I'd be happy to walk you through this repair. Unfortunately this is a very common problem with the Hoover SteamVacs.
Here's what you'll need to complete this repair:
- Hoover Turbine Assembly For Model F5866-900 Part # 43191001 or 90001354
- Phillips Head Screwdriver
- Flat Head Screwdriver
Step 1. Remove both the clean solution, and the dirty solution tanks from the machine, and press the handle release pedal so that the handle is laying down flat:
Step 2. With a flat head screwdriver, pry off the rotating brush speed indicator knob:
Step 3. Unscrew the silver screw that's at the very top of the see thru suction port where the dirty solution tank rests.
Step 4. Turn the SteamVac upside down so that the brushes are facing upwards. There are four clips that hold these brushes in place. You'll need to remove the brushes from the machine by squeezing the four tabs while pulling upwards at the same time. The picture actually only shows the two tabs on the right hand side being squeezed, but the tabs on the left hand side are in the exact same location:
Step 5. Once you've removed the brush block from the machine, there are 4 screws on the bottom that need to be removed. Keep the two silver screws on the very corner in place, you won't need to remove these. Remove the four screws that I've highlighted in red:
Step 6. Turn the machine back over right side up, so that the brushes are on the bottom. There are two clips that hold the top housing in place. Insert your flat head screwdriver in between the top and lower housing in the rear of the machine close to the rear wheels, and pry upwards to unclip these clips on both the left and right sides, then remove the top motor housing from the machine.
Step 7. You'll now have complete access to the turbine. Remove the two silver screws in the front of the unit that hold the turbine in place, as well as remove the front hose from the turbine:
Step 8. Once you have removed the two screws you'll be able to lift the turbine up. There's a second hose in the rear of the turbine that you'll also need to remove before you can remove the turbine completely. After you've removed the hose, take the turbine out of the machine. You'll notice to the immediate left of the turbine other hoses that connect to a black circular part. This is actually the pump that sprays the water on the floor. If you ever have the problem where the clean water solution will not spray, it's a good possibility that this part needs to be replaced.
Simply install the new turbine, reattached the hoses and two front screws. When you're putting the top motor housing back on the unit, make sure that the brush speed selector knob that's on the right side of the turbine fits through the **** in the top motor housing. Also before tighting the two screws that that hold the top housing in in front of the brushes, there's two clips. You'll need to snap the top motor housing behind these two clips. Simply push front of the motor housing until you hear it snap into place.
