If the Water Heater lockout condition has been identified by 3 or 5 flashes, the lockout must be cleared by
turning the dc power 'off' and then 'on' again at the master switch in the vehicle. The Water Heater must be in the

lockout still will not clear (identified by a solid LED or all bars lit), please press the red Reset Button on the Water
Heater once (see Fig. 28).
If the Water Heater lockout condition has been identified by 1 or 2 flashes, the lockout must be cleared by pressing
