Hako Scrubmaster B12: Manual Matching & Water Pickup

Start with the model number 7745.05. This reference covers the linked B12 manual, not every B12 or B12 Evo edition. It helps an operator locate the relevant instructions and prepare an accurate service report.

Which B12 manual is linked here?

The English instruction manual hosted by Hako Norway identifies Scrubmaster B12 (7745.05) on its cover. The technical table on EN-10 lists a 24V supply and a 385 mm washing width. Controls are on EN-16, pre-use checks on EN-19 and troubleshooting on EN-30.

Read the complete machine identification plate before choosing a document. Save the model, serial number and PDF filename together. If the controls or fitted equipment do not match the illustrations, ask the local Hako service partner to confirm the correct edition. A shared B12 name does not establish that electrical components, charging instructions or spare parts are interchangeable.

The machine scrubs but leaves water behind

The EN-30 troubleshooting table associates poor drying with suction activation, an obstructed suction tube, squeegee setup, a full recovery tank or worn blades. Its vacuum-motor section also distinguishes activation from an electrical fault.

First describe the result: a narrow streak, water at one edge, or a broad wet path. Note whether it happens on straight passes, turns, or only after some cleaning time. Record whether suction is audible. These observations help distinguish a floor-contact issue from a loss of recovery performance without claiming a diagnosis.

Stop the machine and follow its isolation instructions before inspecting permitted operator-accessible components.
Use the applicable manual to check tank condition and accessible pickup components. Record what was found and what changed.
If the symptom persists, provide the observations to service. Avoid ordering a motor simply because water remains on the floor.

Little or no solution reaches the floor

The same manual separates no-water causes: an empty solution tank, water enable control, closed tap, blocked filter or solenoid fault. It treats unsuitable or worn cleaning accessories separately from these flow problems.

In the report, write “solution does not reach the brush area” if that is what you observe. “Not picking up water” describes a different part of the cleaning cycle. Include the selected settings and the point at which the issue started. Electrical and solenoid testing belongs with qualified service; the operator record should preserve evidence rather than propose internal repairs.

Symptom: pickup / flow / brush / starting ___
Time until symptom: ___
Indicator and sound: ___
Tank condition observed: ___
Permitted check and result: ___
