Can you hear the pump running even though no water or solution is dispensed?
A pump sound without output suggests a blocked, air-bound, disconnected, or failed liquid path rather than a missing command alone.
If yes, possible repair paths include:

Why Is My Wet Cleaner Not Moving Water?
No liquid flow means the machine does not dispense, hydrate, collect, or recover water as designed; it is different from liquid escaping onto the floor or into the housing. Tank seating, valves, onboard tubing, pumps, wet rollers, recovery paths, sensors, and controls can each stop flow.
Important distinction
A symptom is not a repair diagnosis
The same symptom can come from several assemblies. The options below explain what our technician may inspect; final diagnosis, parts selection, and pricing happen through professional service.
Compare the clues
What else is happening?
You do not need to test or take apart the vacuum. If you have already noticed one of these combinations, it can help narrow which professional repair is most likely.
Is the pump silent even though the machine indicates that dispensing should be active?
A silent system can involve the pump itself or the controller and sensor logic responsible for commanding liquid movement.
If yes, possible repair paths include:
Does the machine dispense liquid but leave the floor wet or fail to recover dirty water?
Dispensing without recovery shifts attention toward the wet roller, scraper, pickup chamber, or recovery side of the liquid system.
If yes, possible repair paths include:

Repairs that can fit this symptom
These are professional service possibilities, not a definitive diagnosis. Our technician confirms the failed assembly before recommending or pricing a repair.
Pump or Liquid SystemPossible professional repairThis repair becomes more likely when:A confirmed onboard valve, tube, pump, spray channel, or recovery path does not move liquid.View professional serviceWet Roller RepairPossible professional repairThis repair becomes more likely when:A worn, dry, jammed, or incorrectly seated wet roller cannot distribute or collect liquid correctly.View professional serviceControl Board RepairPossible professional repairThis repair becomes more likely when:Tanks, paths, roller, and pump test correctly but a confirmed controller does not command liquid flow.View professional service
Service timing
Stop using it and schedule an inspection
Running a dry pump, saturated roller chamber, or failed recovery path can damage the liquid system and allow moisture into areas not designed to hold it. Stop when flow behavior changes instead of repeatedly cycling the function.
Useful service details
What to tell our technician
Share only what you have already observed. These details are specific to will not dispense or recover liquid and help us arrive prepared without asking you to open or test the machine.
- Whether clean water fails to dispense, dirty water fails to recover, or both functions stop
- Whether the tank empties, the roller becomes evenly wet, or liquid remains trapped in one path
- Any exact flow, tank, pump, roller, or recovery error shown by the machine
- Whether the problem began after storage, cleaning solution residue, scale, a jam, or tank removal
Repair intake
Still not sure which repair fits?
Start with the make, exact model, photos, and what the vacuum is doing. Inspection confirms the failed assembly before we source service parts or begin repair work.
