Washing machine won't drain: causes, solutions, and spare parts | Electrotodo

When the washing machine finishes the cycle and the drum is still full of water, the first reaction is usually panic. But don't worry: a washing machine that won't drain is one of the most common breakdowns and, in most cases, you can repair it at home without complicated tools.

In this guide, we explain exactly what is failing, how to check it, and how to repair it yourself, with the right spare parts for your model.

Why isn't the washing machine draining? The most common causes

Before touching anything, it's worth understanding the origin of the problem. In 90% of cases, the fault is due to one of these four reasons:

Clogged pump filter — the most common cause. Lint, coins, buttons, or small objects accumulate, blocking the water flow.
Blocked or faulty drain pump — if the filter is clean and the water still isn't draining, the problem is usually with the pump.
Kinked or clogged drain hose — sometimes the problem is as simple as a hose crushed behind the machine or a coin inside the tube.
Foreign object inside the pump — a coin or a paperclip can block the impeller without being caught by the filter.

Let's solve them one by one, in order of probability.

Before you start: essential safety measures

✅ Unplug the washing machine from the electrical outlet.
✅ Turn off the water tap to prevent more water from entering.
✅ Have towels and a shallow container handy — residual water will come out when you open the filter.

Step 1: Clean the pump filter

The filter is the pump's first line of defense. It is designed to retain objects before they reach the impeller, which is why it frequently gets clogged. Cleaning it every 1-2 months is the best way to prevent this malfunction.

How to clean the filter step by step:

Locate the flap on the bottom front of the washing machine (it usually has a small hinged or removable cover).
Place a flat container underneath and a towel around it.
Slowly unscrew the filter counter-clockwise — water will come out, this is normal.
Remove everything you find: lint, coins, hairpins, buttons…
Rinse the filter under the tap and check that the internal cavity is also clean.
Screw it back in tightly and try a spin cycle.

💡 If the washing machine is now draining, problem solved. If not, continue to the next step.

Step 2: Check the drain hose

Before going for the pump, check the hose. It's a quick step that sometimes saves a lot of work.

Carefully pull the washing machine forward and observe the rear hose.
Check that it is not kinked, crushed, or pinched against the wall.
Disconnect it and blow through it to check for any internal obstruction.
Make sure the end going to the drain is not inserted too deep (it can create a siphon effect).

If the hose is deteriorated or cracked, replace it. We have universal and brand-specific hoses:

Step 3: Check the drain pump

If the filter is clean and the hose is in good condition, the problem is almost certainly with the drain pump. This part is responsible for expelling water from the drum and can fail for two reasons: it's blocked by an object or the motor has stopped working.

Signs that the pump is failing:

The washing machine makes noise during draining but doesn't expel water.
No noise is heard during the draining phase.
Water remains accumulated in the drum at the end of the cycle.

How to access the pump:

Unplug the washing machine and remove the bottom or side panel (depending on the model).
Locate the pump — it is usually connected to the filter and the drain hose.
Rotate the impeller with your finger (with the machine unplugged): it should turn freely. If it's blocked, remove the object preventing it.
If the impeller turns well but the pump doesn't work, the motor is faulty and needs to be replaced.

Step 4: Replace the drain pump

Changing the pump is simpler than it seems and can save you between €80 and €200 compared to a technical repair. The process is practically the same for all brands:

Disconnect the electrical connector from the pump.
Loosen the hose clamps and remove them.
Remove the old pump (it is usually held by screws or clips).
Place the new pump in the same position and orientation.
Reconnect hoses, clamps, and the electrical connector.
Run a short cycle test before closing the panel.

⚠️ The most important thing is to choose the pump compatible with your exact model. An incorrect pump may not fit or work correctly. At Electrotodo, we have original and compatible drain pumps for the main brands:

How to prevent it from happening again: preventive maintenance

Once the problem is solved, these habits will prevent it from recurring:

Clean the filter every month or every 30 washes.
Check pockets before putting clothes in — coins, clips, and keys are the main culprits.
Use the correct amount of detergent — excess suds can damage the pump.
Do a maintenance wash at 60-90°C once a month to remove limescale and bacteria.
Check the drain hose once a year for cracks or deformations.
