yes this one is defective indeed.
there are flappers with seals inside that sense this condition
it should not be causing this unless there were really a clog
i can hear those flappers when i turn it off
so what do i do
since this is so new, simply exchange that one, these are typically very good vacuums
we all get a bad device from time to time
it may have been dropped during shipping, usually that is the cause
there is nothing I can do to clear the clogg?
you would need to take the whole thing apart to fix this, and likley there is broken plastic tab in there
I seriously doubt there is a clog that is causing this;-)
ok... npow I just have to find the receipt lol
