Detergent container will not despense fluid

I have stuck a connection to the Bissell ProHeat series cover extractor fix guide underneath. This guide resembles my Book of scriptures while I'm dealing with these machines, and is Very useful on making sense of how, and where hoses and parts go, and potential clarifications of issues, and how to fix them.

http://www.hoover.com/pdfs/manuals/F7452900.pdf Heres a link to the manual if you dont have one, Ive emailed them and they gave me the same solutions that are on page 17. ? Make sure tank is securely locked in position ? Clean water tank or detergent container empty ? Refill container according to instructions for surface being cleaned ? Recovery tank lid not on correctly ? Make sure lid is firmly in place ? Valve cap clogged ? Remove and clean valve cap (see following instructions) 1. Remove clean water tank. 2. Turn valve cap (A) counterclockwise and remove. Soak valve cap in warm water for at least 15 minutes. Wipe cap dry. 3. Align slots (B) on cap with tabs (C) in opening. Turn cap clockwise to tighten.

Similar problem still looking for a solution...
I observe that if I press down firmly on the clean tank while pulling the trigger, that it dispenses the correct volume of solution, but that's an awkward action to do while also doing the wet runs back and forth.

Your heater may be clogged up with soap gunk. The water for the hand tool does not go through the heater.

YES! And it was amazingly simple. The soap dispenser has a red washer/gasket thing that fits over the nozzle. For clarity, it can be viewed here: http://www.vacpartswarehouse.com/Products-p/2036677.htm
The red part can come loose and remain inside the receiver where it fits snugly and looks like it belongs there. In this configuration, the tank cannot insert far enough into the receiver to open the spring valve and no detergent will flow. Simply remove the red piece from the receiver (I used small pliers), replace it on the tank nozzle, and the detergent will flow again!

Check the spring loaded valve at the bottom of the detergent bottle.
Push it up with your finger or a pencil or some such thing and see
if fluid comes out. If it does, then the problem is the valve or tubing I
would suspect.

Under the detergent side, there is a metering plate,(located on the machine) which can be removed. ensure that this is installed. have you verified whether the machine will dispense detergent only without any water in the water tank?

Is the detergent tank cracked at the bottom, under the black seal? If so the whole tank asm. needs to be replaced. But if this is new, then it has a one years warranty on it and you can take in for warranty repair.

I'm assuming the belts are OK.... Your heater is clogged. Unplug the machine and let it sit for 30 minutes. Take the handle apart, there will be a 4 inch by 8 inch metal box inside. This is the heater. Remember I said to let the machine sit for 30 minutes? If you didn't, the heater may be EXTREMELY hot!! Disconnect the two hoses going into it, and clean the metal pieces out (that the hoses connected to) with a needle or very small drill bit. You may want to remove the 6 or 8 screws holeding the heater together and remove the cover to clean it out. Reassemble and fill both tanks with VERY hot water ONLY and run the machine to rinse the entire system.

To prevent future reoccurences... use only Bissell extraction shampoos. Never put anything in the detergent tank except shampoo. (And only water in the water tank) Mixing chemicals with anything else turns the water/detergent mix to sludge. Also, when finished shampooing, put ONLY water in both tanks, and run the machine until one of the tanks run out of solution. Doing this rinses the hose lines out and prevents hardening of the solution in the heater ports.

I've fixed these machine for years. No dispensing is almost always the heater clogged.

I have a similar model and occasionally have problems with water/detergent flow. I find it is generally due to an airlock in the piping caused by forgetting to turn the deregent water control off before removing the detergent container. Follow the manual instructions. Turn the knob to off. Fill both containers. locate them carefully. Make sure filters in the water tank and in the flow meter are clear. Start machine with handle laid flat and knob turned to maximum flow.
