Bissell 7901-1 The soap doesn't mix with the water when I pull the trigger, I can see the soap isn't being used when I do the carpets. What can I do, have no problem taking this machine apart.

    My machine was not using detergent so I took it apart. The detergent appears to have blocked the smart mix valve. I cleaned this and the associated pipework out but have a problem with reassembly. I have read red devils solution of 16th February but although I am pretty competent am unable to understand his explanation!

    Further more detailed advice needed please. Pat

If the mix valve knob is turning smoothly, then most likely the cap and valve for the sop bottle is bad. Also make sure that the seal is on the cap at the bottom of the bottle and not sitting in the hole.

Bissell carpet cleaner not sucking up.


I have a Proheat 2X and had the same problem. I tried the Water Rinse setting and found water came out and was suctioned properly, but on the Light Clean, Normal Clean, and Heavy Traffic settings, the unit failed to do anything. Problem may be with leaving the soap dispenser in-place, which might scum up the tubing.

SO, an alternative to throwing out my unit and buying somethign else was to put one capful of the Bissell soap in the water resevoir and keep the unit on Water Rinse. IT WORKS BEAUTIFULLY NOW. Don't know if this will help, but at least I didn't have to buy a new unit. Rinse everything after using and there's been no problem.

A friend loaned me her Bissell Proheat Turbo carpet cleaner and I don't know how to use it - any help?


I like these cleaners.

First vacuum your carpet very thoroughly.

Depress the lever to tilt back the handle.
Grab the tank from the base. Remove the lid.
Fill the bladder with hot tap water. Replace the lid, and place tank back into the base. Put the handle back upright until it locks into place.
Take the soap container on the side and fill it with the Bissel soap solution. Place your dial on floor cleaner, and select either soap or heavy traffic.
Turn on the machine and the heater. Take your machine to the far end of the room and depress the handle put the machine in the corner depress the trigger and you will see a little spinning thing on the machine starting to spin - this means that the solution is blending and the spray is wetting the carpet. Pull the machine slowly back towards you about three feet and then let go of the trigger and pull the machine a couple more inches. When you stop the trigger will release. Push the machine forward and repeat the pull pass this time without depressing the trigger. For the next pass - overlap each and every pass (I do each pass at the half way point). Do this along the back wall. When you depress the trigger and that spinning dial does not spin - you are either out of water or out of soap. Go over the entire room with this technique.
Now this next step is VERY important. You have to do the whole room process AGAIN - this time with NO SOAP. I have used these machines for years and trust me - if you don't go over it again - your carpet will be a magnet for dirt. This time empty out your soap cup and rinse it out and refill it with WHITE VINEGAR. Again fill your tank with hot water. Re-do the entire room as if you are shampooing the carpet.

Let the carpet dry overnight - the next morning I would recommend applying scotchguard carpet protector (you can get the cans at H.D. or Lowes. Yes the Bissell solution has scotchguard, BUT when I apply the scotchguard again - the carpet stays so much cleaner so much longer.

Do it right the first time and don't cut corners and you will have the cleanest carpet on the block. It's a long process to do it right, but the end result is worth it.

OR if you want to save money and use something more environmentally friendly - fill with white vinegar. This will work just as good and leave your carpet less sticky from the soap and your carpet will stay cleaner longer.

Bissell Proheat Pro-Tech #7901 will not spray any liquid to the carpet and red cross indicator is not turning,but comes out of attactments


The 7920 is a 220 volt version of the 7901. I found a shop in New Zealand of all places that has service manuals on line. They are sort of picture books, but using them has saved me a lot of money as it makes repairing much easier. Here's the link you'll need. Good luck. If you need any more help, just add a comment to your post and it will go to my e-mail and let me know. The heads you clean are just the outlet spray heads when they get gunky.

How much soap and how much water do I put in the Bissell pro heat?


You are supposed to buy the Bissell soap. On the bottle depending which cleaner you need. The directions are on the bottle. Please do not use house hold cleaners because you can cause serious damage to the vacuum.
Go here, this pg. shows the 7901-1 click the user guide pdf & print the instruction if you choose:

Soap not dispensing


Hi. Try it just using cold water only. If this now flows ok the water you are putting in to tank is to hot causing pressure to build up in tank which which causes the plunger to not be able to push hard enough against valve in the tank.
