The short answer
Leaks on the Costway FP refrigerator family sort themselves by position before anything else: under the crisper drawers, on the floor at the front, or on the floor at the back. Those three point at three different parts, and establishing which one you have takes a towel and one day.
What you see on the FP family
- Water pooling under the crisper drawers — The classic blocked defrost drain: meltwater that cannot reach the tray backs up into the bottom of the cabinet.
- A sheet of ice along the freezer floor — The same blocked drain seen one compartment up, where the water freezes before it can find its way down.
- Water on the floor at the back of the cabinet — The supply fitting, the inlet valve or a drip tray that has slipped its seat and is spilling instead of evaporating.
- Water on the floor at the front, with a dry cabinet — Usually the drain path overflowing forward, or a dispenser line where one is fitted.
Causes, most likely first on the FP family
- Blocked or frozen defrost drain — Ranked first on the FP family — water under the crisper drawers on the Costway FP refrigerator family is this fault and it is reachable from inside the cabinet without tools. Every cycle produces meltwater that runs down a small drain to a tray under the cabinet. Food debris and ice plug that drain, and the water then finds the cabinet floor instead.
- Supply fitting, inlet valve or the dispenser line — Second — it is the cause of most floor water on plumbed cabinets and it is visible once the unit is pulled out. Cabinets plumbed for ice or water carry a connection behind them, and compression fittings weep slowly rather than fail suddenly.
- Drip tray displaced, cracked or overflowing — Third — free to check whenever the cabinet is pulled out, and often found alongside a dusty coil. The shallow tray under the cabinet catches drain water and lets it evaporate on the warm condenser.
- Door seals, humidity and a door left ajar — Fourth — and the one to suspect when the water is beaded on surfaces rather than pooled in one place. Warm room air meeting cold surfaces condenses. A hardened gasket, a door held open by a tall bottle or a very humid room all produce water that looks like a leak but is made inside the cabinet from the air.
- Body: The order below follows the shared parts rather than the differences — the stems in the FP family carry the same running gear and diverge at the cabinet — which is why the top of this list is not where the brand-generic article puts it.
Check in this order, and why
- 1. Dry everything and note where the water comes back — Under the drawers, at the back, or at the front. This single observation removes most of the list.
- 2. Test the door seals with a strip of paper — Close the door on it and pull. Free movement means the gasket is not sealing there, and condensation follows.
- 3. Empty the bottom of the cabinet and find the drain opening — It is a small hole at the back of the compartment floor.
- Body: The stems in the FP family share their layout, so the order below holds across the table; where a stem differs it differs at the cabinet, not at the part you are reaching for.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Never force a stiff wire down a defrost drain — the tubing is soft and a puncture leaks permanently. Close the water supply valve before disturbing any fitting, and mop the floor before working on it.

When to call a technician
On the Costway FP refrigerator family the owner line is the drain opening, the tray, the visible fitting and the door seals. A drain that refreezes within days of being cleared is a defrost problem rather than a blockage, and that one is service work rather than maintenance.
