The short answer
On a Budweiser cooler the usual leak is a blocked drain hole at the base of the rear plate, which puts water in the cabinet floor and then on the ground. Check it first, then the door seal and the drip tray. Condensation on the outside of the glass is not a leak and needs no repair.
What you observe
- Water pooling in the cabinet floor — The drain is blocked and the melt is backing up.
- Ice in the gutter at the base of the rear plate — The melt is refreezing because it cannot get away.
- A trickle out of the door onto the floor — Water that has overrun the interior.
- Water at the back only — A displaced or overfull tray above the compressor.
- NEAR MISS - the outside of the glass running with water — Room humidity on cold glass. Not a leak.
Causes, most likely first on this brand
- A blocked drain hole — First and by a wide margin. The opening is small, a spill or a label closes it, and once blocked the melt has nowhere to go but into the cabinet.
- A door seal admitting humid air — Second. Warm damp air condenses and frosts on the plate, so a marginal drain is asked to carry far more water than the design intended.
- A drip tray displaced or overfull — Third. The tray above the compressor evaporates the melt, and knocked out of place it simply pours onto the floor at the back.
- A cabinet that is not level — Fourth. The gutter and tray both rely on gravity, and a heavy glass door easily rocks a light cabinet off its feet.
- A cracked gutter or split drain tube — Last. Uncommon, and the only cause here that is not an owner fix.
Check in this order, and why
- Find the drain hole at the base of the rear plate — Standing water or a plug of ice around it is the answer.
- Pour a little warm water into the gutter — It should disappear. If it sits, the drain is blocked.
- Test the door seal on a slip of paper — A seal that does not drag is making the water you are mopping.
- Look behind for the tray above the compressor — Displaced or overfull explains water at the back only.
What an owner can safely check
- Clear the drain hole — Flush with warm water and clear the passage gently with a soft flexible probe, never a sharp tool.
Tools: warm water, soft probeAbout 20 min
- Defrost if the gutter is frozen — Switch off and let it melt fully; a frozen drain cannot be cleared while it is ice.
Tools: towelsAbout 120 min
- Clean and test the door seal — Wash the seal and check the paper drag at several points, including the hinge side.
Tools: cloth, paperAbout 20 min
- Level the cabinet and reseat the tray — Level it with the glass door closed, then push the tray home.
Tools: spirit levelAbout 25 min
- STOP HERE if a clear drain and a good seal still leak — That points at the gutter or the tube.
Before you open anything
Safety
Unplug the cabinet before clearing the drain, defrosting or reaching behind it - you are working with water beside an appliance. Never clear a drain hole with a knife, a skewer or stiff wire, because the cooling circuit runs behind that panel and a puncture ends the appliance. Support the glass door while levelling, and mop the floor promptly, since water under a light cabinet reaches the compressor area.
When to call a technician
Call when the drain runs clear, the seal drags on paper, the cabinet is level and the tray is seated, and water still appears inside. That points at a cracked gutter or a split tube. Call sooner if water is reaching the compressor area at the back, or if the appliance trips a breaker or a residual current device, because that becomes an electrical matter.

What this page does not cover
This page covers the Budweiser branded glass-door mini fridges, which have no water supply connection. Plumbed cabinets with ice makers or dispensers leak from lines and valves instead. Not included by design: drain and tray part identifiers, tube dimensions and cabinet specifications, which differ by family.
