The short answer
On a Blaze refrigerator, in an outdoor cabinet, water inside the compartment is a drain question and water around it is often weather. Clearing a drain and reseating a tray are owner work; a drain that reblocks weekly is a defrost fault.
What you actually see
- A puddle at the back only — Water behind the unit points at the drip tray or the supply connection rather than at the drain.
- Water running down the inside back wall — Streaks on the rear panel are normal during a defrost and abnormal if they reach the shelves.
- A drip that appears only after the compressor stops — Timing the drip against the cycle separates defrost water from supply water.
Causes, ranked for this refrigerator
- Door seal letting humid air in — Most likely — warm room air condenses the moment it touches cold surfaces, and a leaking seal supplies it continuously — the water is condensate, not a leak. A clean result here does not just remove one part; it removes everything that depends on it.
- Frozen drain from a defrost fault — Common — the pattern is a leak that returns days after every clear-out, which is the tell that the drain is not the root cause. It is worth being sure about this one rather than half-sure, since everything after it assumes a verdict.
- Blocked or split drain tube behind the cabinet — Regular — the tube from the trough to the tray can crack with age or be crushed when the cabinet is pushed back, and then it drains onto the floor. This is the entry most often blamed correctly and diagnosed carelessly, so take the extra minute.
What to check, in order
- First — the door seal — Look for frost or beads on the frame at one corner rather than evenly around it.
- Second — the evaporator area for heavy frost — Empty the freezer section and look for a solid frost sheet on the rear panel rather than a light even coating.
Checks an owner can do safely
- Step 1. Clear the defrost drain — Locate the small hole low on the rear wall inside and flush it with warm water from a baster or syringe until it runs freely.
Tools: turkey baster or syringe, warm waterAbout 20 min
- Step 2. Inspect the drain tube — Follow the tube from the cabinet to the tray, looking for a split, a crush point or an end that has slipped off the tray.

- Step 3. Wipe and recheck the supply fittings — Dry every fitting at the back with a paper towel, then check each again after an hour. A weep shows as a fresh damp ring.

Safety
Shut the water off at the valve and pull the plug before you start. A capacitor can hold a charge after the power is off. Dry the floor before you kneel on it, and if water has reached the base of the cabinet or the outlet, stop and have the circuit checked.
When this becomes a service call
One condition decides it. Water that has reached the base of the cabinet or the outlet is an electrical question before it is a plumbing one; stop, isolate the circuit and have it looked at.
