Water Tank No water is coming out of water tank. Machine will heat and put down solution, but does not add water. We have checked seals, rings, water/solution levels, cleaned all filters, hoses, and checked the belt. Help!

THERE ARE O-RINGS THAT SEAL THIS , I THINK THERE RED/ORANGE IN COLOR FROM FACTORY IF I CAN REMEMEBER , REPLACEMENTS ARE AVAIL FROM HOOVER PARTS (OR SEARS) OR IF NOT BROKEN OR MISSING BUT ONLY NOT SEALING WELL , TRY A TOUCH OF PETROULEM JELLY ON THEM IT HELPS TO SWELL THEM UP TO SEAL BETTER

This sounds like a bad O ring on the metering plate, the plate that the solution tank rests on. Not the easiest fix but can be done in the right environment. I can give you some part numbers to start but you're better off having a shop that is familiar with these do the work.

Names and part numbers to get you started in finding a shop.
O ring #25156522
Metering Plate #38764031
and worst case scenario a cracked supply tank support assembly #41423018.
Explaining the problem to the service personnel and mentioning these parts will put them in the right place to fix your problem.

The most common reason for lack of pick up is that the lid is not fully seated on the dirty water tank. Be sure to hook the two tabs on the front of the lid, and then snap the rear latch into place. Another reason is that the duct on the front of the dirty water tank is missing. The duct may have been removed to install the hose, and was not put back in place. It is a square plastic piece, about the size of a slice of sandwich bread, which slides into the front of the tank. A far less common reason for no pick-up is that the seal that the tank sits on has fallen off the motor cover suction tube. You will see a round tube on the bottom of the dirty water tank. This sits on top of a large rubber seal on the motor cover when the tank is in place. Be sure the seal has not fallen down into the hood.

Try the following suggestions for the leaking issue:

- Check to see if the black or white "duck bill" gasket is misassembled or missing from the collection tank; ensure the gasket will open where the flat flaps meet and then reinstall it. The duck bill should be inserted into the curved side of the collection tank.
- Check to see if the solution tank/cap insert is leaking.
Note: When the solution tank is filled and turned right side up, the straw on the insert may fill with water/solution causing the tank to leak for a couple of seconds. This leaking should subside after the straw empties out.
- Check for proper placement of the o-ring on the cap insert. The o-ring should be between the bottle and the insert piece (part with the "straw").
Try the following for the suction issue.
- Remove the Collection tank and locate the circular motor duct on the base of the machine. Turn the machine on and feel for suction at this location. If you feel suction proceed as follows:
- Remove the gasket from the bottom of the Collection Tank. Ensure that this gasket is open (not sealed shut) at the top of the gasket where the flaps meet. If the end is not open, simply squeeze the end to open it. The “duck bill” shaped portion of this gasket should align with the rounded side of the Collection Tank.
- Check to make sure there are no cracks in the flexible vacuum hose or in the tool you are using.
- Make sure the collection tank latch is locked down securely.
- Check for suction at the end of the hose with the attachment off by suctioning water out of the sink or a cup. If there is low/poor suction, check the hose for clogs by raising the hose handle above the unit to allow the water to go into the collection tank.
The issues may be related as you can see some of the suggestions are similar.

Check to ensure there is liquid in the water tank and the formula bottle.

Note: This machine will spray with liquid in the Water tank only if the machine is set to the Water Rinse setting. On any other setting, you need to have liquid in the formula tank as well.

If no: add liquid to the Water tank and the Formula tank.
If yes: check each of the following....

- Check the bottom of the Water Tank and the Formula Tank to make sure each has a red auto-load gasket attached. Make sure the Water Tank and the Formula Tank are seated properly.
- Ensure the tank lid is properly attached to the bottom of the tank. To attach this properly, remove the Water Tank from the machine. Hook the front window onto the lip of the bottom container and then allow the window with lid to cover the complete tank. Secure the latch on the back of the bottom tank to the back of the tank lid. THE TANK LID CANNOT BE ATTACHED PROPERLY IF THE BOTTOM TANK IS ALREADY INSTALLED IN THE MACHINE.
-If everything is seated and attached properly, prime the machine by turning off the power, waiting one minute, and then turning the power back on and depressing the trigger on the handle.
- If priming the unit fails to fix the problem, remove the handle completely and re-attach. Once the handle is re-attached, re-attempt to spray.
If the machine continues to not spray, check the following:

REMOVE THE COLLECTION TANK:
• Make sure the unit is set to water rinse
• Remove the smart mix bottle and fill it with water only
• Place the smart mix bottle into the collection tank reservoir
• Run the unit and try to spray. If the machine sprays, you will be able to see the water level decreasing in the smart mix bottle and you will need to replace the bottom tank. It is possibly warped.

Hello,

Here's some trouble shooting tips that will help you figure out what's wrong with your Bissell Little Green Machine, and why the water won't spray out. You didn't mention how old the machine was, but if the machine is brand new, and you've never used this before, then you'll need to prime the machine for the first time.

To prime the Little Green Machine, remove the hose after filling the clean water tank, and press and hold the trigger on the hose for approximately 45 seconds. This will prime the pump, and get the water flowing.

If the machine is older, and you've already been using it, here's some other troubleshooting tips that you can do to try and fix the machine:



Step 1. Fill the clean water solution tank with water, and remove it from the machine. With the tank removed, press the piston at the end of the tank that fits into the machine. The piston is the spring loaded part in the top of the water tank that is pressed upwards when the trigger is squeezed, which in turn releases water into the machine. Press the piston inwards with your finger and see if water comes out.



Step 2. If water is released from the tank when you push the piston inwards, then your piston and cap assembly are fine. Next unscrew the cap to the clean water tank and make sure that the o-ring is present. This is the rubber ring that rests in between the cap and the tank.



Step 3. If your o-ring is not there, you'll need to purchase a new a new o-ring and replace it. If the o-ring is present, screw the cap back onto the tank. Inspect the receiver to make sure there is no debris blocking it. The receiver is the part on the machine that the tank sits on top of. If you see debris here, remove any debris that could be obstructing the tanks piston.



Step 4. After checking these three things, refill the tank with water, reinsert back into the machine and test to see if the water now comes out. If the water does not come out, move on to step 5.

Step 5. Unscrew the two screws on the handle of the hose, and remove the cover that the two screws secure.



Step 6. After removing the hose cover, inspect the hose that connects to the trigger assembly for blockages:



Step 7. If blockages are found, remove the tube from the trigger, and blow through the hose to remove any blockages, and reinstall the tube back onto the trigger.

Step 8. Reinstall the trigger assembly so that the metal spring's curved side is facing down so that it touches the trigger valve:



Step 8. After reassembling the hose, turn the machine on again and try spraying the hose again.

If none of these solutions fixed your machine, this most likely indicates that you need to replace your pump. The pump is the internal part that takes the water from the tank, through the hose, and finally sprays it out. The pump replacement is a moderately difficult repair, but if you'd like me to walk you through it, I'd be more then happy to do so.

Please feel free to ask any follow up questions, or let me know if you'd like for me to show you how to replace the pump. I'm always more then happy to answer any question that you may have.

Does water squirt out of the hose nozzle, if it does, then check the heater inside the handle asm. Make sure that where the tubes hook up to it are not clogged. If water doesn't squirt, check for the seal at the bottom of the tank, it needs to be on the tank, not in the hole, this is for the soap bottle, there is a seal on the bottom of it as well. The flow indictor cap is leaking air or maybe is too tight. If you had the top cover off, make sure that the tubes are routed right so as not to get pinched when the cover is put back on, the smart mix knob should be in the water setting and that the piston is on the bottom of the smart mix knob. Pump is bad. Try running a mix of vinegar and water to see if that unclogs the lines. Is the top cover and the base tight together in the back, sometimes the top breaks loose and it will raise up and it can't spray, just re-fasten it down.

On the bottom of the tank is a valve, push it in and see if water comes out Where the tank sits, there is a black round seal, is it in the proper place? The rod in the handle hits just under that seal, with the tank off, you can see if the rod is movin up and down when you depress the trigger. The resevior asm. may be bad, that is what the tank sits on.

When you place the clean water tank on the machine, there is a connection between the tank valve and the seal on the body of the unit. If you have been using the wrong solution, ie. lysol or pine sol, they contain elements that will cause the seals to absorb the solution and they will swell and the valve will not open to release the solution into the machine. If this is the case, you will have to replace the main seal on the machine and the small seal on the valve in the tank. I have seen this problem alot because it can be hard to find the proper solution that was designed for the machine.
Put cold water only in the tank and place it on the machine. As you are pushing it into place, look through the clear plastic of the tank and observe the valve. You should see it lift slightly and hear the "glug" of water flowing. You should also see bubbles rise up inside the tank. If this doesn' happen, then the seal and valve are probably compromised and will have to be replaced. Don't use any solutions or additives that contain petroleum distolates or solvent bases as these are the main culprits that will be absorbed and distort the seals.

After further examination of the pump I re-installed it in the machine and removed the inlet hose from the mixer valve body and placed the end in a shallow pan of water. I turned the machine on and the pimp picked up the water from the pan and pumped without failure for several minutes as I had the pump output refilling the same pan.
If I take the end of the inlet hose out of the pan for only a couple of seconds, the pump loses prime and will not recover until I remove the vacuum hose from the pump. Upon replacing the vacuum hose the pump primes and begins working.
At that point I suspected an air leak at the base of the water tank or somewhere in the mixer valve assembly. I then took the hose off of the tank fitting in the base and placed the end of the hose in the pan of water. Again, the pump performed without any problem. Therefore, I assume I have an air leak at the base of the tank where the tank connects to the machine.
I will explore this further and provide you with additional info as I make progress
