u5757-900, Hoover mach 4.7 vacuum: The power cord connects at the top of the machine, literally right behind the entry point of the cord. You don’t have to take any of the rest of the vacuum apart. I found that out after I did take the entire machine apart. The wires can be connected with pressure connectors.
Overheating can be caused by: - running the saw on a long, low-guage extension cord or with a damaged power cord. Eliminate extension cords or replace with heavier cords, at least 12 guage or better. Replace power cord if damaged. - too much "stuff" packed in and around the armature and field so air cannot curculate and cool the tool. Blow out the body. - broken, worn or seized armature bearings. Check/replace if needed. - broken, worn or seized transmission and blade arbor bearings, usually caused by low or no oil in trans case, check and replace as needed.
1 Unplug the vacuum and remove all accessories such as extensions and brushes. Open the vacuum's outer casing to get at the end of the power cord. Exactly how you will do this depends on the model of vacuum. Generally it simply involves the removal of two to three Phillips-head screws.
2 Follow the power cord to the two connections at the vacuum's motor. Unfasten any clips or holding bracket and disconnect the cord from the motor. Sometimes this can be accomplished by unscrewing two connection screws, other times the cord is soldered directly to the motor. If this is the case use wire cutters and cut the cord about 4 inches from the motor to give room for splicing on a new cord.
3 Insert the new power cord into the vacuum. Follow the exact same path as the old one. If there were any brackets or clips that held the old cord in place inside the vacuum or out use them on the new cord.
4 Tie a knot in the cord on the inside of the vacuum casing so that it will not accidentally be pulled out of the motor once it is in use.
5 Connect the new cord to the motor in the same fashion as the old one. With wire strippers take off about 1 inch of insulation from the new cord to expose the two wires. Either wrap them around the connection posts and re-screw, or twist the new cord wires around the 4-inch remnants of the old cord and seal all exposed wire and connections with electrical tape.
6 Replace the vacuum's casing in reverse order from how you removed it. Plug in the vacuum to test.
Hi,
Try this: Unplug the power cord from the back of the printer. Then, unplug the USB from the back of the printer. After a minute, plug the power cord back in. Let the printer boot up for a minute. Then plug the USB in again. Let the USB get connected. If you don't see any errors and you setup your printer, then that should have reset the "other operation".

This procedure worked for replacing the cord on my Hoover U6425-900. At a minimum, you will need a number 2 Phillips screwdriver, wire cutter, and two electrical wire nuts and electrical tape. Remove the accessory tools from the storage compartment. Remove two screws, these are recessed. Remove the cover from the bag compartment, remove two screws located at top corners of bag compartment. You may have to open the side filter door but the accessory tool storage compartment should be free at this point and can be removed. You should see the power cord and related wiring. If you have a digital camera you could take a photo at this point in case you need a point of reference. Make note of the power cord strain relief routing and length of wire. Too much wire will make reattaching the storage compartment difficult and the routing prevents the cord from being pulled out.
On my model the wiring colors were purple, orange and white. My replacement cord had black and white wires. The orange wire will not be involved in cord replacement. Using the wire cutters clip the purple wire about three inches back from the existing terminal. If present, clip the two nylon wire ties and discard. The white wire will have a crimped on wire connector. Clip the white wire about three inches back from the existing wire connector. The old power cord can be removed by pulling it out from the rear, it should just slide out of the rubber insulating boot. If not use a set of pliers and crimp the boot from the wiring side and push it outside the vacuum housing. If you have to do this make sure you slip the boot over the replacement cord before you insert the new cord back into the vacuum housing. Remove about a half inch of insulation from the purple and white wires and from your replacement cord unless it was supplied with insulation already removed. Use new wire nuts and connect the white wires. Use the other wire nut and connect the purple wire to the remaining new power cord wire. Use some electrical tape and wrap the nuts to the wires a couple of times so they won't loosen. Make sure you route the power cord around the posts as this is the strain relief and prevents the cord from being pulled out. Reassemble and test.
Remove the cover plate just above where the cord goes in (1/4" screw) Loosen all 4 screws (3 brass ones and a green one) and see if the connectors will come off. (this is for a "fork" type connector) if the connectors won't come off, you have a "loop type connector in which case you will need to remove all the screws completely. BE CAREFUL! If you drop one inside the machine, you will have to dis-assemble it. Now, re-install/ tighten down the green screw. (If the green screw wasn't used, the unit wasn't installed correctly at the time of install). Loosen the screws on the clamp where the power cord comes into the washer. (again, they may be missing do to improper install). Now, install you three prong cord in reverse. (The cords are flat so you can't mix the wires up on most models of cords) Make sure to put the clamp (strain relife) on that was supplied with your new cord.
