The short answer
Clear the drain channel at the back of the liner. On a shared Alera it blocks with spilled food and drink that nobody wiped up, and the meltwater then runs out onto the floor. A frosted ice box is second, a door held ajar by stored items third, and a failed tray or liner is the least likely of the four.
What you observe
- Water standing at the back of the liner — The drain channel is blocked.
- Sticky residue in and around the channel — Old spills nobody cleaned up.
- Water under the crisper and out onto the floor — It backed up and found the front of the cabinet.
- Heavy frost in the ice box, dripping when it thaws — More defrost water than the channel can take.
- NEAR MISS — a spilled container somebody left inside — Not a leak. Check before diagnosing.
Causes, most likely first on this class
- Drain channel blocked with spilled food and drink — First because a shared cabinet accumulates spills nobody owns, and they end up in the one narrow channel the cabinet depends on. It closes gradually, then leaks all at once.
- Ice box frosted, then thawing in quantity — Second: a manual box nobody defrosts carries a mass of frost, and when it does thaw it produces far more water than the channel was designed to carry.
- Door held ajar by stored items — Third: warm damp room air entering all day condenses inside, and the resulting water joins everything else the channel has to move.
- Evaporation tray or liner failure — Last. Its tell is water arriving with a clear channel, a defrosted box and a door that seals, and it needs a technician to confirm.
Check in this order, and why
- Check for a spilled container before anything else — Free, and it explains a fair share of shared-cabinet reports.
- Look for standing water at the back of the liner — Water inside means the channel, not the plumbing.
- Clear and flush the drain channel — The top cause on a shared cabinet, and an owner job.
- Defrost the ice box and check the door seal — Left until here because both take time to judge.
What an owner can safely check
- Unplug the cabinet and unload the shelves — Tell the room, and move shared food to a cool place.
About 20 min
- Clean the channel and flush the drain with warm water — Soft brush only; never a metal tool or a wire.
Tools: warm water, soft brushAbout 30 min
- Defrost the ice box fully and dry it — Let the frost melt with the cabinet switched off.
Tools: towelsAbout 60 min
- Close the door on a sheet of paper at each corner — It should drag everywhere. A free corner is a gap.
About 15 min
- STOP HERE if water returns with a clear channel — Tray and liner work is a service call.
Before you open anything
Safety
Unplug the cabinet before clearing a drain or reaching behind it; a capacitor can hold a charge after the power is off, and an office socket is often behind a counter where nobody can see what is switched. Water on a hard breakroom floor is a slip hazard and reaches other equipment quickly, so mop and mark it. Never poke a drain with a metal tool. Discard shared food that has been warm.
When to call a technician
Call when the channel runs clear, the ice box has been defrosted, the door seals all round and water still appears — the evaporation tray or the liner is then the answer. In a workplace, weigh that against replacement before booking it. Unplug the cabinet immediately if water has reached its socket or the breaker will not hold.

What this page does not cover
This page is written for the brand and the appliance class, not for one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and you should start there. Deliberately absent: drain and tray dimensions, seal and hinge part identifiers, compartment ratings and fault-code meanings, all of which differ between the compact, mid-size and glass-door families.
