The short answer
Water on the floor around a SPE dishwasher is a door problem, a detergent problem or a connection problem far more often than a failed tub. The thirteen codes in the table cover more than one build generation, so match your own code against it before a panel comes off.
What you observe on these models
- Water at the door sill, on the floor in front of the machine — The seal, the door alignment, or suds. Look for foam at the sill: foam means detergent, not a part.
- A stain on the cabinet side or the floor beside the machine — Drain hose connection or air gap overflow. The water arrives from above and runs down the cabinet wall rather than out of the tub.
- The leak only happens on longer or hotter cycles — Heat and time expand seals and raise water level. A seal that is marginal leaks on the long cycle and passes on the short one.
- NEAR MISS — water standing inside the tub, floor dry — That is drainage, and it has its own page for this family.
Causes, most likely first on the SPE family
- The door seal is hardened, torn or out of its channel — Ranked high on a family whose codes span several generations, because the seal is the part that ages fastest on any dishwasher: it goes hard, takes a set, and stops closing on the tub lip.
- Over-sudsing from the wrong detergent — Checked early because it is free, instant and common: hand dish soap in the cup, or a heavy dose in soft water, foams until the foam finds the door.
- The sump gasket, heater seal or pump seal is passing water — Moved up on an older family: these seals are under the tub, they leak only under pressure, and their symptom is a wet toe-kick during a cycle and a dry floor afterwards.
- The drain hose connection or the air gap is overflowing — The clamp at the disposal loosens, and a silted air gap spits water onto the counter and down the cabinet side.
- The tub seam or a spray arm feed has split — Last and least common, but it is the cause that ends the machine: a corroded seam or a cracked feed cannot be sealed and the repair is rarely economic.
Check in this order, and why
- Dry the floor completely and put paper down — A sheet of kitchen paper across the sill and another under the toe-kick turns an invisible weep into a dated map.
- Run a short cycle and watch the first ten minutes — Stay with it. A leak that starts at fill is the supply side; one that starts at the wash is the door or the sump; one that starts at the drain is the hose connection.
- Look for foam before you look for a part — Foam at the sill means detergent. Run one rinse-only cycle with nothing in the cup and confirm the floor stays dry before you buy anything.
- Work round the door seal with a finger and a light — Feel for hard sections, tears at the corners and any length that has lifted out of its channel.
- Only then look under the toe-kick — Power off, panel off, torch in. A wet clamp, a wet sump seam or a stained pump body names the part — and names a job that needs the machine unseated.
Models in the SPE family — Some codes here are pinned to a single build and the rest are patterns covering several, so match the longest entry that fits the tag inside your door frame. The thirteen codes fall into three leading groups, and that spread is the reason this page is written for the family rather than for one machine.

Before you open anything
Safety
Switch off the breaker before anything goes under the machine, and close the supply valve under the sink before you disturb a fitting. A capacitor can hold a charge after the power is off.
When to call a technician
Detergent, the door seal, the door alignment and the fittings under the sink are yours on these models. Anything that only shows itself as a wet toe-kick during a cycle is not: that is the sump, the heater seal or the pump seal, and the machine has to come out of the cabinet.
