Error code MECH-04 on the Hotpoint HDA3600HWW 24 in Built-In Dishwasher with 48 dBA Noise Level and 5 Wash Cycles means: Leaking Water on Floor. Water puddles on the floor in front of or underneath the dishwasher — inspect the door gasket around the entire perimeter for tears, compression, or food debris preventing a seal; the gasket is a rubber or vinyl strip that clips or slides into a channel on the door; check the inlet fill hose connection at the water inlet valve for drips; the pump seals can leak if the pump motor bearing is worn (listen for a grinding noise during wash); also inspect the tub itself for hairline cracks especially around the heating element grommet and spray arm bearings
