Water & soap spray constantly even when trigger is not depressed.
My carpet steam vav sprays water constantly even when the trigger is not depressed. I have checked all the switchs and the solenoids. The wiring seems to be right. Any ideas? Where can I find Service Instructions for this vac?
Re: Water & soap spray constantly even when trigger is...
This may be related. Mined wouldn't spray after it sat for awhile. I tore it down, tapped on the solenoids and reassembled. That worked.
Its possible the solenoids may be stuck in the open position although not as probable as stuck in the closed position.
Try checking for current at the solenoid without the spray handle being depressed. If you've got current then it might be up in the switch at the handle. No current makes it sound like a solenoid problem

The connection for the hose to the cleaner is also a valve assembly. There is a white plastic spring- loaded sleeve that the hose must push in for water to flow into the hose. Part # is 43523004. This is a rather flimsy part, mine cracked and cleaner continously leaks out the backside of the valve housing until the tank is empty GRRRRRRR!
www3.sears.com there are diagrams and parts lists for similar model F7452-900.

assuming the water will flow with the tool attachement but not to the carpet.
Remove the water tank. You will see 2 red tabbed plastic spray tubes.(where the spray comes out if not clogged) Pinch the clips to remove from the machine. Then you will need to pinch the hose clips to remove the red tabs from the hose. Clean out those red spray nozzles. Next step: have a towel ready and fill the solution tank with water. Put the solution (not water) tank on to where the water tank would go. Place the machine selection knob to rinse/wet only. Now with towel under the hoses that you removed the red tabs. Turn on the machine and pull the trigger to activate the water. You should see water flow out of the hoses that had the red tabs on them. If not, release and pull again the trigger several times. If only 1 hose has water coming out of it then block the one that works and try the process above again to de clog the one that isn't working. Good luck.
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.
This is a solution for the Bissell Pro Heat, although it may apply to other Bissell steam cleaners as well. This is for the problem of the cleaning solution continually spraying without stop.
I found a quick and simple solution to this problem.
This problem occurs because the valve that allows the solution to flow gets "sticky" and will not close. The valve is engaged by the trigger mechanism in the handle. Squeezing the trigger pushes downward on the valve's plunger, but the spring in the valve that is meant to push the plunger back up to the closed position is not capable of doing so.
Here's the solution:
This valve is white and resides about half way down the vertical handle portion of the cleaner. To get to it, unscrew the 2 black screws that hold the top part of the handle to the bottom part. These are the same screws that you used for assembling the cleaner when you first bought it. Pull the top portion of the handle up and it should slide out.
Now, looking down into the handle body of the remaining portion of the handle, you'll see the top of the white valve. If you push down on the top of the valve (like the trigger mechanism in the top part of the handle you just removed does) it may go down some, but it probably won't go back up by itself like it should.
I found that lubricating this plunger with dish soap was the trick. If you can't get enough access to the valve to do this, you can remove the seven phillips head screws in the lower portion of the handle and pry it apart. I did this. I even took the valve out and put soap around the plunger and into the valve itself. I worked it up and down until it had a quick and positive open/close action.
Reassemble and you should be good to go. You'll notice that the trigger now has a more positive feel to it. I hope this helps.
open case to access behind trigger the problem probably lies with the small valve that it operates. Remove valve and blow through it pressing the operating button in and out to see if it closes off fully.If not replace valve and reassemble.
The problem was a clogged heating unit which is located in the lower handle. There are two clear hoses going up the inside of the left leg of the lower handle that go to the heater and to the in-line water switch all within the lower handle. I unplugged the metal heating unit water lines and electrical connections (label the connections as you take them apart if you have a hard time remembering things...there were seven connection in all be it water and/or electrical). Removed the heat unit out and then removed the 6 screws holding the heater cover. Inside was a white powdery pasty debris (lime deposit ?) and the water path was clearly blocked in four different places. I cleansed the water trough with a little water and soft toothbrush and several toothpicks then reassembled. If you need new washers go to Orchard or ACE hardware. Take the old rubber washers(they are red) with you for comparison. I didn't need new washers...I just gently cleansed them. I immediately ran clear water through the machine and actually cleaned the carpet with a water rinse only. Will go back and finish the carpet the right way tomorrow. I had only used my machine three times before this happend over a three year period. A friend told me to always rinse it two maybe three times with clear water after using it and before storage. This took me exactly 42 minutes to disassembly and reassemble. Cost savings is several hundred dollars since I have a 5 bdrm house and would need a professional cleaner to do the small dirty traffic lanes all around the house.
