The short answer
What this symptom means on a Vesta refrigerator depends on how the refrigerator is built, and on this one the order runs like this. First — A blocked defrost drain. Last, and the only one that is a technician's job from the outset — A cracked drain channel or liner. Start at the top: those checks are free and need nothing opened.
What you actually observe
- A puddle appearing under the front of the cabinet — Usually water that has run forward from inside rather than water from underneath.
- Water standing inside, under the crisper drawers — That is the signature of a drain that is no longer draining.
- Damp on the inside face of the door — Condensation at the seal line rather than a leak.
- NEAR MISS: water only when the ice maker fills — That is a fill-valve and supply story, and it belongs on a different page.
Causes, most likely first on this build
- A blocked defrost drain — Water from every defrost has to leave through one small drain hole at the back of the compartment. Ranked first on a Vesta: a value build gives you the least margin exactly where the load is highest, so the overloaded case is the normal case.
- Meltwater from a manual defrost with nowhere to go — A manual-defrost cabinet releases everything it has collected as soon as it is switched off. Second here, because a light cabinet transmits everything it cannot absorb, which turns an installation problem into what sounds like a mechanical one.
- Warm air condensing at a poor gasket — A gasket that no longer seals lets warm room air meet cold cabinet air at the door. Third, once the two above are clean: it is quick, free and it settles whether anything needs opening.
- A cracked drain channel or liner — The liner is moulded plastic with a drain channel formed into it, and a crack anywhere along that channel releases water inside the wall of the cabinet. Last, and the reason the order above matters: it is the least likely of the four and the only one that is a service call from the first minute.
Check in this order, and why
- Find the drain hole at the back of the compartment and check it is clear — A blocked drain is the commonest cause and the cheapest to clear.
- Work out whether the water appeared during or after a defrost — Timing separates a defrost accident from a real leak.
- Look for water on the inside of the door rather than under the cabinet — Water at the door line is a seal story.
What an owner can safely check
- Give the cabinet a hand's width of clear air at the back and above it, then run it for a day — Compact cabinets are placed rather than installed, and clearance is the check that is skipped every time.
About 25 min
- Dry the floor completely, then work out where the water appears first — Water travels, so the puddle is rarely above the leak.
Tools: paper towelAbout 20 min
- STOP HERE if the water is coming from the sealed system or from inside a wall of the cabinet — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. Leave the door switch wired exactly as it is: it cuts power to the fan for a reason, and defeating it is never part of a diagnosis.
When to call a technician
Call when the owner-side checks above are clean and water is still arriving, or as soon as water appears to be coming from inside a wall of the cabinet. A plumbed fitting that keeps weeping after it has been re-made is also a call, because a slow leak behind an appliance does far more damage than a fast one in the open.
