PROBLEM
The air pressure switch contacts remain open longer than 5 seconds after the combustion fan is energized.
Flammable Vapor Sensor is open
SOLUTION
4.System must be manually reset by entering a special FVS reset sequence into the Electronic
Control Display. See Electronic Control
Display - FV - Sense Reset Sequence in the Kenmore PCC Water Heater Service Handbook.
1.Clean the screen on the combustion air intake chamber, retest.
2.If the problem persists: Cycle power to the water heater "OFF" and "ON" to reset.
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 more than 1.7 million ohms, replace the
flammable vapor sensor.
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.

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 morethan
2000 ohms, and the wiring from the control to the sensor is good, replace the lower control.
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.
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.
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 - the upper control should be replaced.
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.
1.Turn the power offfor 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.
