The answer first
On a GE Profile dishwasher, most leaks come from the door seal or from too much foam rather than from a failed component. A seal that has hardened, or a gap where the door does not pull up square, lets water out along the bottom edge during the wash. A supply-hose leak is far less common but far more damaging, because it runs under mains pressure whether the machine is on or not. More of this machine is decided by a board and a sensor than by a switch, so a fault that looks mechanical is often a reading the control does not believe.
What you are seeing
- A leak that is there with the machine switched off — The supply side, which is under mains pressure continuously.
- Water along the floor at the bottom of the door — The door seal, the door squareness, or foam.
- A damp cabinet base with no visible puddle — A slow leak that has been running for a while — act on this promptly.
- NEAR MISS: water inside the base and none on the floor — That is a drainage fault and belongs on the page for a dishwasher that will not drain.
Causes ranked for this machine
- Foam from the wrong detergent — Washing-up liquid, or far too much dishwasher detergent, generates foam that climbs the door and finds its way out at the bottom edge. Ranked first on a GE Profile dishwasher: a board decides more here than a switch does, so a sensor the control mistrusts explains more faults than a broken part.
- A hardened, dirty or displaced door seal — The seal round the door is the only thing holding water inside a cabinet that is being sprayed hard, and it hardens and takes a set over years. Ranked second on a GE Profile dishwasher: this tier instruments what older machines simply did, so a fault often turns out to be a reading rather than a broken part.
- A door that no longer pulls up square — A machine that has settled in its opening, or a door with a stretched spring, closes at a slight angle and leaks along one part of the bottom edge. Ranked third on a GE Profile dishwasher: the mechanical parts on this tier are over-specified, which pushes them down the list rather than off it.
What to check first, second and third
- Look through the door for foam standing well above the water — Visible foam means this is a chemistry problem rather than a seal problem.
- Run a finger round the seal feeling for hard, flat or displaced sections — Grease and food residue on the seal also stop it sealing, and both wipe off.
- Look at the gap round the closed door, side to side — A gap that changes across the door means it is not being pulled up square.
The checks you can make yourself
- Run an empty cycle with no detergent to clear the foam, then use the correct dose — Never use hand washing-up liquid in a dishwasher — it foams uncontrollably.
About 45 min
- Clean the seal and its channel, and press any displaced section back into place — A seal that has pulled out of its groove at a corner is a common and free fix.
Tools: clothAbout 20 min
- STOP HERE once the seal, the door, and both hose connections are proven — Reaching the sump means pulling the machine out from under the worktop.
Safety first
Safety
Switch off the breaker before mopping under or behind the machine, and close the supply tap before touching any connection. Water under a built-in machine reaches cabinet bases and flooring first, so act promptly rather than watching it. Be careful in the sump, where broken glass collects invisibly, and never mix dishwasher detergent with bleach or other cleaning products.
Where the owner job ends
Call once the seal is clean and intact, the door closes square, the detergent is correct and both hose connections are dry, and water still appears — that points at the tub, the sump or an internal hose, and reaching any of them means pulling the machine out. Call immediately for any leak that reaches an outlet, and switch off at the breaker first.

What is deliberately not here
This page covers the GE Profile dishwasher as a class, not one family or model line. Part numbers, wiring colours, torque figures and panel fixings differ from build to build and are deliberately not here. Where a family- or model-specific page exists for your unit, that page is the more specific answer and should be read first.
