Maybe it over heated or the hose was jammed. Unplug it for a few minutes, check the hose for any stuck debris, then plug it back in. Shop vacs also come with a filter. If the filter is too dirty, it might have shut off as a safety precaution to not cause a fire. Follow directions to clean the filter. Hope this helped. Dee

I don't know exactly but if it has one it will usually be found in intimate contact with the motor.

Some vacs were fitted with a bimetal breaker which is also sited close to the motor, but sometimes there is so much dust around once they open they fail to make a good contact again when the cool and close.

Older vacs weren't fitted with any safety devices.

Yes, you need to take it apart. Maybe ask a friend who knows Mechanics or Electrical.

Most wet dry vacs have a ball float that blocks the vacuum when it is full of liquid. Yours sounds as if it is full or the ball has gotten stuck in the up, or blocking position.

Absolutely yes. If not, the filter will be saturated with water and ruined.

First check if the bag is full. Then check if hose is clogged or attachment is clogged.
