Why doesn't water comes out ?

Check the Shampooer Tank seating. Turn the unit off and unplug. Remove the Shampooer Tank and inspect the reservoir for any foreign substance. Reseat tank. Replug and turn on unit. Remember to keep your filters clean. There's the lint filter on the cap of the main tank and there's the Flow Filter (Turn Flow Indicator Cap counter-clockwise to remove, remove rotor, and filter is under it. Clean and replace in reverse.) Bissell Consumer Care 1-800-237-7691 if you need. Additionally check you Use Guide for more information.

its likely that its just blocked up and need to be flushed out with clean water,,,sope forms a slimy mass if left in the shampooer for a long time

look on the vacuum where the suction is to pick up and you will see its clogged ,clean out the suction ports

Bad Pump. You pump is where the belt attaches to spin the brushes and also puts water on the floor. Take it to you local Best Buy to be serviced or a local appliance shop which may service it.

The Kirby shampooer deposits the foam onto carpet,and works it into the carpet with the shampooer brushroll.After the carpet is dry,use the vacuum itself to pick up the dry foam and dirt.The Kirby Shampooer is not an extraction shampooer

You have the vacuum and the basin, you put them together just like when you vacuum but don't put water in the basin. There is a large white container that comes with the shampooer. you fill that up with water and then you place the vacuum cleaner and the basin on top of that. Now you will need the water hose (not the one that has the gas pump hadle). Hook that in the same spot that you do for vacuuming. Then you take the shampooing handle( it will have a trigger and a little white bottle and some tubes hooked to it) the one end of it hooks to the water hose and the other end hooks to the wands. There are 2 wands that come with your shampooer. At the end of those the shampooer head will be attached. There are two separate tubes there is a thick tube ( there two tubes fused together) and a thin tube, they hook to the large white container that you fill with water. Just look and you will see where they go. Then there is a tube that hooks to the shampooer head at the bottom. The you take the little bottle and fill it with your shampoo. You should have gotten some clips to hool onto your hose so that you can keep the tubes attached to it so they aren't in the way. You should be set. I hope I helped.

Your shampooer is not broken. (sorry Fanny)

You are missing a wee screen that fits on the hole where the little hose plugs into the tank. Check inside the hose end or down inside your shampooer box. Here's a link to my online Kirby shampooer instructions...
