Fault Finding

This machine can be used for dry pick up, wet pick up, and carpet/upholstery cleaning.

Dry Mode

If the vacuum cleaner stops working: Switch off and remove the plug before investigating.

If the vacuum cleaner will not pick up debris: Switch off, remove the plug, inspect the floor tool, wands, and hose for blockages. If no blockages are found, the dust bag may be full, or the filter may be blocked.

Wet Mode / Spray Extraction

If the vacuum cleaner stops working: Switch off and remove the plug before investigating.

If the vacuum cleaner has a blockage and will not pick up liquid: Switch off, remove the plug. Check if the float valve has operated (this shuts off suction and changes the motor pitch). Remove the power head and empty the container. Check floor tool, wands, and hose for blockages.

If the spray nozzle is blocked: Use a pin to clear the blockage.

If there is no spray from the nozzle and the pump tone changes: The solution tank is empty; refill it.

Flush the system with clean water after use.

Always inspect the machine for damage after use.
