TROUBLESHOOTING CENTRAL COMMAND II
NOTE:
This machine is operated by a sophisticated electronic "CONTROLLER" that has many fail-safes within it.
The controller self-analyzes problems and flashes a four-digit numeric code of what is wrong in the LCD window.
Most of these codes require a technician's attention. You should not attempt repairs you are uncomfortable
with, especially if you are not used to working on electronics.
The complete list of codes is published in the simplified electronic troubleshooting manual, which is available to
technical people. However, we have included the basic codes that you can usually resolve yourself.
1. 1E03 AND 1E04 ERROR.
Check the small safety switch
next to the red plug below the dashboard. This switch
will turn off the traction drive and brushes as a safety
feature while the charger is plugged in. The switch
may be stuck, or the plug twisted at an angle,
engaging the switch. This code will also flash if the
wiring becomes very wet. In this case, either wait until
the wiring dries out, or call a technician.
2. 7601 AND 7602 ERROR.
Pads or brushes current over
load. This can can occur when the pads/brushes hit a
bump in the floor. To restart the pads, turn off the key
and turn it on again. To avoid this error, either slow
down on bumpy parts of the floor, or reduce
downpressure on the pads or brushes.
3. 1600 ERROR.
Voltage exceeds the maximum.
Either the batteries are mis-wired, or the charger is still
plugged into the machine.
4. 7700, 7701, 7702, AND 7703 ERROR.
The vacuum
motor has exceeded it's authorized power limit. Turn
off main power switch and turn on again to clear.
