The short answer
On the Costway EP washer family a washer that will not drain is usually blocked rather than broken: the pump filter where one is fitted, the drain hose, or a coin trapped in the pump. The brand-generic article leads with the pump because it covers every chassis; on these models the obstructions come first because they are more common and cost nothing to clear.
What you see on the EP 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 EP family
- Drain hose kinked, crushed or badly routed — Ranked first on the EP family — where the machine has been moved recently, this is the change that caused the fault and no part is involved. 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.
- Pump impeller jammed by a foreign object — Second — it explains the humming case completely and the silent case not at all. 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 — Third — 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 pump failed, or the standpipe is blocked — Fourth — and the only group here that is not owner work on these models. 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: Across a roster this wide the shared parts decide the ranking and the cabinet decides the exceptions, so the top of this list is the failure common to every code in the table rather than the brand-wide average.
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: Across a roster this wide the panel layout is shared but the cabinet is not, so the order below is by access on the chassis and the last step is the one that changes with the model code on your plate.
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. Opening a pump filter releases water that is often still hot, so have towels down and a shallow tray ready. Never put a hand into the pump housing while the machine is plugged in, and never reach into a tub that is still moving.

When to call a technician
On the Costway EP washer family the owner line is the filter, the hose and the standpipe. All three are reachable without opening the cabinet. The pump, the pressure switch and the control are not, and a machine that trips its breaker at the drain step should be left off.
