checked over Dishwasher unit, found same fuse blown. traced all wires associated with that fuse. found water in pre-wash float box. found coming from drip/leak in table attached to unit. advised maintenance to repair table and add a leg in its place on table. drained electrical box and repaired damaged wire and tested okay. closed up unit and advised maintenance I left float box open so it will not fill up again and that they will need to close up after leak is resolved. will order float and replace due to possible unforeseen issues it may have to being shorted out numerous times. looked up part number and found it is no longer available.
