Troubleshooting Action
Err07
Scrub motor overload
Check for binding in rotation of brushes or improper brush lift actuator
operation. 2. Check the negative supply cable at the brush motor for
a wiring problem or improper modifications (this is a special cable and
must be replaced with the original OEM PN 56410113). 3. Check to
see that the proper brush type is selected

(disc or cyl).
Err08
Scrub motor severe overload
1. Same as Err07. 2. Check for short circuit in brush motor or wiring.
3. Inspect gearbox for failure. Repair or replace.
Err09
Scrub motor circuit open (**)
1. Check for open in brush motor wiring or defective motor. 2. Check
the negative supply cable at the brush motor for a wiring problem or
improper modifications (this is a special cable and must be replaced
with the original OEM PN 56410113). 3. Replace defective brush
motor contactor. 4. Check if brushes are installed.
