Tank filter and Float door: are they to snap into each other or is the door to flap freely

If your ProHeat 2X machine is not suctioning properly, first check the motor duct gasket. To check this, first remove the tank and place your hand over the rubber square opening. If there is no suction there, please take your machine to a BISSELL Authorized Service Center for inspection. If your machine does have suction at the duct, continue to check the following:
- Ensure the Ready Tools Dial is set to the appropriate setting (Floor Cleaning or Hose Attachments).
- Remove the tank from the machine and ensure the tank lid is attached properly. The front window must first hook onto the lip of the bottom of the tank and then drape over the tank. Latch the bottom tank to the top tank lid. THIS LID CANNOT BE ATTACHED PROPERLY IF THE TANK IS NOT REMOVED FROM THE MACHINE.
- Make sure the Water Tank is not full on the outside of the bladder. If it is, empty the tank.
- Ensure the hose is firmly attached to the back of the machine. If not, re-insert as necessary by twisting into place.
- The machine must be in an upright, locked position and set to the Hose Attachment setting. If the handle is slightly tilted back while using, it will create a small gap at the suction inlet (where handle meets gasket, above the Bottom Tank) which will cause little or no suction.
- Check the red Tank Lint Screen for debris. If the Lint Screen is dirty, the unit will have poor suction. Clean the Lint Screen if necessary.
- If the float flap door in the tank lid is activating prematurely when you turn the machine on, this flap door should be replaced.
- Check the Tank Lid and Tank for damage.

If you continue to experience low suction, please take your machine to a BISSELL Authorized Service Center. The warranty on your machine is one year. To locate your nearest BISSELL Authorized Service Center, click here.

First check the motor duct gasket. The motor duct gasket is visible once the tank is removed. It is located underneath the handle on the top of the base of the machine. It has a black rubber coating around it. If there is no suction there please let us know. If your machine does have suction at the duct, continue to check the following:

- Ensure the Ready Tools Dial is set to the appropriate setting (Floor Cleaning or Hose Attachments).
- Remove the tank from the machine and ensure the tank lid is attached properly. The front window must first hook onto the lip of the bottom of the tank and then drape over the tank.

Trythe following suggestions to see if you can get your machine suctioning properly:

1) Remove the Tank-in-Tank Assembly and place your hand over the motor intake valve. This valve is located next to the Floor Nozzle gasket (at the top of the Floor Nozzle window) and behind the SmartMix Bottle. If you feel vacuum-like suction at this area, your suction power of the unit is working but air is escaping at some point. If there is no suction at the motor intake valve your machine will need to be inspected by an Authorized Service Center Technician.
2) It is possible the Floor Nozzle on your machine is inserted incorrectly. This would directly affect the suction of your machine. Please follow the directions below for removing and replacing the nozzle.
Before starting, please be sure the machine is unplugged and the machine handle is reclined.
To remove the Floor Nozzle window, first detach the Phillips head screws located at the base of the nozzle. Then, remove the Tank-in-Tank Assembly. Next, pull forward at the top of the Floor Nozzle window to release the tabs of this window from the receiving holes of the machine. This window is designed to allow access for cleaning.
When replacing the Floor Nozzle window, please be sure the tabs at the TOP of the nozzle are properly inserted into the receiving holes provided. If you do not have the tabs in place properly, the suction power of the machine could be affected.
Rotate the window down into place and replace the screws.
3) Ensure that the Ready Tools knob (diverter knob) is in the proper setting and the valve opens and closes freely. Ensure the black foam gasket is in place under the valve.
4) Check to ensure the Tank-in-Tank assembly is seated properly and that it is not full of dirty water. (If this tank has a drain cap, make sure it is in place and that it has a black o-ring).
5) Check the float and baffle to ensure they are properly installed on the Tank-in-Tank. The larger square portion of this part should be below the clear baffle of the tank with the red flag portion of the float resting on top of the baffle.
6) Check the Tank-in-Tank and lid for damage. Is the lint screen clogged? Make sure the lint screen is in place on the tank lid and not placed into the motor duct. Also, clear the holes on the lint screen.
7) Check to see if the upholstery hose has suction. If the hose has suction and the floor nozzle does not, check the diverter valve to see if it opens and closes freely. This can be seen through the Floor Nozzle window as you switch the diverter knob from the floor to tools setting.

Check your filter screen insde the upper tank. if your model has a wrap around filter try to pull it down about 1/2" to maximize air flow.

Possible Causes Remedies 1. ReadyTools dial may be at wrong setting. 1. Set ReadyTools dial to either FLOOR CLEANING or TOOLS setting. 2. Tank may not be seated properly. 2. Pick up both the 2-in-1 water tank and formula tank and reseat them so they fit snugly on the unit. 3. Tank may not be assembled properly. 3. Check to make sure the "lip" of the nozzle is securely hooked into the groove on bottom of Tank (see page 9). 4. Solution or 2-in-1 water tank is empty. 4. Check fluid levels in heavy duty bladder and formula tank. 5. 2-in-1 water tank has picked up 5. Empty 2-in-1 water tank. Refill maximum dirty water and red float heavy duty bladder with clean door has closed. hot tap water and replace. 6. Red float "door" in the tank may have closed 6. Turn the machine OFF ( O ), as a result of bumping an object or moving allowing red float door to release into machine back and forth too quickly. the open position. Turn unit back ON ( I ) to continue cleaning. Be sure your forward and backward strokes are done at a slower pace.

There is a float in the water collection chamber that closes off the opening below the filter. Make sure that the float is moving freely and the hole under the filter is not obstructed. Reply if this is not the problem, I have one sitting here that I can look at for other possibilities.
