If the recovery tank is not seated properly on the Hoover cleaner, the tank will not work correctly. Turn the latches on each side of the tank away from the base of the unit, and lift the tank off of the base. Reseat the tank firmly on the vacuum cleaner base so the tank clicks into place, and close the latches on each side. Wiggle the tank with your hand to verify the tank is firmly in position.
When the recovery tank has been operating well during cleaning and suddenly stops working, the tank is probably full. Open the latches, remove the recovery tank and empty the tank into a sink or drain. Rinse the tank with water, close the lid and replace the tank on the machine. Close the latches on each side and continue cleaning.
During cleaning, the nozzle may become clogged with debris, which will prevent additional water and debris from being pulled into the recovery tank. This may be interpreted as failure of the recovery tank. Pour 1 cup of water onto a hard floor and use the carpet cleaner to suction up the water. Repeat as needed until the debris is cleared from the nozzle. If the nozzle remains clogged, disconnect the power, manually clean out the nozzle and reconnect power.
When cleaning upholstery or using other Hoover attachments, the back panel of the recovery tank is removed, and the tool converter is slid into place instead. If the recovery tank fails to operate after the upholstery tool has been in use, make sure the tool converter is removed and the back panel of the recovery tank has been replaced and is firmly in position.
