The Bissell ProHeat deep cleans carpets and upholstery. It also washes hard flooring. The machine's "formula" tank is filled with detergent. One half of its "two-in-one" tank, known as the "bladder," is filled with warm water. The machine sprays a solution of water and detergent on to the surface being cleaned. Brushes agitate the cleaning solution, which is then sucked into the empty "recovery" section of the two-in-one tank, along with the loosened dirt. If your ProHeat fails to distribute cleaning solution, or suck it back up, there are a number of steps you can take to remedy the problem.
Ensure the two-in-one tank, which is contained within the floor cleaning head, is securely in position. Lift the tank away from its housing, using its carry handle. Place it back in its housing, making sure it is firmly seated.
Check that the hot water bladder, which is part of the two-in-one tank, contains hot water. Also ensure the formula tank, which is located on the rear of the machine at the bottom, contains the correct Bissell detergent for the surface you are cleaning. The system will not function if either of these tanks is empty.
Turn your Bissell ProHeat off, wait for one minute, and switch it on again. Press the trigger which releases the cleaning solution. This will solve the malfunction if it is caused by the machine's pump losing its prime.
Examine the "ready tools dial," which is located on top of the two-in-one tank, if the machine fails to suck up cleaning solution it has distributed. The dial should be set to either "floor cleaning" for carpets and hard floors, or "tools" when you are cleaning upholstery above the floor. If it is set wrongly, the vacuum function will fail.
Empty the two-in-one water tank. Once the maximum amount of cleaning solution and dirt is sucked up, the tank's red float door closes. This means the vacuum function will not operate until it is emptied. When you empty the tank, remember to refill the bladder with hot water.
Ensure the top half of the two-in-one tank, which you have to remove to fill with water, is correctly attached to the bottom portion of the tank. Check to be sure that the lip of the top tank is firmly in the groove that attaches it to the bottom tank.
Switch the Bissell ProHeat off if the suction fails after you bump into a piece of furniture, or if you have been moving the machine backwards and forwards rapidly. This type of jolt can cause the red float door to move into the closed position. Turning the machine off allows it to move back into the open position.
