What this usually means here
On this platform the water usually comes from the door: a seal that has hardened or picked up debris lets spray run down the inside of the door and out at the front. What puts it first on this machine: the cycle is long and the water charge small, so a marginal supply shows rather than being masked. The checks below follow that ranking, and the first need no tools.
What you observe
- Water at the front of the machine, below the door, only during a cycle — Front and cycle-only places the fault at the door.
- Water under the sink or at the side of the machine rather than at its front — Water away from the door points at a connection rather than a seal.
- The leak began after the machine was moved, or after work in the kitchen — A leak that dates from a change in the room is about the installation.
Causes, most likely first on this platform
- A door seal or door gasket that has failed — The door seal takes the full force of the spray on every cycle. A seal that has hardened, torn or picked up debris lets water run down the inside of the door and out onto the floor at the front of the machine. It leads on this platform: the cycle is long and the water charge small, so a marginal supply shows rather than being masked.
- A supply, drain or disposer connection weeping — Under the machine and under the sink sit several connections made once at installation. Any of them can weep, and the water runs along a hose or a cabinet base and appears somewhere else entirely. Second rather than first — it was installed flush and its clearances were set once, by whoever fitted it — and the next thing to check.
- A machine out of level or set too far forward in its cabinet — A dishwasher that leans forward sends its spray against the door instead of down the tub, and one set proud of the cabinet cannot seal at the door. Both are installation faults that produce a leak years after the machine was fitted. Third: real on this platform, and behind two causes that cost less to rule out.
Check in this order, and why
- Run a finger round the whole seal for hard spots, tears and trapped debris — The commonest source and the only one visible without moving anything.
- Dry every connection under the sink, run a cycle and check each one by hand — A dry cloth and a hand tells you more than looking does, because these fittings weep rather than run.
- Put a level on the door edge and check the machine sits square in its opening — Two minutes, and it explains a leak no part would have fixed.
What an owner can safely check
- Clean the seal and its seating channel, then check the door closes evenly against it — A door catch that has been adjusted or has dropped leaves one corner proud, which the seal cannot make up.
Tools: clothAbout 20 min
- STOP at the first step needing a meter on live terminals or a sealed panel off — That is where owner checks end. Write down what came back clean: a technician who knows that spends the visit fixing rather than repeating it.
Before you open anything
Safety
Switch the dishwasher off at its breaker and shut the supply stop valve before reaching into the sump or disconnecting a hose — a capacitor can hold a charge after the power is off. Expect sharp objects in the sump: broken glass and staples end up there. Never disable the door latch to watch a cycle run.
When to call a technician
Call when the water comes from under the machine with the door seal and the connections all dry, and call immediately if it arrives while the machine is idle — an idle leak is on the pressurised supply and it does not stop on its own. The other line is a floor or a cabinet base that has already softened: that is water damage rather than an appliance fault and it needs looking at on its own terms.

What this page does not cover
This is generalized information for the Porter Charles dishwasher as a class, not for one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer, it is linked among the pages above, and it supersedes this one wherever the two differ. Not covered here: part numbers, seal and hose specifications, fitting sizes and the disassembly order, all of which differ by family and belong on the page for that family.
