Resetting The Heater Control
• Soft lockouts as diagnosed by the system error
codes require the gas control to be reset.
• To reset the control, slide the "ON/OFF" switch
to the "OFF" position. Wait for 10 seconds and
move the switch back to the "ON" position.
• If the problem that caused the control to lock out
has not been corrected, the control will remain
or again go back into lockout.
Lockouts
Soft Lockout
occurs when a system safety device trips to
break the sequence of operation. The control
will retry the system in a timed basis but will not
reinstate operation until the failure is corrected.
Hard Lockout
• occurs when the main controller fails and must
be replaced.
The gas control valve\thermostat includes a
temperature limiting ECO (Energy Cut Off) system
that will shut off the water heater if the water
temperature is too high.
Should the water temperature get too high, the
diagnostic status light will indicate a code (4
flashes), indicating an over-temperature condition
and the main burner will be shut off. If a high
temperature condition occurs, turn the main gas
supply OFF and have the water heater repaired
by a qualified service technician. Contact Sears
