What this usually is
On a Maytag dishwasher, water on the kitchen floor is most often a spray arm fouling a load item and spraying at the door seal rather than a cracked tub, sump or a failed pump seal. The mechanical and blockage causes come first, because on a platform this common the pattern is known: the parts that move and the parts that carry water. The first two checks below are owner work and need no part; the third is a service call.
What the owner observes
- A damp cupboard base beside the machine — Water tracking sideways under a floor is how this damage stays hidden.
- Water at the back of the cabinet — The back is where the hose connections live.
- It leaks only on some programmes — A programme-dependent leak follows water volume and temperature.
- NEAR MISS — the dishes are wet but the floor is dry — Poor drying is a different fault and not a leak at all.
Why this happens, likeliest first
- A spray arm fouling a load item and spraying at the door seal — A tall item stopping the arm, or a nozzle blocked so the jet runs in one direction, sends water straight at the door seal instead of round the tub, and it overwhelms a gasket that is otherwise fine. It leads because the loading habit is what changed, and this machine is usually loaded to capacity. It is a fitted kitchen appliance, plumbed and levelled when the kitchen was built and rarely touched since.
- Foam from the wrong detergent or a rinse-aid overdose — Hand-washing liquid in a dishwasher, or a rinse-aid dispenser turned to maximum, creates a foam volume the tub was never designed to hold. It climbs out at the door with nothing broken at all. It ranks here because a single correct-detergent cycle is a decisive free test.
- A cracked tub, sump or a failed pump seal — A cracked sump or a pump seal that has given up puts water under the machine with the door and the hoses all dry. It arrives from underneath and it needs the machine out to reach. It is last because it is the only cause here that is not owner work.
What to check first, second, third
- Spin both spray arms by hand before starting a cycle — An arm that fouls a load item sprays where it should not. First, because it is the likeliest to end the job.
- Check which detergent is in it and where the rinse-aid is set — Hand-washing liquid, or rinse aid at maximum, makes foam that no tub can hold. Second, once that is clean.
- Look underneath with a torch during a wash — Water arriving from above inside the cabinet means the machine has to come out. Third, and by now the answer is usually in hand.
The owner-side checks
- Clear the spray arm nozzles and reload so nothing fouls them — A cocktail stick clears a blocked nozzle in a moment.
Tools: cocktail stickAbout 20 min
- Run a rinse cycle to clear the foam, then correct the detergent — Never use hand-washing liquid, and turn the rinse aid down.
About 30 min
- STOP — note where the water appears and book the visit — An internal leak needs the machine out, and that is not owner work.
- STOP — note where the water appears first — Where it arrives is most of the diagnosis, and it costs nothing to record.
The part that is not optional
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Close the water supply valve under the sink before opening any fitting: water arriving under pressure into a cupboard does more damage in an hour than the repair costs.
The line between a fix and a call
Call when the water arrives from underneath with the door and the hoses dry, or when a leak returns after the gasket, the detergent and the level have all been dealt with. Everything else on this page is owner work. On this brand parts are available, documented and priced sensibly, so the repair-or-replace question usually answers itself in favour of repair.

This page is written for the appliance class, not for one Maytag model line. Where a family- or model-specific page exists it is the better answer and it is linked below — go there first if your model is named. Not here: gasket profiles, sump layouts, hose routing, or part numbers.
