ARTT Washer: Will Not Drain
A washer left standing full of water has nearly always got a blockage rather than a failed pump, and the blockage is usually in the one place designed to be opened by the owner: the drain pump filter behind the lower panel. The ARTT badge appears across several appliance categories, the signature of an importer badge applied to units from more than one source. Clearing the pump filter and checking the hose are owner work and they resolve most of these. Replacing a pump or a pressure switch is not.
What the owner actually observes
- The cycle stops with the drum full of water, often with an error indication.
- The pump can be heard humming or straining at the drain step but the water level does not fall.
- The machine drains very slowly, and the spin never reaches full speed.
- Water drains but comes back into the drum afterwards.
- The machine drains normally on some cycles and not on others.
- Not this fault: If the machine will not begin the cycle at all, the interlocks and supply come first. That is a different fault — see ARTT Washer: Will Not Start or No Power (artt-washer-wont-start).
- Not this fault: If water is escaping onto the floor rather than staying in the drum, that is a different problem. That is a different fault — see ARTT Washer: Water Leak (artt-washer-water-leak).
Ranked for an ARTT washer
- The drain hose — kinked, blocked, or pushed too far into a standpipe — Rank: first — Why ranked here: the hose is behind the machine where it is crushed when the washer is pushed back, and a hose pushed deep into a standpipe siphons or blocks, both of which stop drainage without any part failing
- A blocked drain pump filter — Rank: second — Why ranked here: it ranks where it does because the filter exists precisely to catch coins, buttons, hair and fibre before they reach the pump, because it is the one internal part the manufacturer intends the owner to open, and because on a machine that has never had it cleaned it is blocked far more often than not
- The household drain or standpipe blocked — Rank: third — Why ranked here: a washer discharges a large volume quickly, so a partly blocked standpipe backs up and reads as an appliance fault while the machine is working perfectly
- A procedure or part borrowed from another appliance of the same badge — Rank: fourth — Why ranked here: ranked here because a badge that spans several appliance categories is applied to units from different sources, so a genuine fix for one of them can be actively wrong for this one
- An object jammed in the pump impeller — Rank: fifth — Why ranked here: small hard items that pass the filter reach the impeller and stop it turning, which produces the distinctive hum-without-flow that owners describe as the pump trying
- A pressure switch or level sensor with a blocked hose — Rank: sixth — Why ranked here: the machine decides whether it is empty by air pressure in a small tube, and a tube blocked by detergent sludge leaves the machine believing there is still water, or that there is none
- Note: Because this badge spans multiple appliance categories and therefore multiple sources, the order below assumes nothing transfers: no fix, part number or procedure from another ARTT machine is treated as evidence about this one.
Check in this order
- The drain hose along its whole visible run for kinks and crushing, and how far it enters the standpipe — Order: first — Because: it is free, it is outside the machine, and pushing a washer back into place is a common trigger for this exact fault
- The pump filter behind the lower access panel, after laying towels and draining through the small hose beside it — Order: second — Because: it is free, it is designed to be owner-serviceable, and it is the single most likely finding
- Whether the standpipe backs up when the machine discharges, and whether other drains in the house are slow — Order: third — Because: it distinguishes a plumbing problem from an appliance problem before the machine is opened
Owner-safe checks
- Establish what this specific unit is. Read the data plate for the model, the serial and — importantly — the manufacturer or importer line, then work only from what that plate says. Do not carry over a fix from another appliance that happens to wear the same badge. — Step: first — Tools: a torch and a phone camera — Time estimate: a few minutes
- Listen at the drain step. A pump that hums or strains is powered and blocked; a pump that is entirely silent points at the control, the wiring or the pump itself. That single observation splits the fault list in half. — Step: second — Tools: nothing — Time estimate: a few minutes
- Lay towels and open the lower access panel. Drain the machine through the small emergency hose beside the filter into a shallow tray, then unscrew and remove the pump filter and clear everything from it, including the housing behind it. — Step: third — Tools: towels, a shallow tray, a screwdriver — Time estimate: under a quarter of an hour
- With the filter out and the machine unplugged, reach into the housing and turn the impeller by hand. It should turn freely; anything jamming it comes out now. — Step: fourth — Tools: a torch — Time estimate: a few minutes
- Pull the machine forward and check the drain hose for kinks and crushing along its whole run, then check how far it is pushed into the standpipe and that the standpipe itself is not backing up. — Step: fifth — Tools: a torch — Time estimate: under a quarter of an hour
- Record the model, serial and manufacturer line from the data plate, and treat that — not the badge — as the identity of the machine for the whole job, including when you order a part. — Step: sixth — Tools: a phone camera — Time estimate: a few minutes
- Stop condition: Stop before removing the pump itself or disturbing the pressure-switch tubing inside the cabinet; those need the machine opened and partly dismantled.
Safety
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 washer full of water holds a great deal of weight and the water may be hot, and the pump filter sits directly beside mains components. Always unplug the machine before opening the pump filter, and drain through the emergency hose rather than pulling the filter out against a full drum. Expect the water to be hot if the cycle stopped partway through a warm wash.

When to call a technician
The line is anything past the pump filter and the hose. Call if the pump is silent at the drain step, which points at the pump, its wiring or the control. Call if the machine drains and then refills, which suggests a siphon or a pressure-sensing fault. Call if the filter and hose are clear and drainage is still slow. Call if the drum will not empty and the door remains locked, since a locked door on a full drum needs the machine opened.

What this page does not cover
This page is generalized across every family and model sold under the ARTT badge. It does not carry model-specific error-code tables, family-specific service procedures, sealed-system work or parts numbers, and no model-specific page exists beneath it yet — the data plate on your unit is the authority, not this page. For the other faults on this appliance, start from Common ARTT Washer Problems (artt-washer-problems) and pick the symptom that matches.
