The short answer
The Artt ATTL washer family covers two listings in the roster below, and on that platform the filter and the impeller behind it are where this fault usually ends. Before anything is blamed, the question is whether the pump is running at all, because a silent pump and a running pump lead in opposite directions. Whether the pump can be heard running is the single most useful observation, and it costs nothing but standing still.
What you observe
- The pump can be heard running but nothing leaves — The motor is turning and the impeller is not moving water, which points at a blockage at the impeller or in the hose rather than at the pump itself.
- No sound at all where the pump should be — Either the pump is not being asked to run or it cannot. A jammed impeller stops the motor dead, and that silence is easy to mistake for a control fault.
- Water appears at the filter cover or under the front — The filter cover has been left loose or its seal has hardened. It is a leak caused by the last attempt to clear a drain rather than by the drain itself.
- NEAR MISS — the drum is empty but the machine still will not spin — With no water to remove, the fault is balance, the lid switch or the motor rather than drainage, and a drainage diagnosis is not what will resolve it.
Causes, most likely first on the ATTL line
- Pump filter blocked with lint, coins or debris — Ranked first on the ATTL line, because it is the first thing the water meets on its way out, it is designed to be opened without tools, and it is the single most common cause of every no-drain call on every make of machine. Nothing in the roster below splits these listings apart for this fault, so the order that follows holds across the whole label.
- Object jammed against the pump impeller — Second on the ATTL line, because a coin or a hair grip that passes the filter lands directly on the impeller and stops it dead, which produces silence where a pump should be running and is frequently mistaken for a dead pump.
- Drain pump failed electrically — Third on the ATTL line: it ranks below the mechanical causes because a genuinely dead pump is far less common than a blocked one, and the two are distinguished by whether anything can be heard at all.
- Pressure sensing telling the machine the drum is already empty — Last on the ATTL line, because the machine never asks the pump to run, so the pump is silent and blameless, which is the one case where silence does not mean a jam.
Check in this order, and why
- Listen for the pump during the drain step — A hum or a whirr with no water moving is a blockage past the pump; complete silence is either a jammed impeller or a pump that is not being asked to run.
- Check the filter cover seal while the filter is out — A hardened seal or a cover cross-threaded on refitting turns a cleared drain into a slow leak, and finding it now saves a second visit to the same panel.
- Turn the impeller by hand with the power off — Behind the filter the impeller should turn freely with a finger. One that will not move is jammed; one that turns loosely with no resistance may have lost its coupling.
- Run a drain or spin programme and watch the whole sequence — With the filter clear and the hose proven, a drain programme shows whether the machine asks the pump to run and whether the water leaves in the time it allows.
Safety first
Safety
Switch off at the wall and let a hot cycle cool before the filter cover is opened: a capacitor can hold a charge after the power is off. Never run the machine with the front panel off to watch the pump. The drum interlock is the only thing that keeps a spinning drum away from hands, and a drain programme can roll into a spin the moment the drum empties..

When this stops being an owner job
Call when the filter is clear, the impeller turns freely and the standpipe takes a bucket of water without backing up, since what is left is the pump itself or the circuit that drives it. A drum full of water can wait a day, but not a week. Drain it through the filter into a tray and take the laundry out, or the smell will outlast the repair.
