Everyone has those days once in awhile. The key is to NOT do it
next time.

There was a post on the other board about a
vibrating filter and the person couldn't figure out what it was.
Turns out it was the containers (food or something) placed on top
making the rattling sounds. Another one was a clicking tink sound
coming from the tank. That turned out to be a canister output
current aimed at the metal thermometer.

So your not
alone with odd equipment happenings.
