The short answer
Water in or under a Bosch KFI refrigerator is nearly always defrost water that could not reach its drain. On KFI96AXEAA the drain runs from behind the freezer rear panel to a tray by the compressor, and when it ices over or blocks, the water leaves by the next easiest route - under a drawer and then onto the floor.
What you observe on these models
- A pool that reappears within a day of wiping it — Steady production rather than a one-off spill.
- Water under a crisper drawer with nothing spilled — The drain outlet inside the compartment is the first suspect.
- The floor is wet at one corner only — Levelling decides where water leaves the cabinet, which is why the corner is not the source.
- It started after the unit was moved or levelled — A cabinet tilted the wrong way sends drain water somewhere it was never meant to go.
- NEAR MISS - warm cabinet as well as water — Two faults or one bigger one: start on the cooling page for this family.
Causes, most likely first on the KFI family
- Blocked or iced defrost drain — First on the KFI family by a wide margin. Every automatic-defrost cabinet produces water on a schedule, and the drain that removes it is narrow and cold. Debris or ice closes it, the water backs up, and it leaves by whatever route is available.
- Door seals letting warm moist air in — Second, and the reason a drain ices repeatedly: more ingress means more condensation, which means more water than the drain was designed to carry.
- Water supply line, valve or connections — Third, where the model is plumbed. This water appears at the back and it does not follow a defrost schedule.
- Evaporation tray and levelling — Last. A cracked or displaced tray, or a cabinet tilted forward, sends water to the floor that would otherwise evaporate harmlessly.
Check in this order, and why
- First: find where the water is, not where the puddle is — Inside the cabinet, under the bottom drawer, at the front floor, or at the back wall. Those four locations point at different causes on KFI96AXEAA.
- Second: look under the bottom drawer for ice — Take the drawer out. A sheet of ice there is the defrost drain, and it is the finding that ends most of these calls.
- Third: check the seals with a sheet of paper — Close the door on it and pull. Anywhere it slides out freely is a seal that is letting moist air in.
- Fourth: check the cabinet is level and sitting square — A unit tilted forward sends water out of the front. Levelling changes where water goes without touching the drain at all.
Before you open anything
Safety
Unplug the refrigerator or switch off its breaker before removing any interior panel, and before working anywhere water has collected; a capacitor can hold a charge after the power is off. Dry the floor as you go - a wet floor in front of a heavy appliance is the actual hazard in this job. Never use a metal tool on ice near the evaporator.

When to call a technician
The owner side of a leak on KFI96AXEAA is: find where the water is, thaw what you can reach, check the seals, and level the cabinet. If the water returns on schedule after all of that, the drain is blocked where only a technician can reach it. A continuous leak at the back is plumbing, and that is a call rather than a repair to attempt.
