The answer first
On a Magic Chef dishwasher a leak is usually at the door seal or the supply fitting, or it is foam rather than water at all. The first checks below need nothing but a torch and a sheet of paper. A tub or pump seal is the last entry on the list.
What you are seeing
- Water running down the front of the door — The door seal, a door out of alignment, or foam lifting over the seal.
- A puddle emerging from under the front of the machine — Water tracking along the base from a hose, the pump or the tub — it emerges at the front whatever its source.
- NEAR MISS — the cabinet beside the machine is wet but the floor is dry — Look at the supply and drain connections in the adjacent cupboard before suspecting the machine.
Causes, most likely first
- Detergent, foam and overfilling — Washing-up liquid in the dispenser, or far too much dishwasher detergent, produces foam that climbs past the door seal and out of the vent. The floor gets wet, nothing is broken, and it happens again on the next cycle with the same dose. This is the one to start with: this machine is dosed by hand and by eye, and an overdose produces a leak that no amount of seal-checking will explain. Magic Chef is a long-standing budget brand: parts exist and are catalogued, but the unit's replacement cost is low enough that the repair-or-replace line arrives early.
- The door seal or the door alignment — The seal around the door catches debris, hardens with age and splits at the corners. A door that has dropped, or one that is not latching square, holds the seal open at one point and lets water past there on every wash. It follows immediately: it explains the leaks that appear down the front of the machine during the wash.
- The machine is out of level — A dishwasher tilted forward spills over its door lip; one tilted back holds water where it should not. Machines slid into a cabinet run often end up sitting on their front feet with the rear ones short of the floor. Third: it is the least common of these but it is quick to eliminate.
- The pump seal, a hose inside the cabinet, or the tub — Water that arrives from the centre of the underside, that appears only during the drain, or that leaves a rusty trail has come from inside the machine. None of those is an owner repair, and a corroded tub usually ends the appliance. Fourth: it is the least likely and the most expensive, and on this class of machine a tub leak is rarely worth repairing at all.
Work through it in this order
- Look at whether the water on the floor is foamy — Foam rather than water is detergent every time, and no seal in the world holds back foam under pressure.
- Run a finger along the seal and close the door on a sheet of paper — A hard, cracked or displaced seal is felt as easily as it is seen, and paper that slides out freely marks the point that leaks.
- Put a level across the door opening and along the base — A machine tilted forward will spill over the door lip at the end of a fill regardless of how good its seal is.
What an owner can safely check
- Run one cycle with the correct dose and nothing else added — Never put washing-up liquid in a dishwasher. If the floor stays dry, the dose was the fault.
About 60 min
- Clean the seal and the door face, and check the door closes square — Warm soapy water, then feel for splits at the lower corners where they almost always start.
Tools: cloth, torchAbout 15 min
- STOP before pulling the machine out of its cabinet run to chase a leak — The hoses and the cable are short, and a machine pulled out on a wet floor is a hazard in itself.
Before anything comes apart
Safety
Unplug the machine or switch off its breaker before removing a panel, and shut the water off at the valve under the sink before disturbing a connection. Let the machine cool before reaching into the tub — the element in the base holds heat well after the door is opened.
Where the owner's part ends
The owner's part covers the door seal, the fittings, the dose and the levelling. A pump seal, an internal hose or a corroded tub is a service call, and a leak left running damages the floor and the cabinets long before it damages the machine.
