It took me 2-3 hours to get to the burners. I used a can of air (for keyboards-electronics) to blow on the burners and clear any build up. After putting it back together (carefull to make sure the 3 gas tubes make a seal when re-installed) the unit works. I did this today so I'm not sure the unit will still work in a week/month. I am dreading having to do this every year to keep the unit running.

SOURCE: Paloma tankless, gas, water heater, error code C7 76

If you look on the left hand side of the burner control module you'll see 4 capacitors - the capacitors have most likely failed...pretty sure anything code 76 is P/S failure. It may also be covered for manufactures defects. If the cap is blown..the top will be slightly raised as apposed to flat like the other nearby caps - they are called top blow capacitors...the damage should be evident.

Rheem Paloma tankless computer? No error code? One possible cause; Crossover caused by bad single handle faucet cartridge drawing cold water into line causing shut down of tankless burner?

I have a paloma tankles water heater model #ptg-42pvn i am getting an intermitent error code C4,12. what is the problem?


Copy following link for Rheem-Paloma tankless troubleshoot and error codes:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://waterheatertimer.org/How-to-install-gas-water-heater.html#install

If unit worked before: Maybe bad PC board. Maybe lack of required yearly maintenance.
Common error codes can be caused by not following maintenance protocol such as cleaning combustion parts, checking gas pressure, checking venting, and air intake, bleeding gas line etc.
Too bad Rheem-Paloma manuals do not show HOW to conduct this maintenance, leaving customer with many unknowns, and no way to oversee that maintenance performed by hired technician is complete, and matches recommended maintenance.
Sell unit on ebay, and install tank-type gas water heater.

Thermostat flashes IL ? Model PTG-53PVN


http://www.palomatankless.com/owners/homeowner+trouble.lasso#28-11
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.

Paloma tank less water heater flashes code C4 13 and we have no hot water?how to fix it?


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.
