My Washing Machine Won’t Drain!
In my day-to-day repair work, a washing machine that won’t drain is one of the most common call-outs I see. In most cases, the cause is simple and fixable at home but there are a few situations where DIY attempts only make things worse.
Before calling a repair engineer, there are a couple of checks worth doing yourself, as long as you’re prepared for a bit of mess.
First things first: expect water
Any time a washing machine won’t drain, assume there is still water inside the drum.
From experience, people underestimate this and end up flooding the kitchen. Have several towels ready and, ideally, a shallow tray or basin before you start.
The most common cause we see: blockages
In well over half of drain-related repairs, the issue is a blockage.
Typical items we regularly find:
- Coins and small metal objects
- Hair grips and screws
- Lint, fluff, pet hair
- Occasionally small socks or fabric fragments
These usually collect in the pump filter, especially on machines used frequently.
Check the pump filter (worth doing first)
On most modern washing machines, the pump filter is located behind a small flap at the front of the appliance.
Before opening it:
- Drain the water using the emergency drain hose if your machine has one
- If you skip this step, water will pour out onto the floor
Once the water is drained:
- Remove the filter
- Clear out any debris
- Check that the pump impeller behind the filter can spin freely
If the impeller is jammed or stiff, the pump may already be damaged.
No emergency drain hose? Here’s what actually works
Older machines often don’t have an emergency hose. In that case, there are two realistic options.
Gravity draining (when possible)
If your machine has an external drain hose:
- Pull it down to floor level
- Place it into a bucket or basin
- Let the water drain naturally
This works well, but not all modern machines allow this due to internal hose routing.
Manual draining (last DIY option)
If gravity draining isn’t possible:
- Pull the machine forward
- Carefully tilt it backwards
- Open the pump filter slowly
This is messy, heavy work and not ideal in tight kitchens.
If the machine is built-in or very heavy, this is usually the point where calling a technician makes sense.
After clearing the blockage
Once everything is drained and reassembled:
- Run a short rinse or drain cycle
- Listen for the pump activating
- Watch to see if water exits normally
If it drains correctly, the issue was almost certainly a blockage.
When it’s probably not DIY anymore
From repair experience, if:
- The filter is clear
- The pump hums but doesn’t move water
- Or the machine drains intermittently
…the drain pump is likely failing.
At this stage, further DIY attempts rarely help and can damage wiring or hoses. A pump replacement is a common and relatively straightforward repair for a professional.
