The hose route decides it
A compact washer in a closet drains through a hose into a standpipe or a sink, and how that hose was routed decides whether it works. Too low and the machine siphons; too high and the pump cannot lift; kinked behind the machine and it does neither. All three are installation questions.
What you are seeing
- Water remains in the drum at the end of the cycle.
- The machine drains and then refills on its own.
- Drainage is slow and the spin stalls.
- Water backs out of the standpipe.
- The machine has never drained properly since it was installed.
- Not this fault: Water on the floor with an empty drum is a leak - read that page.
- Not this fault: A machine that never starts is a start fault.
Most likely causes, in Direct Supply order
- Drain hose too low, so the machine siphons as it fills — Why ranked: First on a closet installation. The tell is a machine that seems to drain constantly, or refills after draining.
- Drain hose pushed too far into the standpipe — Why ranked: Second: it seals the pipe, air cannot escape, and the drain becomes slow or siphons.
- Hose kinked behind the machine in a tight closet — Why ranked: Third. There is very little depth in a closet and the hose is crushed whenever the machine is pushed back.
- Pump filter blocked with lint, coins or hair — Why ranked: Fourth. On a compact machine the filter is small and blocks sooner than on a full-size one.
- Drain pump failed — Why ranked: Last, and identified by a silent drain step with a clear filter and a correctly routed hose.
What to check, in order
- Look at where the drain hose enters the standpipe and how high it rises first. — Because: Height and depth of insertion are the two variables, and both are visible without tools.
- Note whether the machine refills after draining. — Because: Refilling on its own is siphoning, which is a hose height problem rather than a pump fault.
- Ease the machine forward and check the hose for kinks. — Because: Closet installations crush hoses routinely.
- Listen for the pump during the drain step. — Because: A silent pump with a clear filter and a good hose points at the pump.
Checks you can do safely
- Ease the machine forward and inspect the drain hose along its length. — N: 1 — Tools: Second person, torch — Time: moderate
- Check the hose rises before dropping into the standpipe and is not pushed in too far. — N: 2 — Tools: None — Time: quick
- Check the pump filter if the machine has an accessible one, with the machine off. — N: 3 — Tools: Cloth, tray — Time: moderate
- Run a short cycle and listen for the pump at the drain step. — N: 4 — Tools: None — Time: one cycle
- Report a machine that will not drain with a good hose and a clear filter. — N: 5 — Tools: None — Time: quick
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 pump filter holds water - open it with a tray and towels ready, and never with the machine powered. Water on an apartment floor is a fall hazard. Never open a pump filter on a machine full of water. Do not run the machine with the filter cap loose. Dry and mark any wet floor immediately.
When this becomes a service call
The machine will not drain with a clear filter and a correct hose route. The pump is silent during the drain step. Water backs out of the standpipe. There is a burning smell from the pump area.

What this page does not cover
This page covers the in-room compact washers supplied under the Direct Supply name into resident apartments. It does not cover the contract washers in shared laundry rooms, whose drains are shared, and it names no model-specific pump or filter. Where a family- or model-specific page exists it supersedes this one.
