Indicates System Pass
Indicates Right Brush Motor Fault
Indicates Water Valve Fault
Indicates Wand Pump Fault
Indicates FaST Pump Fault
Indicates Left Brush Motor Fault
Indicates Scrub Head Actuator Fault
Indicates Controller Fault
Note: If Optional FaST and/or Wand Pump are installed, each switch must be in the ON position before entering Self-Test Mode. If FaST
or Wand Pump switches are in the OFF position when entering Self-Test Mode, that circuit will not be tested.
1. Hold the (-) Down pressure and (+) Increase Water buttons simultaneously on start-up. Machine will perform Self-Test for about 30-40
seconds.
2. After the self-test, either the One-Step Button LED will be lit solid to indicate system OK, or another panel LED will be flashing (which means
OPEN fault) or solid lit LED (which means a SHORT fault) to indicate a system failure.
In the example above, a blinking Low Down Pressure LED would indicate an open in the Scrub Head Actuator circuit. A solid Medium Solution
LED would indicate a short in the FaST Pump circuit.
