The VPB answer in short
An AVG VPB refrigerator makes water every day by design: defrost melt has to run down a drain, through a tube and into a pan where it evaporates. When any part of that path blocks you get water inside the cabinet, under the drawers or across the floor. That path is the first thing to check, and most of it is reachable.
What the owner sees
- A thin trickle down the inside of the back wall — Where VPB models are concerned, defrost melt running where it should be draining, usually because the channel or the tube is blocked.
- Damp along the door edge with a dry floor — Looking at VPB models specifically, a dry floor and a damp frame is normal; treat it as a leak only if it puddles.
- A clean, clear puddle that returns within hours — On a VPB model, if it comes back quickly and is perfectly clean, isolate the water supply before anything else.
- Droplets on the inside of the rear wall — On VPB models, normal on a humid day in a cabinet that is opened often; a problem only when it runs rather than beads.
- Water pooling on the floor of the cabinet, under the crisper — On VPB models in particular, a pool under the bottom drawer, refilling every day or two, is the drain path almost every time.
- NEAR MISS — water AND a warm cabinet — Then the leak is a symptom of a defrost or airflow fault. Read the cooling-failure page for your model line first.
What actually fails on VPB models, in order
- A blocked defrost drain — First and by a wide margin: the drain hole is small, it sits in a cold damp place, and it silts up with food debris and then freezes.
- A leaking ice-maker or dispenser fill line — Mid-list because it is less common than condensate, but it is the one cause that can flood a room, so it is checked early. It keeps that place on the VPB line.
- A drain pan that has overflowed or shifted — It belongs here because it is visible from the front with the plinth off and because seating it is free.
- A perished or disconnected drain tube — Last of the common causes: the tube hardens with age, cracks at the bend, or falls out of the pan when the machine is pushed back. The VPB models in the table below are no exception.
Work through these in order
- Find the highest point the water reaches — In the VPB family, dry everything, put kitchen paper at likely points and come back: the first sheet to wet tells you where to look.
- Isolate the water supply and see if the leak stops — On a VPB model, it splits condensate from a supply fault in an hour with no tools at all.
- Put kitchen paper down and find the highest wet point — Across the VPB line, water runs downhill, so the top of the trail is closest to the source.
- Clear the drain channel at the back of the cabinet — On every VPB model in the table, the channel and the hole at the bottom of it are where defrost melt is supposed to leave.
Before you begin
Safety
Isolate the machine at the plug or the breaker, and close the water supply if one is fitted; a capacitor can stay charged after the power is off. Never clear a drain with wire or a screwdriver — the tubing and the liner puncture easily and a hole in either turns a free fix into a replacement panel. Leave all switches wired as found.

When to call a technician
Hand it over once the drain flows, the pan is right, the machine is level and the seal passes the paper test, and water still appears. At that point you are looking at tubing inside the cabinet wall or at the defrost circuit, neither of which is reachable without a teardown. Switch the machine off at the wall if the leak is fast.
