The short answer
Start from a cracked, displaced or overfull drain pan: on a Summit refrigerator that is the likeliest explanation for what you are looking at, and the water supply line or its fitting is the least likely. Most of this you can settle before anyone is called.
What the symptom looks like
- Ice building on the freezer floor under the food — Meltwater freezing where it lands because the drain below it is closed.
- A wet patch only after a hot day or a big shop — Condensation rather than a leak: more humid air in, more water out, and the drain cannot keep pace.
- NEAR MISS: water only appears when the dispenser is used — That is the dispenser line or its fitting, not the defrost system.
What it usually turns out to be, in order
- A cracked, displaced or overfull drain pan — The pan under the unit is meant to evaporate what the drain delivers. Cracked or knocked out of place, it delivers it to the floor. First on Summit because a compact unit is carried in and set down, never really installed, and nobody re-checks it once it is loaded.
- The cabinet tilted so water runs the wrong way — The drain trough only works if the cabinet leans very slightly back. Tilted forward, meltwater runs into the cabinet instead. Next, and relatedly: how the unit sits decides how it behaves, and the install is the part nobody revisits.
- A blocked defrost drain — Every defrost makes meltwater that must reach the pan underneath. Blocked, it backs up into the cabinet and finds the floor. Third, once the two above are clean: water that cannot leave comes back, and it comes back somewhere you did not choose.
- The water supply line or its fitting — The line to the ice maker and dispenser is under pressure the whole time. A weeping compression fitting drips slowly and steadily. Last, and the order is the point: a compact unit is often fed by a temporary or tap-mounted connection rather than a permanent plumbed line.
The order to work in
- Pull the unit out and look at the pan under the compressor — A pan out of its seat is visible in seconds and free to fix.
- Check whether the unit leans very slightly back, as it should — A forward tilt turns a working drain into a non-working one.
- Look for standing water under the crispers and ice on the freezer floor — Those two together name the drain before anything is opened.
What an owner can safely check
- Pull the unit forward and check the drain pan is seated, whole and not overflowing — Look for a crack at the corners. An overfull pan on a cool day is normal, a cracked one never is.
Tools: a torchAbout 20 min
- Check the tilt and adjust the front feet so the cabinet leans very slightly backwards — This also helps the doors swing closed on their own.
Tools: an adjustable spannerAbout 20 min
- Find the drain hole at the base of the freezer rear panel and flush it with warm water — Do not push anything sharp into it. Warm water and patience clear most of these.

- STOP HERE if the next step means a meter on the inlet valve terminals — Testing a valve coil with the machine live is where an owner check ends and a service call begins.

Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Get help before pulling the cabinet out: a loaded unit runs away from you on a hard floor and the supply line behind it tears easily. Never open sealed-system tubing.
When to call a technician
Call when the drain will not clear with warm water, when the pan is cracked, or when water keeps arriving after the supply has been off for a day. Call the same day for water near the power cord or a socket: that is not something to leave running while you work through a list.

What this page does not cover
This page is about the Summit refrigerator as a class, not one family or model line. Where a family-specific page exists for your unit it is linked below and it is the more precise answer. Not here on purpose: drain routing diagrams, valve part numbers and heater specifications, which differ between families.
