Washing machine not draining? Causes and solutions
Has the wash cycle finished, but is your laundry still swimming in water? Or worse: does the door refuse to open because the drum is still full? A washing machine that won't drain is incredibly frustrating. The good news is that this problem can often be resolved very simply and at no cost.
Can't fix it? Then the technicians at We.repair are ready to help you. Below we will go through the possible causes step by step.
What you can check yourself first (quick fix) 🛠️
Before you call in a professional, we recommend that you rule out these three culprits.
Note:Always unplug the machine from the socket first for safety!
1. A clogged lint filter (The absolute #1 cause)
If the filter is clogged with a stray sock, a hairpin, or a large lump of lint, the water simply cannot flow to the drain pump.
The test & solution: Open the flap at the bottom right of your machine. Tip: Have a large towel ready and use a flat container (or the small emergency hose next to the filter) to let the water drain out safely. Unscrew the filter, clean it thoroughly, check with your finger in the hole if the impeller at the back can turn freely, and screw the filter back in tightly.
2. A kink in the drain hose
Gently slide the washing machine forward a bit. Check that the ribbed, grey drain hose at the back of the machine is not kinked or trapped. Water needs space to drain.
3. The drain in the wall is blocked
Sometimes your washing machine works perfectly, but the blockage is in the pipes of your house!
The test: Remove the drain hose from the washing machine from the drain pipe in the wall. Carefully pour some water directly into the drain pipe with a bucket. Does the water not drain away or overflow? Then you need a plumber (or a bottle of drain cleaner), not a white goods technician. You can also hang the drain hose with the U-bend in a bucket. If your appliance then works smoothly and pumps the water out easily, the cause may also be further down in the drainage system of your home.
When do you need a We.repair technician? 🔧
Have you cleaned the filter, is the hose kink-free, and does the drain in the wall flow perfectly? Then the blockage or defect is unfortunately deeper in the machine.
A faulty drain pump: Do you hear a soft humming sound as the machine tries to pump out, but nothing happens? Then the pump is blocked or the magnetic motor of the pump has burnt out.This is a typical job for our technicians.
Blockage in the internal hoses: Between the wash drum and the drain pump is a thick, black rubber hose (the tub hose). Often, there is an 'eco-ball' inside that saves detergent. If a small item of clothing (like a baby sock) gets stuck in it, it blocks the entire drain.
Faulty level sensor or control module: The machine incorrectly 'thinks' it is already empty and does not instruct the drain pump to start running at all.
Is your machine still full of water? Don't panic. Our We.repair experts have drainage pumps and hoses for most brands standard in their vans and often resolve this within an hour. Book a We.repair technician now
Behind the scenes: How does a drainage pump work? 💡
Did you know that all that water (sometimes 20 to 30 litres) is squeezed out by a tiny plastic fan?
The drainage pump of a washing machine is usually a 'magnet pump'. This means it operates based on a magnetic field that makes a small plastic paddle spin. The advantage? They are very reliable. The downside? Because they work on magnetism, they have relatively little 'starting power'. Even one small toothpick or a euro coin that happens to be resting against the paddle is enough to stop the entire pump. It may hum (it tries to turn), but it doesn't pump.
What does the error code on your display mean? (By brand) ⚠️
Een wasmachine merkt zelf heel snel dat het water niet daalt. Zodra de maximale afpomptijd is overschreden, stopt het programma en verschijnt er een foutcode:
Note: Error codes may vary by model and year. Always consult the manual for your specific washing machine for certainty. This overview is a guide to the most common codes.
These brands belong to the same group and often share the same error code structure.
E20 / E21 / C2: These are the most common codes and indicate a problem with the water drainage. The machine cannot pump the water away.
EF0 / EFO: This code often indicates a blockage in the filter or the drainage hose, or an activated water protection (aquastop).
Bosch & Siemens
Bosch and Siemens (part of the BSH group) also use a similar system.
E18/ F18: The most common code for a drainage problem. This means that the pumping time has been exceeded, usually due to a blocked pump or a kink in the drainage hose.
E06/ E36 / F03: These codes can also indicate a faulty drainage pump or a problem with the level control.
Samsung
5E/ SE: (The '5' looks like an 'S'). This is the standard error code for Samsung for "Drain Error". Sometimes it also shows Nd for "No Drain". The machine detects that the water is not being drained (quickly enough).
E2: An older code that can also indicate a drainage problem.
LG
OE: This code stands for "Outlet Error". The water has not been removed from the drum after a set time. This indicates a blockage in the filter, the hose, or a faulty pump.
Miele
Miele often uses text messages on the display, which makes it easier.
F11: This specific code indicates a fault in the water drainage (water drainage is blocked or the pump is faulty).
"Water drainage" / "Check drainage": A direct message on the display indicating that the pump, filter, or drainage needs to be checked.
Whirlpool & Bauknecht
FP: This code stands for "Failure Pump". This is the most direct indication of a drainage problem.
F03 / F09: Can also indicate a drainage or overflow problem.
Beko
EF1/ EF20: These codes often indicate a problem with the drain pump or a blockage in the system.
EAA: A general code that may indicate a drainage error.
Repair or replace? (Honest advice) 💰
Let's be very clear:a washing machine that doesn't drain almost never needs to be replaced!
A faulty drain pump may sound like a serious and expensive problem, but it is actually one of the cheapest and easiest parts to replace. Even if there is a blockage in an internal hose, a We.repair technician is often only busy with this for about an hour. Unless your machine is older than 10-12 years and shows other faults, a repair here isalwaysthe smartest investment.
Prevention is better than cure: 4 tips to avoid drainage problems 🛡️
Save yourself a faulty pump or a lot of mopping by following these simple rules:
1. Always use laundry bags for small items Baby socks and thongs are notorious. They are so small that they can slip through the gap between the spinning drum and the rubber door seal during washing. They then end up directly in the drain hose and block everything. Always wash small items in a laundry bag.
2. Check your pockets Coins, screws, nails, and hairpins can damage the plastic blades of the drain pump. Empty the pockets before putting the trousers in the wash.
3. Inspect the filter preventively Do not wait until the machine refuses to drain. Open the lint filter (at the bottom of the machine) every 3 to 4 months and rinse it clean under the tap.
4. Keep your drain pipe clean Pour a splash of boiling water with some soda directly into the drain pipe (in the wall) twice a year to dissolve soap residues. Note: only put the drain hose back in once the pipe has been flushed.
Frequently asked questions about drainage problems ❓
Are you stuck with a washing machine full of water and a closed door? We provide clarity on the most frequently asked questions.
As long as there is water in the drum, the door remains electronically locked (to prevent a flood in your laundry area). First, let the water drain manually through the small hose/filter at the bottom. Once the machine is empty, you often hear a 'click' after a minute and can open the door again. Some brands also have an emergency release cord next to the filter.
This usually means that a hard object (such as a button or a coin) is stuck in the pump housing. The impeller of the pump is constantly hitting it. Turn off the machine immediately, let the water drain, and remove the object from the filter before the impeller breaks.
No, as long as you haven't hung the drain hose too high! A washing machine pump can generally pump water up to a maximum of 1 metre high. Is your drain pipe higher than 100cm from the ground? Then the pump will burn out much faster due to the excessive resistance.
- Open the door flap (usually located in the bottom right corner of the appliance).
- Loosen the filter without removing it. Let the water drain away. Be careful, provide a catchment tray (for example, a baking tray).
- Then fully unscrew the filter and remove it completely from the filter cavity.
- Remove lint and other objects from the filter cavity.
- Check if the pump impeller can rotate in the filter cavity.
- Clean the filter you removed under the tap.
- Reinsert the filter into the designated guide. Tighten the filter properly to prevent leaks.
- Close the door flap.
- Refer to the user manual for more information.
- Check if the drain hose is not incorrectly installed, if there are no kinks in the hose, or if the hose is pinched.
- Check the installation of the drain hose, the lift height, and the drain length, see the user manual of your appliance.
- The U-bend should not be too tightly fitted in the drain pipe. Otherwise, air cannot pass through, creating a vacuum that causes the drain pump to work too hard and possibly not pump out all the water from your appliance.
