The short answer
Water around a compact KEG machine usually comes from the door seal or from the hose connections, not from the tub. Foam is the other common answer: too much detergent makes suds that escape past a seal that is doing its job perfectly well.
What you observe
- Water at the tap end rather than at the machine — The adaptor or the inlet connection, not the machine itself.
- The drain hose has come out of the sink — It jumps under pressure if it is not secured.
- NEAR MISS — water standing inside the tub — That is a drainage fault and belongs on the drainage page.
Causes, most likely first on a KEG washer
- Door seal or boot damaged or dirty — Id: doorseal — A front-loading door seal holds back a turning tub of water. Grit, a coin lodged in the fold, or a hardened lip all let water past at the bottom of the door. First on a front-loading machine: it is the largest seal on the machine and the one that collects debris.
- Overfilling or too much detergent — Id: overfill — Second: excess suds fill the space above the water and escape at the nearest seal. The machine is not leaking; it is overflowing foam.
- Tap adaptor or inlet hose connection — Id: tapconnect — Third: this joint takes full mains pressure and is made and unmade constantly. It loosens, its washer hardens, and it weeps down the hose to the floor.
- Drain hose out of the sink or unsecured — Id: drainhose — Fourth, and less common: a pumping hose pushes back. Unsecured, it climbs out of the sink and empties a tub of water onto the floor in seconds.
- Tub or pump seal — Id: tubseal — Last, and the reason the order matters: a worn seal puts water under the machine during the wash rather than at a visible joint. It is the least likely cause here and it is not an owner repair.
Check in this order, and why
- Run a finger round the seal fold for grit and coins — Whatever is in the fold is what is holding it open. First because it is the top-ranked cause above and costs nothing.
- Look through the door or lid mid-cycle for foam — Foam rather than water is the whole answer. Second because its cause ranks second above.
- Dry the tap joint, run a fill and watch it — A drip that returns names the joint immediately. Third because its cause ranks third above.
What an owner can safely check
- Dry every joint, lay paper towel, run a short cycle — Where the paper wets first is the answer, and it costs nothing.
Tools: paper towelAbout 30 min
- Move it somewhere cooler for a day and compare — A few degrees of room temperature change what a small unit can hold.
About 30 min
- Re-make the tap connection with a sound washer — Hand-tight plus a nip; a hardened washer is a common and cheap cause.
Tools: clothAbout 15 min
- Secure the drain hose so it cannot climb out — Tie it to the tap or use the clip supplied; a loose hose empties a tub onto the floor.
Tools: cable tieAbout 10 min
- STOP HERE if the water is coming from under the tub — Tub and pump seals mean the machine comes apart: a service call.
Before you open anything
Safety
Water on the floor beside a live machine is a shock risk before it is a repair: unplug the machine before mopping underneath it, and close the tap before touching any fitting. Never leave a portable machine connected and unattended with the tap open — a joint that lets go under pressure empties into the room until someone closes it.
When to call a technician
Call when the connections are dry, the detergent is ruled out and water still appears under the machine — that means a tub or pump seal, which is an internal repair. Call sooner if water reaches a socket or an extension lead, because that is dangerous rather than inconvenient. Tap, line and regulator parts come from draught suppliers; refrigeration parts come from the seller of the cabinet.

What this page does not cover
This page covers KEG washers as a class, not one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer. Not here: hose sizes, seal part numbers and fitting torques. It is draught cabinets built around a keg, a gas bottle and a tap tower rather than around shelves.
