Washing Machine Not Draining? Start Here
Water sitting in the drum after the cycle — the most common washing machine complaint we get. Usually a clogged filter or a tired pump; occasionally something subtler.
The Water Has to Go Somewhere — 4 Places It Gets Stuck
Drainage is a simple path: drum → filter/trap → pump → hose → standpipe. A blockage or failure at any point means standing water. Our diagnosis walks the path in order of likelihood:
- Clogged filter/trap — lint, coins, hairpins, bra wires. The #1 cause, and the cheapest fix (often included in a general service).
- Failed drain pump — motor windings burnt or impeller jammed. Replaced with a genuine pump, quoted upfront.
- Kinked or crushed drain hose — machines pushed back against the wall pinch their own hose. Checked and re-routed free during any visit.
- Blocked drain valve (top load/semi-auto) — detergent sludge seals the valve shut. Serviced or replaced.
The 60-Second Self-Check
Kill the Power
Unplug the machine before anything else — water and electricity share every inch of this fault.
Locate & Check the Filter
Front loader: open the bottom flap, turn the trap slowly, catch the water in a tray. Clear lint and debris.
Check the Hose Path
Pull the machine out gently — is the drain hose kinked, crushed or clogged with lint at the end?
Run a Drain/Spin Cycle
If it drains now, you're done. If not, the pump or valve needs a technician — book a visit.
Drainage faults also block spinning on most platforms — see our not-spinning guide for how the two connect. On twin tubs the same symptom is usually a jammed drain valve — our semi-automatic repair page covers it.
Digging deeper? The two components behind a stubborn blockage are covered in our drain pump replacement guide (the classic faulty drain pump blockage) and the inlet valve guide — part of the comprehensive washing machine repair guide that anchors every topic on this site.
The Drain Path, Stage by Stage
Drainage faults are easier to reason about as a path than a part. Water leaves the drum, passes the filter, crosses the tub-to-pump hose, spins the pump impeller and exits through the outlet hose to your standpipe — and each stage blocks differently. When the tub stands full and the cycle stalls mid-wash, our emergency repair service clears pump blockages the same day.
| Stage | Typical Blockage | Action |
|---|---|---|
| Filter / trap | Lint, coins, hairpins, bra wires | User-cleanable monthly — always the first stop |
| Tub-to-pump hose | Sock, lint wad at the elbow | Technician clears or replaces the hose |
| Pump impeller chamber | Sludge-packed vanes, jammed object | Impeller freed or pump replaced |
| Outlet hose | Kinks, crushed routing behind the machine | Re-routed free during any visit |
| Standpipe / sink drain | Household drain clog backing water up | Plumber's territory — we confirm it first |
Walking the path in order takes minutes and prevents unnecessary pump replacements — it is exactly how our drain pump service decides between clearing and replacing. Persistent blockages from overloading are covered in the maintenance habits guide. On front loaders, the whole path sits behind one trap flap, which makes the clear-out quick.
Frequently Asked Questions
Quick answers about our washing machine service, repair process, warranty and pricing.
Where is the drain filter on my washing machine?
Front loaders: behind a small flap at the bottom-front of the machine. Top load automatics: usually inside the tub near the agitator base or at the back panel. Semi-automatics: a drain knob/valve at the tub bottom. We show every customer their filter location during service.
Can overloading cause drainage failure?
Indirectly, yes — overloaded washes shed far more lint, which packs the filter and pump chamber faster. If your machine drains slowly after big loads, the filter is the first suspect.
My machine drains slowly but completely. Ignore it?
No — slow draining is an early pump warning. Pumps fail in stages: slow drain today, mid-cycle stall within weeks. A pump replacement now avoids a flooded cycle later.
The pump runs but water barely moves — what's happening?
A running pump with slow drainage means the impeller is spinning but starved or slipping: a packed filter, a lint wad at the tub-to-pump hose, or an impeller loose on its shaft. The pump motor is often still good — clearing the drain path restores flow without a new pump. Skipped filter cleaning is the usual root, as our maintenance guide explains.
Where exactly can the drain path block besides the filter?
After the filter, water crosses the tub-to-pump hose, the pump impeller chamber, the outlet hose and finally your standpipe. Bra wires lodge at the hose elbow, sludge sets in the impeller vanes, and a clogged standpipe backs water up into the machine. Our drain pump service traces the whole path during diagnosis.
Can a washing machine drain upward into a sink?
Only within limits — the drain pump can lift roughly a metre, and hoses routed higher make the pump strain and siphon oddly. If your standpipe or sink edge sits above the machine's rated lift, drainage stays sluggish no matter how new the pump is, which is why correct hose height is set during installation.
How do I know if the drain pump motor is actually dead?
Listen at the drain phase: silence suggests no power reaching the pump — wiring, connector or board relay; a hum with no flow suggests a jammed impeller; a whine with slow flow suggests partial blockage. Those three sounds narrow the fault before any panel comes off, and only the first points toward the control side.
Does standing water damage the machine if I wait?
It works against you within days: lint settles into a plug, odour and mould colonise the standing water, and damp air reaches wiring and bearings. A standing tub also breeds the residue that only a proper deep cleaning service fully removes — don't let it sit.
Can the pressure sensor be fooled by undrained water?
Yes — the water-level pressure switch reads trapped water as an incomplete drain and blocks the next cycle stage, so an original drainage fault grows into fill refusal or spin refusal. Clearing the blockage usually clears the false reading too; the sensor itself rarely needs replacing. The spin side of this is covered in our not-spinning guide.
Is drain pump replacement a big job?
On most front loaders it is a same-visit repair — the pump sits behind the bottom trap panel with two clamps and a connector. On some top-load automatics the tub must be tilted or a cabinet panel removed, which is exactly why the quote is model-specific, as our repair cost guide explains.

Faults travel together because their parts overlap — a drainage failure can dress itself up as a spin problem. These related guides, parts and services help you narrow the cause before booking.
Drainage faults follow water's path: filter, hose, pump impeller, then the pressure sensor that says empty. A humming pump with no flow means the pump needs attention; a silent one points back to the control board.
