Why won't the water come out?

The water pump is most likely burned out and needs to be replaced. Carpet machines are notorious for broken water pumps.

Hi there! To prepare for cleaning, put the solution and water in the top tank. While cleaning, all the dirty water gets sucked into the bottom tank. To clean squeeze trigger to release cleaning solution and slowly push carpet cleaner forward, this equals one wet stroke. Continue to squeeze trigger and slowly pull carpet cleaner back toward you (second wet stroke). Release trigger and slowly push carpet cleaner forward over area just sprayed with solution (dry stroke). Then slowly pull carpet cleaner back toward you without squeezing trigger (dry stroke). To avoid saturating the carpet don't do more than 4 wet strokes over one area. Always end with dry strokes. Here is a link to view the instruction manual if needed.

Hope this was helpful!

this could be the problem

1) Make sure there is water in the solution tank.

2) Try priming the machine by instructing the consumer to squeeze the trigger

repeatedly for 1 to 2 full minutes. Important: If you cannot

squeeze the trigger all the way in, remove the tank from the back of the

machine and then try squeezing the trigger with the tank removed. There is an

internal valve that could be sticking. By removing the solution tank and squeezing

the trigger, it should break it loose, allowing the trigger to be fully depressed.

3) Make sure the open end of the siphon tube in the solution tank is not pushed into the

side of the tank, covering the end of tube. If it is, push the bend in the

Siphon tube toward the back of the solution tank.

4) Check to see if the siphon tube has become disconnected from the outlet fitting on

the inside of the solution tank. If so, you need to buy a replacement solution tank. Parts

can be found at www.bissell.com

5) Check to see if air comes through the spray tip by repeatedly squeezing the trigger

with solution tank off the unit. If not, spray tip may be clogged. Try and unclog

spray tip with a pin or paper clip.

If still no spray, please check the following:

a) Make sure the solution tank is installed properly.

b) Check to see if black O-ring is present on rear connector to solution tank.

Look at the bottom, where the water comes out and comes back in? Is it filled with hair/dirt? It might need to be cleaned out where the water sucks up in at. Otherwise I would go to Hoover.com website for f.a.q.s or technical support.

If you find that your cleaning solution will not dispense, check that the tank is securely in the locked position. There is also a chance that the solution tank is empty, in which case fill it with cleaning fluid. Ensure that the recovery tank lid is firmly in place.

Prime the pump. Priming means to remove air from the system so that the cleaning fluid can flow to the tool. You "prime the pump" by attaching the tool to the hose and turning the carpet clearer to ON. Then put the tool on a hard surface or against your hand to block the suction. It may take up to 15 seconds to remove all the air. Once this is done, squeeze the trigger on the machine and begin to clean.
Thank You.

Try squeezing the trigger a few times repeatdly. This usually works for me.

Remove the clean water tank and look in the opening just behind the black grommet. Operate the trigger - you should see the valve move downward as the trigger is pressed. If it is NOT moving, then you will need to have the trigger plunger shaft repaired/replaced

Problem: Low suction
Problem: Clean solution won’t
dispense
Problem: Brushes/brush indicator
won’t rotate during floor cleaning
Possible cause
Possible solution

• No voltage In wall plug
• Check fuse or breaker
• Blown fuse/tripped breaker
• Replace fuse/reset breaker
Possible cause
Possible solution
• Recovery tank full/automatic
shut off engaged
• Remove and empty recovery tank
• Blockage In tool on end of hose
• Remove tool and clear blockage
• Recovery tank lid not on
correctly
• Make sure lid is on securely
• Recovery tank front panel not
replaced after stair or upholstery
cleaning
• Replace recovery tank front panel

Before using tool
It may be necessary to remove air from
the system (“prime the pump”) so the
clean solution will flow to the tool. Follow
these steps:
1. Attach tool to hose and turn the carpet
cleaner ON.
2. Put the tool on a hard surface or
against your hand to block off the suction.
3. Wait a few seconds (can take up to
15 seconds). Then squeeze the trigger
and begin cleaning.

GOODLUCK!!!!

It may be necessary to remove air from
the system (“prime the pump”) so the
clean solution will flow to the tool properly. Follow
these steps:
1. Attach tool to hose and turn the deep
cleaner ON.
2. Put the tool on a hard surface or
against your hand to block off the suction.
3. Wait a few seconds (can take up to
15 seconds). Then squeeze the trigger
and begin cleaning.

For the attachments, turn the knob on the left to tool setting, that will open the valve at the top to allow suction thru the hose, then squeeze the trigger to spray. Close it when you are done or you won't have suction down below.

If the water is running out, either the valve at the bottom of the tank isn't working right or youy have a water line off, probably have to take off the top cover to check that out.
