Never take apart a Bissell ProHeat that is plugged in or active, or else you risk severe injury.

The Bissell ProHeat cleaner serves as an upright vacuum as well as a carpet cleaner. Unlike traditional vacuums, the ProHeat can penetrate carpet fibers with water and steam, removing stains and odors left behind by pets, spills and other accidents. The water and soap flow into the carpet through the machine through a series of lines; if one or more of these lines becomes clogged, the unit stops working. Take the assembly apart and clean the lines, making sure they are not tangled, to return the ProHeat to its proper level of functioning.


Step 1

Make sure the Bissell ProHeat is turned off and unplugged; never attempt repair efforts if the machine is active or plugged in. Recline the handle backwards completely and set the SmartMix option to "normal" setting.

Step 2

Pull out the two tanks by their handles and set them aside. Remove the clear cap, red spinner and filter that connect to the tanks. Unscrew the two screws holding the nozzle window in place and lift it straight up to remove it.

Step 3

Unscrew the four screws placed at the top of the main housing unit; the screws are near the wheels. Pull the main housing from the larger unit; on some units you may have to unsnap a few catches at the front of the housing.


Step 4

Pull the ends of the lines from the unit and inspect them. Use a thin finishing nail or other small, thin tool to remove any clogs that you can see in the lines. Replace the lines when they are clear.

Step 5

Examine all lines for hints of pinching or kinking. Straighten any pinched or kinked lines with your fingers or with the help of your screwdriver. With the lines cleaned and straightened, there will be no more clogging in the system.

Step 6

Reassemble the unit to return it to regular use.
