Short answer
On this platform the first thing to check is not a part: the cabinet is sitting out of level, and water that should be running to a drain is running to the door. What puts it first on this machine: machines this size live in cubbies, knee-holes and corners with very little room around them. The checks below follow that ranking, and the first need no tools.
What you observe
- Water appears at the front of the cabinet and the door swings open rather than easing shut — A door that will not self-close and a wet floor at the front are the same fault seen twice.
- Water under the crisper drawers or along the floor of the fresh-food compartment — It pools at the lowest point inside before it ever reaches the floor.
- Condensation or frost on the liner near one part of the door, with water below it — The wet patch marks where the air is coming in.
Causes, most likely first on this platform
- A cabinet out of level, so water runs the wrong way — Drains, channels and evaporation pans all assume the cabinet stands level or tilts very slightly backwards. Tip it forward and water that would have drained runs to the front and out under the door instead. First, and not narrowly — machines this size live in cubbies, knee-holes and corners with very little room around them.
- A blocked defrost drain — Defrost water is supposed to run from the evaporator down a drain to a pan over the compressor. Block that path with debris or an ice plug and the water still arrives — it just arrives inside the cabinet and then under the door. Second on this platform, and the next thing to check.
- Humid air entering past a door seal — A seal that is not sealing lets room air in continuously. That air is humid, it meets a cold surface immediately, and the water it drops runs down the liner and out under the door without any drain being involved at all. Third here — possible, and behind two checks that are quicker.
Check in this order, and why
- Put a level on the top of the cabinet, front to back and side to side — Two minutes, and it explains a leak that no replacement part would have fixed.
- Find the drain opening at the base of the evaporator area and check it is clear — It tests the top cause directly, and a plugged drain is visible rather than inferred.
- Close the door on a slip of paper at points round the seal and note where it pulls out freely — It maps the failure round the whole door in a couple of minutes and needs nothing but paper.
What an owner can safely check
- Adjust the feet so the cabinet sits level side to side and very slightly back — Done correctly the door eases shut from half open under its own weight.
Tools: spirit level, wrenchAbout 20 min
- STOP at the first step needing a meter on live terminals or a sealed panel off — That is where owner checks end. Write down what came back clean: a technician who knows that spends the visit fixing rather than repeating it.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before reaching into the base, removing a rear panel or pulling the machine out over a wet floor — water and a live compartment is the one combination on this appliance worth taking seriously, and a capacitor can hold a charge after the power is off. If the cabinet is plumbed, close the supply stop valve before touching any fitting. Dry the floor as you go: the second hazard here is the slip, not the shock.
When to call a technician
Call when the water is arriving from behind a sealed panel, from the sealed system, or from a drain that will not clear from the cabinet side. Call sooner if the leak is continuous rather than intermittent — a pressurised supply leak does not wait, and it does not stop when the machine does.

What this page does not cover
This is generalized information for the Preston refrigerator as a class, not for one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer, it is linked among the pages above, and it supersedes this one wherever the two differ. Not covered here: part numbers, drain-line routing, fitting sizes and the disassembly order, all of which differ by family and belong on the page for that family.
