Just a thought, but there may be an air lock preventing an empty tank from filling fully, so I would turn on a hot water faucet and make sure a full flow of water is achieved before declaring that the tank is full.
Also, when not in use, I keep a piece of tape over the 120VAC switch in an off position. This ensures that I don't accidently leave it on and hook up 120V power even for a second.
We do run the farthest away faucet until a steady flow/no more air and we do also tape our switch as it is in a very bad place where it can be accidentally bumped
