In brief
The first thing to rule out on a Fisher & Paykel dishwasher is the top cause below — the door seal or gasket — and the second is the water supply connection or the inlet valve. A dishwasher leak is either coming from the door seal, from a plumbing connection, or from an overfill, and the timing plus the location narrows it to one of those three quickly.
Symptoms, and the ones that mean something else
- Water only when the sink is used — The drain connection or the air gap rather than the machine.
- Water at the front, under the door, during the wash — The door seal or the door itself, which only leaks when water is being thrown at it.
- One drawer works and the other does not, or a code appears on the drawer panel — A double-drawer machine is effectively two machines, and that comparison is the best diagnostic tool on the appliance.
- NEAR MISS — a puddle after opening the door mid-cycle — That is condensation and carry-over rather than a fault.
Ranked causes on this platform
- The door seal or gasket — Ranked first on a Fisher & Paykel dishwasher because the drawer lid seal and the door catch are the signature service items on this architecture, not an afterthought. A gasket that has hardened, torn or come out of its channel leaks at the front only while the machine is spraying.
- The water supply connection or the inlet valve — Second here: the filter stack is designed to be owner-serviced and is the first mechanical thing to look at.
- An overfill from a float or level fault — A stuck float lets the machine keep filling until water reaches the door seal and comes out of the front.
The order to work in
- First: Run a finger around the whole seal for gaps and hardening, and look at the lower corners where they usually fail. — It sits first because the drawer lid seal and the door catch are the signature service items on this architecture, not an afterthought.
- Second: Dry everything and check whether water still appears with the machine idle — that answer is definitive. — Next, and it needs no tool.
- Third: Watch a fill and note whether the water level rises above the normal mark. — Only once the checks above are clean.
What an owner can safely check
- Compare the two drawers, and read the code the machine is showing — On a double DishDrawer the working drawer is a control experiment: it shares the supply and the drain but not the pump pod or the lid seal, so the difference between them localises the fault immediately.
About 15 min
- Dry the floor and identify the exact phase the water appears — Fill, wash, drain, or with the machine idle.
Tools: towelsAbout 30 min
- STOP before removing the sump, the pump or the inlet valve — Wet components inside a live built-in machine.
The safety boundary
Safety
Water in a built-in enclosure sits directly beside the machine junction box. Switch the dishwasher off at its breaker and close the supply valve under the sink before investigating a leak, and unplug it before removing any panel — a capacitor can hold a charge after the power is off. Do not run the machine to reproduce a leak once you know water is reaching the enclosure floor.
When this becomes a service call
Call a technician when the leak is internal, when it appears at the kick plate rather than the door, or when a door seal still leaks after it has been checked and reseated. Call urgently if the cabinet base or the floor is already soft, because at that point the damage is running ahead of the repair.
