It should prime itself. But when you put the top cover back on, were the water lines routed so as not to pinch? Also, the piston needs to be on the bottom of the smart mix knob, and in the water only selection when the cover is pushed into place. Make sure that the gasket at the bottom of the water tank is on the valve. Sometimes the heater gets clogged where the water lines hook up to it.

No water getting to brushs


Hi! Sometimes it is necessary to prime the trigger under the handle to get the solution flowing. To prime the trigger, recline the handle and pump trigger about 60 times. Then, power the cleaner on and squeeze the trigger for about 60 seconds. The solution should start to dispense. If it is still not dispensing there may be an issue with the pump assembly on the cleaner. We would recommend taking the cleaner in to a Hoover authorized service center for repair. Follow the link to locate one nearest you. Service Center Locator

Hope this helps!

It turns on, it makes the noises, the brushes are spinning, but the water/cleaner isn't getting to the floor


Hello! Sometimes it is necessary to prime the trigger to get the solution flowing. To prime the trigger, recline the handle and pump the trigger vigorously 60 times. Then, power the unit on and squeeze the trigger for about 60 seconds. The solution should begin to flow. It may be necessary to repeat these steps a few times. To avoid internal damage be sure you are only using the cleaning solution recommended for this unit. If the unit is still not dispensing we recommend taking the cleaner in to a vacuum repair center for repair. Follow the link to locate the nearest authorized service center to you.

Have a hoover steam vac that wont **** up the water brushes spin


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.
or

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.

New replacement pump on Bissell ProHeat Protech not working


Not sure if I have the same model but this is what I found on mine this morning - wire to switch in the handle came off. Un-plug power cord. Unscrew top two screws on upright handle and remove the front cover above the trigger. see if wires are connected. top connector is not used - if you do solution will spray all the time. Good luck!

Flow indicator not spining


Yes I also had this problem after just one use. There's several things that you should check. 1. pull side panel off where the belt is located and see if the liquid in the clear tubbing is flowing.I there is a bubble in the line the pump has lost it's prime and needs to be turned off for a minute then restarted. 2. make sure the belt is not broken this drives the solution pump and well as the cleaning wheel. 3. the lines that the solution flow though are clogged. always rinse the machine with water when done cleaning. Good luck.

Not putting out water


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:

9c4a1a7.jpg

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.

1e843f8.jpg

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:

026cf8d.jpg

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.

If you found this helpful, please kindly rate my repair helpful so that other Fixya users with the same problem can easily find this solution. By rating the repair you are also encouraging repair professionals to continue posting free repairs. Thanks in advance,

Bissel proheat won't spray from bottom or attachment


I had the same problem. After 3 weeks of seals belts pump etc. I was ready to give up.
The problem with mine as I suspect with others is the seal on the water tank.
The bottom plastic connector is not high enough to allow the water to flow to the pump.
My solution was to raise the bottom connector 3/16 of an inch.
I did this with a piece of plastic cut like a flat washer or auto gasket material could be used.
The connector must be removed from the bottom by pressing on the tabs. Hope this helps.

Pump prime lost


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
