MAIN CONTROLLER ERROR CODES (CONTINUED)
Error Code Fault Description Troubleshooting Action
E08 Solution solenoid overload 1. Check for a wiring problem. 2. Check coil resistance (spec. is
185 Ohms + or – 15%). Replace solution solenoid if lower than 157
Ohms.
E17 Scrub deck lift actuator 1. Check for disconnected actuator wiring, open in
circuit open (**) wiring or defective actuator motor. Repair or replace. 2. Check controller
output voltage should be 36V if 0V controller failure (replace).
E18 Scrub deck lift actuator short 1. Check for binding or frozen brush lift linkage and excessive weight
on brush deck. 2. Check for short circuit* in brush lift motor and wiring.
Repair or replace.
E21 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 modi fi cations (this is a special cable and must be
replaced with the original OEM).
3. Check resistance on brush motor solenoid. Nominal resistance specs are:
• K1 - White-Rodgers brand = 120 Ohms
• K1 - Ametek
®
brand = 102 Ohms
If the resistance is less than 20% from spec, replace the solenoid.
4. Check if brushes are installed.
E22 Scrub motor short Same as E06.
E23 Vacuum motor circuit open (**) 1. Check for disconnected vacuum motor wiring, open in wiring and defective
vacuum motor. Repair or replace.
2. Check resistance on vac motor solenoid. Nominal resistance specs are:
• K2 - White-Rodgers brand = 120 Ohms
• K2 - Ametek
®
brand = 98.5 Ohms
If the resistance is less than 20% from spec, replace the solenoid.
3. Check controller output voltage should be 36V if 0V controller failure
(replace).
E24 Vacuum motor short Same as E07
E25 Solution solenoid circuit open (**) 1. Check for disconnected solenoid wiring plug, open in wiring or
defective solenoid. Repair or replace. 2. Check controller output voltage
should be 36V if 0V controller failure (replace).
E26 Coil / solution solenoid short 1. Check for a short circuit* in wiring or solenoid coil. Repair or replace.
E27 No accessory / wiring 1. Loss of battery (pos.) output to all system contactors (brush, solution
solenoid and vacuum) and system accessories (headlight, warning
beacon, solution pump). 2. Check controller accessory terminal output
(J2-8 Wht/Brn wire) voltage should be 36V if 0V controller failure
(replace).
*Short Circuit de fi nition:
• A short circuit is a parallel path of very low resistance, often caused accidentally.
• With low resistance there is an excessive amount of current.
• The excessive current will either melt the wires or open a fusible link.
