Floor Scrubber Error Codes: A Fault Database Organized by Fault Family

A floor scrubber error code is the controller telling you which circuit it is unhappy with, but the code itself is not universal. The same number can mean a brush overload on one machine and a throttle fault on another, and the meaning can even change between firmware versions of the same model. That is why this database is organized by fault family rather than by code number. Every scrubber controller watches the same handful of things: battery voltage, motor current, open and shorted circuits, switch positions, and communication between its own modules. Once you know which family a code belongs to, the diagnosis is largely the same regardless of brand.

Start with how to read scrubber error codes, which explains display types, service modes, fault logs and how to find the code table in your manual. Then go to the family that matches your message: battery and low voltage faults, brush motor overcurrent faults, vacuum motor faults, drive and throttle faults, solution and pump faults, charger fault codes, controller and communication faults, and sensor and switch faults. Each page covers what the controller is detecting, common triggers ranked by likelihood, multimeter checks, fixes, reset behavior and a fault record worksheet for your technician. If there is no code at all, use the symptom-based fault finder instead. Always confirm the exact code meaning in your own machine's manual before replacing parts.
