I used it a week earlier w/o problems. The following week I plugged it in and it turned on. I turned it off and came back to it a few minutes later and it no longer works. There's no feedback at all when I press start (no sound or any other indications it's "trying" to do anything). Any suggestions?

Here is a picture of the dome taken apart, not too hard, take out the 3 screws on top, then the pic should show the rest.

If you remove the motor, you will see that the wires that go from the switch to the brushes. On one side there is one wire connected directly to the brush. On the other side the wire goes to a plastic plug with a second wire going to the brush. This is probably where the problem is. This is a fusible link and it has most likely melted creating an open in the circuit. I put a piece of solder where the link was and the motor ran BUT the brushed arced like a sparkler. Upon further examination the brushes were crumbling apart. I have been unable to find replacement brushes.
This machine has a five year warranty. I called Shop Vac Customer Service 1-888-822-4644 and they sent me a new motor.
I had a Shop Vac QL50EIC which had exactly the same problem but the warranty was expired so that I had to buy another motor for about $50.

These problems are nearly exclusively caused by a bad circut board and replacing it is the fix. Bad boards can cause many different effects so its nearly impossible to be sure. The 9v signal wire is not enough to short out an entire unit so it is unlikely the hose. If it is a direct connect system and you are pulling power from the 110 somehow that would cause main unit problems but that is unlikely at best. Sounds like a failed board to me.
Best of Luck

Yup! Clogged hose on the back of the cannister! Unit is designed to shut off for 30 minutes when this happens to protect your motor. Remove top of hose where debris enters the cannister through a filter above it, then remove the other end of the hose from the bottom of the back of the cannister, take it outside and use something long that'll fit inside the hose to force out all the clogged debris and hair through the top of the hose.

I just picked up a similar model someone was throwing away. turns out there is a thermal fuse inside the motor housing that blew. I just need to find the values of the fuse and repalce with appropriate size. motor runs when fuse is bypassed.
