Floor scrubber fault finder
Diagnose a floor scrubber problem one step at a time, starting with the quickest and most likely fixes, and see when to call a technician.
How the fault finder is ordered
Each symptom lists checks in the order an experienced technician would work through them: the quickest, cheapest and most common causes first, then the parts that are slower to reach or more expensive. Most scrubber problems are found in the first three steps, usually in a hose, a blade, a filter, a switch or the charge state.
If the machine shows an error code, look it up in the operator manual first, then use the matching fault family guide. For more depth on any symptom, open the full troubleshooting guides.
Frequently asked questions
What is the most common floor scrubber problem?
Poor water pickup, which shows up as streaks or water left behind. It is usually caused by a worn or misadjusted squeegee, a clogged hose, or a recovery tank lid that is not sealing.
Why does my scrubber turn on but not scrub?
Check that the scrub head is lowered and the brushes are fitted, then look for a tripped brush motor breaker, low battery cutout or an overcurrent fault from too much down pressure.
Can I fix a floor scrubber myself?
Most first-line fixes need no special tools: cleaning filters and hoses, flipping or replacing squeegee blades, checking breakers and charging correctly. Motor, controller and wiring faults are usually technician work.
What information should I give a technician?
Give the make, model and serial number, the hour meter reading, any error code exactly as displayed, when the fault happens, and what you have already checked.
