The short answer
A Costway FPI Washer sitting full of water is reporting a blocked drain path rather than a failed machine in most cases. The path runs tub, filter, pump, hose, standpipe — and walking it in that order is also walking it from free to expensive.
What you see on the FPI family
- Water standing in the tub at the end of the cycle — The defining symptom, and the machine will usually refuse to spin until the water is gone.
- The machine hums at the drain step and nothing moves — The pump is being driven and something is stopping it, most often a coin or a scrap of fabric in the impeller.
- It drains very slowly rather than not at all — A partial restriction in the filter, the hose or the standpipe rather than a complete blockage.
- The load comes out soaking because the spin never ran — Most machines refuse to spin with water in the tub, so a drain fault reads as a spin fault.
Causes, most likely first on the FPI family
- Pump impeller jammed by a foreign object — Ranked first on the FPI family — A hum with no flow after the filter is clean is this and very little else on this model. Coins and underwire work past the tub and wedge the impeller. The motor then hums and the impeller does not turn, which is a distinctive and useful sound.
- Pump filter or coin trap blocked — Second — it is the cheapest point in the drain path and often the whole answer. Where a machine has an accessible filter it collects coins, hair clips, buttons and lint until flow drops to nothing. It is designed to be cleaned and it is the thing owners never clean.
- Drain hose kinked, crushed or badly routed — Third — and always worth a look behind the machine before any panel comes off. A hose crushed against the wall when the machine was pushed back, or a hose pushed too far down a standpipe, stops or siphons the drain. It is an install fault that appears months later when nothing has changed inside the machine.
- Drain pump failed, or the standpipe is blocked — Fourth — and the only group here that is not owner work on this model. A pump that has actually failed is silent at the drain step. A blocked standpipe or house drain backs water up and looks identical from the front, which is why it is worth checking the sink and the standpipe too.
- Body: The order below is this family's rather than the brand's: with one build in the FPI family the ranking is not an average diluted by chassis that fail differently, so the cause at the top is the cause that actually leads on FPI1218US-WH.
Check in this order, and why
- 1. Bail or drain the standing water first — Use the drain hose lowered into a bucket, or bail it. Nothing below is checkable through a full tub.
- 2. Pour water down the standpipe with the machine disconnected — If the standpipe itself backs up, the fault is the house drain and the washer is innocent.
- 3. Open the pump filter where one is fitted — It is usually behind a small door at the front lower corner. Have a towel ready because it holds water even after the tub is empty.
- Body: Because the FPI family is one model, the access route below is the access route — there is no second layout to hedge against, which is exactly what the page above this one has to do.
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. A standard US household branch circuit is 15 A or 20 A at 120 V, and a washer stands in the one place where water reaches the floor, so isolate before you kneel down. Drain the tub before tilting or moving the machine — a full tub makes it unstable and far heavier than it looks.

When to call a technician
Call when the filter is clean, the hose is clear and unkinked, the standpipe drains freely and the machine is still silent at the drain step: that puts the fault at the pump or its wiring, behind a panel on this model. Call sooner if water is also reaching the floor, because a leaking pump housing is two faults at once and the leak is the urgent one.
