What this usually means
On a GE Adora 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.
The symptoms, and the ones that mean something else
- 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.
- Water only at the end of the cycle — The drain hose or the clip at the waste connection.
- 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.
What it usually is, in order of likelihood
- 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 first on a GE Adora dishwasher: the moving parts on this platform are the ones that have been made to a service life rather than for ever.
- 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 second on a GE Adora dishwasher: this is a high-volume platform where the hardware that cycles daily wears out long before anything exotic does.
- 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 third on a GE Adora dishwasher: the door hardware is heavy-duty on this platform, so a seal fault usually means a hinge or a level problem behind it.
The order to work in, and the reason for it
- 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.
- 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.
Owner-side checks, step by step
- Check the machine is level in its opening and firmly fixed to the cabinet — A machine that has dropped at the front leaks at the bottom of the door every cycle.
Tools: spirit levelAbout 20 min
- 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
- 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
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.
When this becomes a service call
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.

This page covers the GE Adora 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.
