“FV-SENSE” and “OPEN” Flashing
Flammable Vapor Sensor is open
1. Check all wiring to the ammable vapor
sensor.
2. Remove the connectors from the
ammable 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
ammable 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.

“FV-SENSE” and “SHORT” Flashing
Flammable Vapor Sensor is
shorted
1. Check all wiring to the ammable vapor
sensor.
2. Remove the connectors from the
ammable vapor sensor and measure
the resistance of the sensor with an
ohmmeter.
A. If the reading taken is less than
2000 ohms, replace the ammable
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.

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 – the
upper control should be replaced.

“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
lled with water. Water must ow from
the hot water faucet before turning “ON”
gas to the water hea
ter.
