How do you change the power cord on the Hoover u5475-900 Wind Tunnel 6200? Thanks for your help.

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.
