TROUBLESHOOTING GUIDE
This guide provides specific instructions to aid in troubleshooting and repairing most of the
possible problems encountered during the use of the PRO 1900 carpet cleaning system. This
guide has been provided to help reduce your down time and the cost that would be involved in
contacting your local distributor or the national service center to diagnose each minor
problem.
MACHINE WILL NOT START WHEN KEY IS TURNED
Does not crank over:
1. Depress circuit breaker on face panel.
2. Check battery charge and connection terminals.
3. Check for disconnected or broken wiring.
4. Check continuity on ignition switch.
5. Check starter solenoid.
6. Check starter.
7. With the key removed from the machine ignition and the pump switch “OFF”
remove the machine cover. Loosen the belt from the engine to the blower. As-
sure that they are not seized. The blower should rotate freely. The pump will
need to be rotated with a wrench.
If engine cranks over but will not fire:
1. If “SYSTEM TEMP” light is illuminated, input water may be over 140 degrees
or output water may exceed 280 degrees. If this occurs add fresh cool water to
the water tank.
2. If “ENGINE TEMP” light is on the engine has overheated.
3. Check fuel level.
4. Check recovery tank – if it is full the machine will not start.
5. Check for defective recovery tank shut-off switch as follows.
a. Bypass the wiring to the float tank shut-off switch by disconnecting one
wire. If the machine starts this means the float switch in the
recovery tank is non-operational and mechanism should be cleaned
or replaced.
