The short answer
Water on the floor at a refrigerator has three usual sources and only one of them is a broken part. On a compact cabinet the most likely cause is a blocked defrost drain rather than a burst line, and the second is condensation from a door that is not sealing.
What you observe
- Water at the back of the cabinet — Points at the supply line, the fill valve or an overfull drip tray rather than at the drain.
- Ice building on the freezer floor — A drain frozen rather than merely blocked, which is the same fault at a later stage.
- NEAR MISS: beads of water on the outside of the cabinet in humid weather — That is condensation on a cold surface, not a leak, and it goes when the humidity does.
Causes, most likely first on this cabinet
- A door that is not sealing — Warm humid air drawn in over a cold liner condenses, runs down and collects at the bottom of the cabinet. Ranked first on Danby or Danby Designer: a compact cabinet has little of everything - little thermal mass, a shallow condenser, a small drain and almost no clearance - so the first thing to go wrong is nearly always whatever its installation is asking too much of, and where the plate could be read either way this general page has to hold for both lines.
- A blocked defrost drain — Every frost-free cabinet melts frost on a schedule and sends the water down a small drain to a tray. Ranked second: it ranks below the causes above because it costs more effort, not because it is rare.
- An overfull or displaced drip tray — The tray under the cabinet is meant to evaporate what the drain delivers. Ranked third: it sits here because it produces the same complaint as the cause above it and takes longer to confirm.
- A cracked liner or a blocked internal channel — Less common, and the cause that is left when the drain, the door and the supply are all clean. Ranked last: it is last because on an appliance this size the major components outlive everything around them, and replacing one often costs more than the appliance is worth.
Check in this order, and why
- Paper-test the gasket all the way round — Anywhere the paper pulls out without drag is a leak, and the bottom corners are where it usually is.
- Look under the crisper drawers for standing water — Water there and a dry floor behind the cabinet is the drain, and nothing else produces that pattern.
- Pull the toe grille and look at the tray — A tray sitting off its seat, or brim-full, explains water at the front with no water inside the cabinet.
What an owner can safely check
- Test and clean the gasket, and check the cabinet is standing level — Clean the gasket and the frame, check for a shelf holding the door proud, and set the feet so the door falls closed.
Tools: sheet of paper, adjustable wrenchAbout 20 min
- Empty the cabinet, find the drain opening and flush it with warm water — Clear standing water from under the drawers first, then flush the drain until it runs freely into the tray underneath.
Tools: turkey baster or syringe, warm waterAbout 45 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Water and electricity share the floor under a refrigerator. Unplug the cabinet or switch off its breaker before you kneel in a wet area, before you pull the toe grille and before you reach behind the cabinet, and keep it off while your hands are inside: a capacitor can hold a charge after the power is off.
When to call a technician
Call when the water returns after the drain has been flushed, when it is coming from behind the cabinet with the supply fittings dry, or when there is ice building on the freezer floor that returns within days. Call immediately if water is reaching an outlet or a cord, and leave the cabinet unplugged with the supply valve shut until someone has been.

What this page does not cover
This page covers Danby or Danby Designer as a family, not one model line. Where a page exists for the line named on your plate it is linked below and it is the more precise answer. Not here: the drain routing, tray shape and supply fitting sizes for your specific cabinet, which differ by model line.
