Troubleshooting Central Command
Note: this machine is operated by a sophisticated electronic "controller" that has many fail-safes within it. It
self-analyzes problems and flashes a four-digit alpha-numeric code of what is wrong in the LCD window.
Most of these codes require a technician attention. You should not attempt repairs you are unfamiliar with, especially if
you are not authorized to work on this equipment.
The complete list of codes is published in the
simplified electronic troubleshooting manual, which is available to
authorized and certified distribution technicians. However, we have included the basic codes that you can usually
resolve yourself.
1. 7601 and 7602 Error.
Scrub deck current over load.
This can occur when driving over a bump in the floor. To
restart, turn off the key and turn it on again. To avoid this
error, either slow down on bumpy parts of the floor, or
reduce down pressure on the pads.
2. 1500 Error. There is an open in the parking brake
circuit. Check the parking brake wiring and the parking
brake coil to find the open circuit.
3. 7700, 7701, 7702, and 7703 Error. The vacuum motor
has exceeded their authorized power limits. Turn off key
and turn on again to clear.
4. BOOST ON Allows front wheel drive to draw more
power when needed to climb ramps for 30 seconds.
