Question about Hoover U6434-900 Bagged Upright Vacuum

2 Answers

Power will not switch off. The switch will turn the vacuum on but when you are finished vacuuming, the control will not turn it off. I removed the handle and worked the red on and off switch by hand and there is nothing wrong with the physical switch. the problem is with the plastic depressor that slides over the switch. How do I fix it?

    What I did was take the handle off and reinstall in the off position, works perfectly now. I read somewhere else to reinstall in the on position but that did not work.

SOURCE: How to remove handle from Hoover 5445-900 upright wind tunnel vacuum

Hoover.com doesn't have a manual specific to your model but there is one similar which will show how to remove the upper handle from the body.

http://www.hoover.com/pdfs/manuals/U5467900.pdf

Do you have a replacement switch? If not I believe you can buy one from Hoover (the switch and/or the upper handle assembly). Unfortunately your model isn't listed on the website, is this a new vacuum? I recommend giving them a call, that would be the easiest way.

Also remember when working with electronics to unplug the vacuum. Even when there is no power residual electricity can remain in the wires. If you feel unsure, take it to a repairman.

Hope this helps!

SOURCE: Brush won't spin when position of handle changes

The belt for this machine is very specific and only one size fits. It is not uncommon for vac shops to sell the wrong belt because the proper belt is not available from normal supply houses, so they will substitute something they think will work.

Also, assuming you do have the right belt, check the tension arm that drops down on the v-belt when the handle is brought back. This arm has a wheel/bearing with a plastic "tire" or trim that rolls on the belt to tighten it. Sometimes, this tire cracks and falls off and then the remaining bearing won't have the necessary tension to tighten up the belt.

SOURCE: Vacuum doesn't work when main attachment is on....

S3765-040, power head would not run when the handle was elevated. Problem was with wiring from connecter plug on power head swivel into the power head itself, because of the design the wire tends to develop a short. Test it by turning on the vacuum, elevate the handle, then when it stops running move the visible part of the wiring with you foot/hand. If it starts/stops then you have a short. Replacement part was about $10.

Hoover emailed me back right away with a solution and a thorough explanation for a very easy fix. I guess I should have thought of that myself. Oh well, but that did not cost me anything. Now that makes me happy.

Won't turn off


It's highly probable that the Dyson power switch has gone bad.
You can buy dyson dc14 switch here.
The switch is located right behind the front covering of the neck or handle when you remove the telescopic wand. Please make sure that the vacuum is unplugged before you start this project.

Hello,

This is a clear indication that your on/off switch is probably gone bad. What happened is probably the handle latch was not properly installed when you replaced it. No worries though, I have written a clear, easy to follow guide on how to replace the on/off switch on your Hoover Windtunnel Self-Propelled upright.

What you'll need to do this repair:
- Phillips head screwdriver
- Needle Nose Pliers
- Hoover Windtunnel Switch For All Upright Models

Step 1. Turn the vacuum cleaner around so that the back is facing you. Remove the two screws at the top of the vacuum that are holding the handle on the machine. Please see the picture below of the two highlighted screws that need to be removed;
b37b5a3.jpg

Step 2. After these two screws have been removed, simply slide the handle backwards, and remove it completely from the vacuum and set it aside. You now can see the on/off switch, but you can't easily change it from here, you'll need to complete several other steps before you can remove the switch. Here's what the vacuum should look like after removing the handle:
1aabeee.jpg


Step 3. After removing the handle from the vacuum, turn the machine around so the front of it is facing you. Open the vacuum bag door and set the door aside. Also remove any attachments that are on-board in the tool storage bin, this model has a hand-held turbo brush stored here. After removing both of these parts, you'll need to unscrew 3 screws that holds the tool caddy onto the vacuum cleaner. I have circled the area where these 3 screws are located:
32822fa.jpg


Step 4. After removing these three screws, pull the tool caddy off of the vacuum by pulling straight forward by using the tool caddy lid. You'll now have access to both the front and the back sides of the switch. Use your needle nose pliers to remove the two wires that are attached to the switch. Be careful when pulling these wires off because if you pull too hard, then it will break the switch terminal off inside of the wire. Most models have the wire that has a plastic covering over the end of it on the top, and the metal terminal is connected on the bottom. The two lead wires that need to be removed are highlighted:

8c3008f.jpg


Step 5. After the wires have been removed from the switch, turn the vacuum back around so that the back of the machine is facing you. Simply use your flat head screwdriver to pry the switch off. You may push on the back side of the switch where the wires connect to it in order to give a space so that you can get a screw driver behind it. Here's how it should look:
d700e4d.jpg


Step 6. Once the old switch has been removed, simply push the new switch into the open hole. Important: Make sure that the Off setting of the switch is at the bottom, and the part of the switch that says on is on the top, otherwise the switch will be reversed. Re-attach the wires to the switch, with the wire that has the plastic covering on top, and the metal wire terminal on the bottom. The only tricky part of reassembling is when you put the handle assembly back on the vacuum. As you can see, there is a metal cable below the switch. This metal cable controls the self-propelled mechanism. If you look at the handle assembly, you'll see where the self propelled cable sits inside. The easiest way to line these up is to pull the cable up to the top, and then line up the rod inside of the handle that the cable goes in, and slide the handle back on the vacuum.

I hope this was helpful.

I have a Dyson vacuum. The vacuum won't stay


My vacuum had this exact same problem, but was out of warranty because it was remanufactured. Thankfully, it's a very quick, five-minute fix.
  1. UNPLUG The Vacuum!
  2. Remove the cannister.
  3. Extend the handle and remove it.
  4. Remove the two torx (T-15) screws behind the power button, where the handle normally stows.
  5. There are four tabs holding the front plate containing the power button on; use your screwdriver to release them.
  6. Gently pull the front plate off.
  7. The switch on the right is the power button. Remove it, try clicking it a few times; if it sticks, great! Replace it and reassemble, otherwise you'll need to replace it.

My vacuum died. It won't turn on. It is not the outlet. Is it a blown fuse? How do I replace the fuse? Where does it go? This vacuum is a little over 2 years old. My older Hoover WindTunnel STILL works and...


It's probably the power switch. My switch was dicey for a couple years, finally gave out. Easy to replace.

Remove the two screws just above the WARNING on the rear of the upper handle assembly, then slide the whole assembly to the rear of the vacuum.

Remove the dust bag cover. You will see two holes just above the upper corners of the dust bag. Remove the screws from these recessed screw holes.

Open the furniture cleaner cover and remove the cleaner attachment. Remove the single screw that was hidden behind the attachment. Then remove the attachment housing by pulling it towards the front of the vacuum.

Inside you will see the rear of the power switch. Pull off the power wires (don't worry, easy on/off male/female connectors, no soldering).

The switch is held in by tension bars at the upper and lower rear of the switch. Firmly press down on one of both of the upper/lower tension bars, and push the switch through the housing from the rear of the switch.

Replacement part number is 28161067, about $2.50. Shop will charge about $85 to repair it themselves.

Unplugged while unit was on by mistake and now it will not turn off with switch


it sound like you have pulled the wire to tight and it has shorted the switch inside the vacuum, so the wires are connecting, to cure this unplug from power supply and remove the cover to the switch and relocate it into its slot where it should originally should go, of course the housing to which the switch locates may now be damaged, but you should be able to stop the wires from touching and this will let you work the vacuum properly

secure the cable again where it comes out of the machine
