It will not dispense water when you press the release button

Keep pressing the water button to primer the water through the hose

The valv is probably faulty. Check also that the water duct to valve is not clogged

It's losing pressure due to the leak. need to fix the leak first.

Check the release valve on bottom of clean water reservoir unscrew if needed, once again if your not sure run hot water in the solution tank through the system to help remove old soap residue and always run hot water through to prevent future problems after cleaning carpet and storing.steve

Check these items:
(1) When the trigger is pulled, does the rubber pad behind the tank seal on the handle get pressed down? A rod in the upper handle presses this rubber valve to dispense water/soap.
(2) Are any hoses kinked closed at the bottom pivot point of the lower handle, where attached to base?

put it on the curb

Listen to see if you can hear pump run when pressing button, if the pump does run, than either you have a clogged nozzle or screen in water fill compartment.

Check the bottom of the tank, there should be a gasket on the valve at the bottom of the tank. Must be on the tank and not sitting in the hole. Make sure the tank is sitting firmly and not off set even a little. Loosen the cap for the flow indictor while running, then tight when fluid starts leaking out, stop when the spinner starts spinning. Other then that you may have a clogged line somewhere.

When you press the trigger an angled piece on the end of the plastic rod attached to the trigger pushes valve button in that then releases fluid. On releasing the trigger, the valve button is supposed to be pushed back out by an internal spring. The button gets sticky with evaporated cleaning fluid and does not come back out, causing fluid to continuously run. Try taking the machine outside, fill the tank with very hot water, pull the trigger, and let the clean, hot water flow through the valve. Perhaps it will free up. If not, the valvle will have to be replace. Either way, once it is working, ALWAYS flush the entire system with hot, clean, clear water to remove any cleaning solution in the system or it will only clog again

This could be due to dried out soap in the works below the dispenser. Try cleaning the hole, putting plain water in the soap dispenser to clean it out further. You could just put some soap in with the water. Be sure to run lots of rinse water through afterward to clean out the heating unit.
