Normal Operation; Error Codes - Electrolux EN18WI30LS Service Manual

< How to Use >

1. Normal Operation

(Hot Water Production)
1. Turn on the POWER by pressing the "POWER" button on the remote controller. (The priority lamp lights.)
2. Whenever a hot water fixture is opened, or an appliance that requires hot water is turned on, as soon as the
flow sensor detects at least the minimum flow rate required for initiating combustion, the fan will initiate and
pre-purge any residual combustibles in the combustion chamber. The igniter will then create a spark and the
gas valves will open, alllowing fuel into the combustion chamber where it will be ignited by the spark.
3. When the flame rod detects a flame, the igniter stops sparking.
4. The computer will then control the gas and water control valves to maintain the water at the temperature
set on the remote controller. The temperature can be adjusted using the "Setting Buttons" on the remote
controller.
5. When the demand for hot water ceases, the unit will stop heating:
When the flow sensor detects that the flow rate has dropped below the minimum rate for continued burning,
the gas valves will close and the burner flame will go out. After the post purge removes residual gas from the
combustion chamber, the unit stops.
If necessary, turn off the power by pressing the "Operation Button" on the remote controller (the priority lamp
will turn off).

2. Error Codes

If the flame rod does not detect a flame, or if the high limit switch has been triggered, the gas valves will
close, the flame will go out, and an error code will flash on the remote controller.
In order to reset the unit and remove the error code, turn the power off by pressing the "Operation Button" on
the remote controller, and then press it again to turn the unit back on.
If the problem requires service (the thermal fuse is triggered, etc) the gas valves will stay closed and resetting
the unit will not eliminate the error code. If this is the case, the unit must be serviced before it will work again.
3. Miscellaneous
If the unit will not be used for a long period of time, turn off the power, drain the unit of water, and close the
manual gas valve on the supply line.
