The short answer
Water on the floor around a GV dishwasher is a door problem, a detergent problem or a connection problem far more often than a failed tub. The seven codes in the table share the family stem and sit close together in build, so the layout described here holds across them.
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.
- Foam or suds visible at the bottom of the door — Hand dish soap, or far too much detergent, or a rinse-aid spill.
- 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 GV family
- Over-sudsing from the wrong detergent — First on the list, and the most common cause in a household that is new to the machine.
- The door seal is hardened, torn or out of its channel — Second. Run a finger round the whole seal: a section standing proud of its channel, a tear at a corner, or a flat spot where the door has sat closed for years all leak in the same place.
- The door is out of alignment or the latch is not pulling it in — It ranks here on a narrow family because misalignment is usually introduced at installation — an out-of-square cabinet opening, or a panel fitted without resetting the hinge tension.
- The fill valve or its supply fitting is weeping — Ranked here because a fitting disturbed during installation is the classic source of a leak that has been there since the machine arrived.
- The tub seam or a spray arm feed has split — Last, and genuinely rare on units of this age. Reach it by elimination, never by assumption.
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.
- 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.
- 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.
- 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 GV family — Each code here is pinned to a single build, so match the tag inside your door frame character for character. The seven codes fall into five 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.
