Washing Machine Won’t Drain: Causes, Checks & Fixes

Switch off, unplug and close the water supply before dismantling the appliance

Washing machines combine mains electricity, water, heat and moving parts. Stop using the machine if it leaks, trips the electrics, smells burnt or the drum is loose or grinding.

MOST LIKELY CAUSES

Start with these

Blocked pump filter Coins, lint and small items often stop drainage.

Jammed or failed pump The impeller may be obstructed or the motor may fail.

Kinked drain hose A crushed or badly positioned hose restricts flow.

Blocked household waste The sink spigot or standpipe may be restricted.

◫ Symptom variations Match the exact point in the wash cycle. ⌄

Water remains in drum
Machine stops before spin
Pump hums but no water leaves
Drain error code appears
Water backs up into sink

✓ Quick checks Simple checks before removing panels. ⌄

Note the exact cycle stage when the fault appears.
Record any error code before switching off.
Check external hoses, valves, filter access and visible leaks.
Confirm the machine is level and not overloaded.
Unplug before touching filters, hoses or internal parts.

If the cause is external: correct the hose, valve, load or filter fault and test carefully.

If electrical, motor or internal leaks are suspected: stop and call an appliance engineer.

1 Step 1 — Use the emergency drain procedure Switch off and unplug before opening filters, hoses or panels. ⌄

Process

Switch off, unplug and follow the model instructions to drain residual water safely.

Success looks like: The drum empties enough for inspection.

Escalate when: If water cannot be controlled, stop and call an engineer.

2 Step 2 — Clean the pump filter Switch off and unplug before opening filters, hoses or panels. ⌄

Process

Open the filter access with towels and a tray ready, then remove debris.

Success looks like: Drainage returns.

Escalate when: If the impeller is damaged or seized, the pump needs repair.

3 Step 3 — Inspect the drain hose and waste connection Switch off and unplug before opening filters, hoses or panels. ⌄

Process

Check for kinks, blockages and poor standpipe positioning.

Success looks like: The restriction is found and removed.

Escalate when: A clear hose with no pump action suggests an internal fault.

⌁ Common causes explained Why washing-machine faults develop. ⌄

A washing machine that will not drain usually has a blocked filter, jammed pump, kinked hose, blocked standpipe or a pump or control fault.

The stage of the cycle is the biggest clue. Fill faults happen early, heater faults appear during the wash, pump faults during drain, and motor or balance faults during spin.

⌘ Advanced diagnostics Appliance-engineer checks and repair work. ⌄

Test drain-pump operation.
Inspect pump impeller and wiring.
Check pressure-switch feedback.
Inspect sump hose for blockages.
Verify control-board drain command.

! When to call an appliance engineer Conditions that should end basic troubleshooting. ⌄

The machine trips the electrics.
Water leaks from inside the cabinet.
The drum is loose, grinding or striking the cabinet.
Internal electrical testing is required.
The machine must be dismantled to reach the fault.
The same fault returns after basic checks.

? Frequently asked questions Common washing-machine questions. ⌄

Can I open the door when water is still inside?

No. Drain the machine safely first and use only the documented emergency release.

Why does the machine stop before spinning?

It may be unable to drain, detect an unbalanced load or have a motor or speed-sensor fault.

Should I keep resetting the electrics if the machine trips?

No. Unplug it and arrange electrical fault testing.
