The short answer
Almost all refrigerator water is the cabinet's own condensate that has lost its way to the drain rather than water from a supply line. Where it shows up tells you which: inside the box is a drain fault, at the front is usually stance or seal, and at the back is plumbing. Shut the water off at the supply valve and wait a day. A leak that carries on with the water off is condensate, and that rules out half the list immediately. On a Summit Appliance refrigerator the cause that ranks first is defrost drain blocked or frozen.
What you observe
- A sheet of ice or standing water under the crisper drawers — The signature of a blocked defrost drain.
- Water at the front of the cabinet, on the floor — Either the stance is sending it forward or the door is not sealing.
- NEAR MISS — the cabinet is also failing to hold temperature — Then treat it as a cooling fault first: that page is the more urgent one.
Causes, most likely first on a Summit Appliance refrigerator
- Defrost drain blocked or frozen — Debris silts the small drain hole at the back of the compartment, the tube below it freezes solid, and meltwater backs up inside the cabinet instead of leaving it. It ranks first on a Summit Appliance refrigerator because a built-in installation breathes through a narrow cabinet cut-out, so anything airflow-related surfaces here long before it would on a free-standing machine.
- Cabinet standing out of level — A cabinet tipped forward sends interior water to the front instead of to the drain, and holds the doors slightly open into the bargain. Second on this platform: the stance is free to correct and it makes every other symptom on the list worse.
- Door gasket letting humid air in — Warm room air entering continuously condenses on the cold surfaces inside and runs down the liner, and the drain cannot keep up with it. Last, and the reason to work down the list rather than guess: a cabinet opened constantly gains far more humid air than one opened twice a day.
Check in this order, and why
- Clear the drawers and look at the floor of the fresh-food compartment — Standing water or a sheet of ice there settles it at once.
- Put a level on the top of the cabinet, front to back and side to side — The stance explains both the water path and a door that will not self-close.
- Run a sheet of paper round the closed door and find the slack points — Any point where the paper pulls out freely is admitting humid air.
What an owner can safely check
- Empty the bottom of the cabinet and flush the drain hole with warm water and soft tubing — Never use a wire or anything sharp — it punctures the tube.
Tools: turkey baster or soft tubing, warm water, clothAbout 25 min
- Adjust the front feet until the cabinet sits very slightly high at the front — Doors should then close under their own weight from half open.
Tools: spirit level, spannerAbout 20 min
- Clean the gasket and the frame it lands on, then re-seat any lifted section — A warm, damp cloth restores a gasket that has taken a set.
Tools: cloth, paperAbout 15 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, whatever the ranking above says.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before removing any interior panel, and dry the floor before working beside a powered appliance. Never clear a drain with a wire, and never open a sealed refrigerant line.
When to call a technician
Call when the drain, the stance and the gasket are all clear and water is still appearing, or the moment water is arriving from a plumbed joint you cannot isolate. On a compact machine, expect access to be the larger half of any labour quote — the part itself is rarely the expensive part.

What this page does not cover
This page is written for the Summit Appliance refrigerator as a class, not for one family or model line. Where a family- or model-specific page exists for your unit it is linked above, it is the more specific answer, and it is the one to read first. Deliberately not here: part numbers, wiring colours, panel removal order and torque figures, all of which differ between families under the same nameplate.
