Why Your Washing Machine Won't Drain
A practical UK guide to the most common reasons a washing machine will not empty properly and the safe first checks worth trying.
Understand the usual signs of a drainage fault, what you can safely inspect first, and when a blocked filter, hose, or pump needs professional help.

When a washing machine will not drain, the problem is often somewhere in the drainage path rather than the spin system itself. Many users first notice water left in the drum, a failed spin cycle, or a humming sound as the pump tries to clear a blockage.
Common signs the machine is not draining
- Water is still sitting in the drum at the end of the cycle.
- The machine stops before spin or refuses to start a spin programme.
- You hear the pump humming but the water level does not drop.
- The door stays locked because the appliance still contains water.
The safest first checks are the simple external ones: the accessible filter, the drain hose route, and the waste connection if your machine drains into a standpipe or sink spigot. A blocked filter, crushed hose, or jammed pump can all stop water leaving the machine properly.
Drainage codes to compare by symptom
- Use Beko E18, Hotpoint F05, Hotpoint F11, or Indesit F11 when the washer stops before spin with water left in the drum.
- Use Samsung 5C if the machine is clearly not draining, or Samsung LC if the same drainage issue has also triggered a leak-style warning.
- Use Bosch E18 if you are seeing the same not-draining pattern on Bosch machines.
Safe first checks
- Switch the appliance off and unplug it from the mains before opening any accessible filter or checking hoses.
- Prepare towels, a tray, or the emergency drain hose if your model has one because trapped water can spill out quickly.
- Check the accessible pump filter for coins, lint, buttons, hair grips, or small fabric items.
- Inspect the drain hose and waste connection for kinks, squashing, or obvious blockages before trying another drain cycle.
If the machine will not drain and there is also water on the floor, treat that as more than a simple blocked-drain problem. Leak and overflow pages such as Samsung LC or Samsung LC1 are a better match than repeating spin cycles.
When to stop and call an engineer
- The filter and hose are clear but the machine still will not drain.
- The pump only hums, sounds rough, or appears to leak after refitting the filter.
- The machine keeps stopping with water inside even after one safe drain test.
- Any next step would require opening the cabinet, removing the pump, or working around live electrical parts.

Frequently asked questions
Is a washing machine that will not drain always a pump fault?+
No. A blocked filter, obstructed hose, blocked waste outlet, or trapped debris around the pump can all cause the same behaviour.
Why does a drain fault stop the spin cycle?+
Most washing machines will not spin properly until the water has left the drum, so drainage faults often look like spin faults at first.
Should I force the door open if water is still inside?+
No. Leave the appliance switched off and use only the safe draining method described for your model. Forcing the door can spill a large amount of water.
