    What does error code Er:72 mean on a Westinghouse WBRCNG140F Boiler and how to fix?
    • C
      Christina GardnerSep 16, 2025
      This Error Code Er:72 will disappear when the condition is remedied. If the error happens again: 1. Check the boiler cover, ensuring it is secure, as the flame detection sensor can detect an external light source. 2. Check the flame detection sensor, ensuring connections are secure. Normal operating settings are more than 2.5DC before ignition, less than 2.5DC after ignition. 3. If the problem persists, replace the main control.

    What to do if Westinghouse WBRCNG140F has no water when faucet is opened?
    • J
      Jonathan MillerAug 26, 2025
      Check if the water supply valve is shut off at the meter and open it if closed. Also, verify that the water supply valve near the unit is open. If the water pipe is frozen, turn OFF the unit, close all water valves and the gas valve, and contact an authorized service technician. If an error code is flashing on the display panel indicating a leak, contact an authorized service technician.

      Melanie HardySep 17, 2025
      This Error Code Er:76 will disappear when the condition is remedied. If the error happens again: 1. Check the connections from the main control to the display panel (this error occurs if there is no communication for ten minutes). 2. If the problem persists, replace the display and/or the main control.

    What to do if Westinghouse WBRCNG140F displays error code Er:11?
    • A
      Anthony RobertsDec 1, 2025
      If the Westinghouse Boiler displays error code Er:11, first, press the Power button to clear the error. This code will also automatically reset after one hour (up to three times). If the error persists, follow these steps: 1. Monitor the gas pressure to the boiler while in operation, ensuring it remains between 3.5 and 14” WC. 2. Check the gas valve wire and flame detection sensor, ensuring the connections are secure. Normal operating settings for the flame detection sensor are more than 2.5DC before ignition and less than 2.5DC after ignition. 3. Check the igniter transformer for proper connection. 4. Clean the spark igniter with steel wool to remove oxides, ensuring proper separation (3-4 mm). 5. Replace the spark igniter if damaged. 6. Ensure that the flame is stable when lit. 7....

    Why does my Westinghouse WBRCNG140F display error code Er:37?
    • D
      Diane GrossSep 8, 2025
      Error code Er:37 means the supply frequency is too high to operate. This Error Code will disappear when the supply frequency returns to normal operating range. If the error happens again: 1. Ensure the boiler is properly wired to a power source meeting the requirements on the rating plate. 2. If the problem persists, replace the main control.

    • B
      banksjamieSep 3, 2025
      This Error Code Er:35 will disappear when the exhaust temperature decreases. If the error happens again: 1. Check the exhaust temperature sensor, ensuring the connections are secure. 2. Check the sensor resistance; if resistance is zero, replace the sensor. 3. Check the exhaust vent for any blockage. 4. If the problem persists, the main control may need replacement.

    What to do if Westinghouse Boiler displays error code Er:20?
    • B
      Brian JenningsSep 1, 2025
      If the Westinghouse Boiler displays error code Er:20, press the Power button to clear it. If the error happens again: 1. Check the condensate and main controller connections to ensure they are secure. 2. Check the condensate resistance; if the resistance is not zero, replace the switch. 3. Check the condensate hose to ensure it is connected and in good condition. 4. Check the condensate line and termination for blockages. 5. Check the exhaust vent for blockages. 6. If the problem persists, the main control may need to be replaced.
