    What to do if my HTP EL-80 Boiler displays Fault Code F09?
    • A
      Aaron MillerAug 22, 2025
      If your HTP Boiler shows fault code F09, it means the boiler attempted to ignite four times during a single heat call but failed. Here's what to do: 1. Check for a spark at the igniter through the observation window. 2. If there's no spark, ensure the spark electrode gap is properly set to .196” (5.0 mm ± 1mm). 3. Remove any corrosion from the spark electrode and flame rectifier probe. 4. If there is a spark but no flame, verify the gas supply to the boiler. 5. If there is a flame, inspect the flame sensor. 6. Inspect for any flue or condensate blockages.

    What does Fault Code F13 mean on my HTP EL-80?
    • L
      lsimsSep 5, 2025
      If your HTP Boiler displays fault code F13, it indicates the fan isn't running at the commanded speed. Here's how to troubleshoot: 1. Check the combustion air fan wiring. 2. Measure the DC voltage from the red fan wire to ground while connected to the fan; it should be between 24 to 40 volts. If lower than 24 volts, check for excessive external loads on the boiler sensor terminals. Disconnect the 5-pin plug from the fan and check the voltage on the red wire again. If it's now between 24-40 volts, replace the fan. If it remains below 24 volts, replace the boiler control board.

    What does Fault Code F03 on my HTP EL-80 Boiler mean?
    • T
      Tracy WhiteSep 3, 2025
      If your HTP Boiler is showing fault code F03, it indicates that the return temperature sensor of the boiler has failed. Here's how to troubleshoot: 1. Check the circulator pump operation. 2. Ensure adequate flow through the boiler by accessing the status menu and verifying that there is less than a 50°F rise from the return thermistor to the supply thermistor. 3. Troubleshoot the thermistor.

    What does Fault Code F02 mean on my HTP Boiler and how do I fix it?
    • M
      Monique GreenSep 2, 2025
      If your HTP Boiler displays fault code F02, it means the supply temperature sensor of the boiler has failed. Here's how to troubleshoot: 1. Check the electrical connection to the thermistor on the outlet manifold. Verify 5 VDC by checking in the Molex connector. If there is no 5 VDC, check the harness. If the harness is OK, replace the control. 2. Replace the thermistor if necessary.

    What does Fault Code F06 mean on my HTP Boiler?
    • B
      Bruce BridgesAug 31, 2025
      If your HTP Boiler is displaying fault code F06, it means the return temperature of the boiler is excessive. To resolve this: 1. Check the circulator pump operation. 2. Ensure adequate flow through the boiler by checking the status menu to confirm less than a 50°F rise from the return thermistor to the supply thermistor. 3. Verify the direction of flow on the boiler circulator. 4. Troubleshoot the thermistor.

    What does Fault Code F05 indicate on my HTP EL-80?
    • B
      Brett BrooksAug 30, 2025
      If your HTP Boiler shows fault code F05, it means the supply temperature of the boiler is too high. Here’s how to troubleshoot: 1. Check the circulator pump operation. 2. Make sure there is adequate flow through the boiler. Access the status menu to ensure the temperature rise from the return thermistor to the supply thermistor is less than 50°F. 3. Verify the direction of flow from the boiler circulator. 4. Troubleshoot the thermistor.

    What does Fault Code F00 mean on my HTP EL-80?
    • T
      Taylor LeeAug 27, 2025
      If your HTP Boiler is displaying fault code F00, it indicates the water in the boiler has overheated. Here’s how to address the issue: 1. Verify the circulator pump is functioning correctly. 2. If the pump is running, ensure there is water in the system and it's circulating properly. Check that all ball valves and zone valves are correctly opened or closed. 3. Observe the temperature/pressure gauge. If the water isn't excessively hot but the message appears, inspect the wiring to the water ECO sensor and repair if needed. If the wiring is fine and the code persists without overheating, replace the ECO sensor.

    How to fix Fault Code FLU on my HTP EL-80 Boiler?
    • H
      Heather KellerAug 27, 2025
      If your HTP Boiler is showing Fault Code FLU, it means there's excessive flue pressure. Here's how to address it: 1. Make sure that the flue is not blocked. 2. Check the switch wiring by applying a jumper in place of the switch. If the code clears with the jumper in place, replace the flue switch and connect the wires to the new switch before running the boiler.

    What does Fault Code F01 mean on my HTP EL-80 and how do I fix it?
    • C
      Christopher SchwartzAug 26, 2025
      If your HTP Boiler displays fault code F01, it means a safety interlock switch has tripped. Here's how to troubleshoot: 1. Check if an optional UL 353 LWCO is installed. 2. If so, see if the indicator light shows the LWCO has tripped. 3. If tripped, restore the water level and manually reset the switch and boiler. 4. If there are no optional switches, use an ohmmeter to test each standard switch after turning off the boiler and disconnecting the switch to be tested. Find the tripped switch and investigate the cause, considering that temperature switches often trip due to low water flow or poor heat transfer. 5. If no switches are tripped, push RESET on the boiler. If the F01 code returns after a short run, check the flue for blockage.

    What to do if my HTP Boiler shows Fault Code F10?
    • L
      Laura MasseyAug 25, 2025
      If your HTP Boiler displays fault code F10, it indicates the flame was lost three times during one demand call. To address this: 1. Monitor the gas pressure to the boiler during operation. 2. Make sure the flame remains stable once lit. 3. Confirm the display changes from “GAS VALVE ON” to “RUN” shortly after ignition. 4. Check the FLAME signal on the status display; it should exceed 1.0 when firing. 5. If the signal is below 1 microampere, clean the flame rectifier and spark probe. 6. If the issue continues and the ‘FLAME’ signal remains below 1.0, replace the flame probe and spark igniter probe. 7. A stable flame signal should read 5.0 to 9.0 after a minute of firing. If unsteady, inspect the burner and its sealing gaskets.
