Error codes for Paloma Tankless Water Heater

Paloma is a manufacturer that makes a variety of water heaters. Paloma produces a number of different types of water heaters, including tankless water heaters. Tankless water heaters use water that is heated by using the pressure of water that is drawn from the ground or from a municipal water supply.

Tankless water heaters are easy to install, but they do have some disadvantages. One disadvantage of having a tankless water heater is that it can be difficult to maintain, and it is possible to create numerous error codes when you try to service your heater. It is easy to get error codes that are associated with tankless water heaters. Then we will provide some advice on how to fix them.

11 (No Ignition)

Ensure that the gas supply lines, gas meters, and regulators are sized correctly. Check that all electrical connections and devices are properly grounded. Check the gas valves to see if they are open or if there are any problems with the gas valves. Check that the igniter is properly working. Check the wiring that connects to the igniter to ensure that it does not have damage.

14 (Overheating Wrap Fault)

Ensure that the high and low pressures that the firebox is able to release are correct. Check the gas type of the unit to ensure that it is compatible with the gas that is being used. Check the heat exchanger for any cracks or separations.

  1. 72 (Flame Sensing Device Fault)

Check that the flame rod is touching the flame when the unit is preparing to fire. Check the inside burner for foreign matter that may be blocking the flame at the flame rod. Check the wires that attach to the flame rod for damage. Check that the flame rod is connected to the correct circuit and that it has the right voltage.

Take out the flame rod to clean it and clean off any ash that may be in the flame rod. Flame rod needs to be replaced.

10 (Air Supply or Exhaust Blockage)

Check that all vent components are connected properly. Check that there are no obstructions that are blocking the flow of air into the flue or exhaust.

No Code Error

Nothing happens when water flows through the water heater. Check that the unit is connected to a power source that is working properly and that circuit breakers are on. Check power supply fuses to ensure they do not blow. Ensure the water supply is running through a clean filter in the unit.

Check that the water is flowing at least the minimum speed that is required to cause the unit to fire. Check for any pipe that may be leaking into the water control unit. If the unit is new, make sure that hot and cold water lines are not crossed. Check if the unit is causing water to bleed over (Close cold water supply valve to water heater).

Open hot water supply to fixtures. If you have water that flows continuously from hot water taps, it could be that the system has a bleed over problem.
