NOTE:
THIS MACHINE IS OPERATED BY A SOPHISTICATED ELECTRONIC "BRAIN" THAT HAS MANY FAIL-SAFES WITHIN IT. THE
BRAIN SELF-ANALYZES PROBLEMS AND FLASHES A FOUR-DIGIT NUMERIC CODE OF WHAT IS WRONG IN THE
LCD
WINDOW.
MOST OF THESE CODES REQUIRE A TECHNICIAN'S 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 TROBLESHOOTING MANUAL,
WHICH IS
AVAILABLE TO TECHNICAL PEOPLE. HOWEVER, WE HAVE INCLUDED THE BASIC CODES THAT YOU CAN USUALLY RESOLVE
YOURSELF.
1. 1E03 AND 1E04 ERROR.
CHECK THE SMALL SAFETY
SWITCH NEXT TO THE RED PLUG BELOW THE DASHBOARD.
THIS SWITCH WILL TURN OFF THE TRACTION DRIVE AND
BRUSHES AS A SAFETY FEATURE WHILE THE CHARGER IS
PLUGGED IN. THE SWITCH MAY BE STUCK, OR THE PLUG
TWISTED AT AN ANGLE, ENGAGING THE SWITCH. THIS
CODE WILL ALSO FLASH IF THE WIRING BECOMES VERY
WET. IN THIS CASE, EITHER WAIT UNTIL THE WIRING DRIES
OUT, OR CALL A TECHNICIAN.
2. 7601 AND 7602 ERROR.
SCRUBDECK CURRENT OVER
LOAD. THIS CAN 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
DOWNPRESSURE ON THE PADS.
3. 1600 ERROR.
VOLTAGE EXCEEDS THE MAXIMUM.
EITHER THE BATTERIES ARE MIS-WIRED, OR THE CHARGER IS
STILL PLUGGED INTO THE MACHINE.
4. 7700, 7701, 7702, AND 7703 ERROR.
THE VACUUM
MOTOR HAS EXCEEDED THEIR AUTHORIZED POWER LIMITS.
TURN OFF KEY AND TURN ON AGAIN TO CLEAR.
