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. Where these usually stand, the room is the variable that moves most, so start there rather than inside the unit.
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.
