The short answer
On a GE Cafe 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.
What you actually observe
- 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.
The causes, most likely first on this brand
- 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 first on a GE Cafe dishwasher: the doors on this tier are heavy and panel-faced, so hinge sag pulls the seal out of contact long before the gasket itself is worn.
- 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 second on a GE Cafe dishwasher: built-in installation changes the ranking more than the brand does, because access and clearance decide what fails and what merely looks failed.
- A supply hose or inlet valve leaking — The inlet is under mains pressure whenever the tap is open, so a weeping connection there leaks continuously, machine running or not. Ranked third on a GE Cafe dishwasher: supply lines on a built-in run through cabinetry and are the part of the installation nobody can see to check.
Check in this order, and why this order
- 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.
- Look for damp at the hose connections under the sink and at the machine — A leak that is present with the machine switched off is the supply side, and it is urgent.
What an owner can safely check
- 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
- 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
- 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.
Before you open anything
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 to call a technician
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 this page does not cover
This page covers the GE Cafe 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.
