Anleitung Zusammenfassung


B. If the reading taken is less than 1.7 million ohms, and the wiring from the control to the sensor is good, replace the lower control. 12. “FV-SENSE” and “SHORT” Flashing Flammable Vapor Sensor is shorted 1. Check all wiring to the flammable vapor sensor. 2. Remove the connectors from the flammable vapor sensor and measure the resistance of the sensor with an ohmmeter. A. If the reading taken is less than 2000 ohms, replace the flammable vapor sensor. B. If the reading taken is more than 2000 ohms, and the wiring from the control to the sensor is good, replace the lower control. 13. “THMSTR” and “OPEN” Flashing The self-diagnostic test has detected the temperature sensor (thermistor) inside the immersion probe is open. 1. Turn power off for 10 to 20 seconds then on again to clear this error code. 2. This part of the control cannot be replaced or serviced. If the error code cannot be cleared, the lower control must be replaced. 14. “THMSTR” and “SHORT” Flashing The self-diagnostic test has detected the temperature sensor (thermistor) inside the immersion probe is shorted. 1. Turn power off for 10 to 20 seconds then on again to clear this error code. 2. This part of the control cannot be replaced or serviced. If the error code cannot be cleared, the lower control must be replaced. 15. All Segments Flashing The self-diagnostic check has detected one or both of the temperature adjustment buttons are stuck. 1. Press and release each of the temperature adjustment buttons. If the above action does not clear the error, the control will continue to regulate the water temperature at the last setting. However, settings will no longer be adjustable – theupper control should be replaced. 16. “P-ANODE” and “OPEN” Flashing No current to Power Anode. 1. Check the wire that runs from the power anode to the upper control. Check the wire for damage, and to ensure that the connectors are fully seated into the mating connectors on both ends. 2. Check that the tank is full of water. Never use this water heater unless it is completely full of water. To prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” gas to the water heater. 3. Cycle power to the water heater “OFF” and “ON” to reset. 17. “P-ANODE” Flashing Power Anode circuit failure. 1. Turn the power off for 10 to 20 seconds then on again to clear the error code. 2. If the error code persists or cannot be cleared, replace the upper control. 22 TROUBLESHOOTING FLOWCHART Please Note: The control continually monitors internal circuits and external sensors. Error codes noted above, and those for self-diagnostic faults can be found on pages 20 through 22. APPLY POWER TO APPLIANCE YES REQUEST FOR HEAT PRESENT?

NOTE: If the water heater is located in an area that is subjected to lint, pet hair or dirt, it may be necessary to check the air intake chamber screen more frequently. • Use a vacuum cleaner with a hose attachment to remove any dust or debris that may have accumulated on the screen. Air Intake Chamber Screen Figure 24. Cleaning the Combustion Chamber and Air Diverter Assembly: • Follow procedure outlined in “Removing Inner Door/Manifold/Burner Assembly”, page 41. • Use a vacuum cleaner/shop vac to remove all loose debris in the combustion chamber. Use compressed air to clear any dust or debris that may have accumulated on the air diverter assembly. • Reassemble following the procedure under “Installing Inner Door/Manifold/Burner Assembly”, page 42. Figure 25. INNER DOOR/ MANIFOL...
