The short answer
Water from a BestHome under-counter refrigerator is defrost meltwater that has left its drain path, and the drain hole at the back of the liner is the usual culprit. Because the water goes into the cabinet base rather than onto a visible floor, check the plinth and the joinery around the appliance as well as the cabinet itself.
What you observe
- Water pooling in the base of the cabinet interior — Meltwater backing up because the drain is blocked.
- A damp or swollen plinth beside the appliance — Water has been reaching the joinery for some time.
- Water running down the interior back wall and stopping — The channel works and the drain beneath it does not.
- NEAR MISS — water with soft food and thick ice — Then the cabinet has a cooling fault and the water is the evidence.
Causes, most likely first on this brand
- A blocked drain hole in the liner — First: the hole is small, it sits at the lowest point of the back wall, and crumbs and label paper stop it. Meltwater then runs forward into the cabinet base.
- A displaced tray or drain hose behind the plinth — Second, and common on a built-under unit because both are reached only from the front and both get knocked as the appliance is pushed home.
- An appliance that is not level in its opening — Third. The drain relies on gravity, so a cabinet packed level for appearance rather than for drainage sends its meltwater the wrong way.
- A door that is not sealing — Fourth, always contributing: more humid air in means more frost, more meltwater and a drain carrying more than it was designed for.
Check in this order, and why
- Check the plinth and the joinery beside the appliance — Damp there changes how quickly the rest needs dealing with.
- Find and flush the drain hole at the back of the liner — It is the leading cause and it clears in minutes.
- Check the tray and hose behind the grille — Both are commonly displaced during installation.
- Confirm the appliance is level or tilted very slightly back — A forward tilt defeats the drain however clean it is.
What an owner can safely check
- Empty the lower shelf and dry the liner floor — You need a clear view of the back wall and the drain.
Tools: clothAbout 15 min
- Flush the drain with warm water and a soft wire — Work gently; never force a stiff or sharp tool into it.
Tools: warm water, soft wireAbout 20 min
- Check the tray and hose behind the front grille — The hose should discharge over the tray and the tray sit square.
Tools: torchAbout 20 min
- Level the appliance with a slight rearward tilt — Adjust the feet rather than packing the back.
Tools: spirit level, spannerAbout 20 min
- Dry the cabinet base and the plinth — Damp chipboard holds water long after the leak is cured.

Before you open anything
Safety
Unplug the cabinet or switch it off at its breaker before flushing the drain or working behind the grille — a capacitor can hold a charge after the power is off, and you will otherwise handle water beside a live appliance inside joinery. Never push a sharp probe into the drain hole, because tubing runs behind that wall. Dry any water that has reached the cabinet base before it reaches an outlet.
When to call a technician
Call when the drain runs clear, the tray and hose are seated, the appliance is level, the door seals, and water still appears — and call sooner if the plinth or the cabinet base is already damp. Oily fluid rather than clear water means the sealed system, and the appliance should be switched off until it has been inspected.
