Blomberg Washer Not Draining: How to Clean the Drain Pump Filter

If your Blomberg 24-inch front-load washer (WM72200W and similar) finishes with water still in the drum, or drains very slowly, the cause is usually simple. Blomberg’s manual lists three: the door isn’t closed properly, the drain hose is kinked, or the drain pump filter is clogged.

Before you start

• Unplug the washer.
• Let the water cool. Blomberg warns that the water in the drum can be as hot as 70°C (158°F), so wait before opening the filter.
• Put towels down and have a shallow tray ready. There can be a lot of water.

Cleaning the drain pump filter

1. Open the filter cover at the bottom front of the washer.
2. Drain the water into the tray. Some models have a small emergency drain hose next to the filter.
3. Slowly unscrew the filter counter-clockwise and pull it out.
4. Remove lint, coins, buttons, hair ties and anything else caught in it. Rinse it under the tap.
5. Look into the opening and check that the pump impeller turns freely.
6. Screw the filter back in firmly. A loose filter cap can leak, which Blomberg lists as one cause of water under the washer.

Check the hoses

Pull the washer out carefully and make sure the drain hose isn’t kinked or crushed, and that the house drain isn’t blocked. If the washer drains water as soon as it fills, the drain hose may be too low. Connect it as described in the installation instructions.

When it’s a repair

If the filter is clean, the hoses are fine and the washer still won’t drain, the drain pump has probably failed. It’s one of the most common compact washer repairs and usually a one-visit fix. We also repair Blomberg washers that won’t fill, leak, or make loud noise on spin.

How we diagnose a Blomberg washer that won’t drain

When the filter and hoses check out, we work through the drain path in order so you don’t pay for a pump you didn’t need:

1. Drain the tub safely through the filter opening and check what came out. Hair ties, coins and underwire from bras are the usual suspects.
2. Check the hose between the tub and the pump. A sock or a wad of lint can sit in this hose where you can’t see it from the filter opening.
3. Test the pump. We check that the pump gets power during a drain step and that the motor and impeller actually turn.
4. Check wiring and the control if the pump is good but never switches on.

What affects the repair cost

• Blockage or failed part. Clearing a blockage is quicker and cheaper than replacing the drain pump.
• Parts availability. Blomberg is part of the same group as Beko, and many compact washer parts are shared, but some still need to be ordered.
• Installation. A stacked washer-dryer pair or a tight closet takes longer to pull out and reinstall.

How to prevent drain problems

• Empty pockets before every wash. Coins and keys are the most common thing we find in the pump.
• Wash bras, baby socks and small items in a mesh laundry bag.
• Clean the drain pump filter every few months, and more often if you have pets.
• Use HE detergent and don’t overdose. Too much suds slows draining and leaves residue in the filter.

Frequently asked questions

The door is locked and there’s water inside. What should I do?

Don’t force the door. Unplug the washer, let the water cool, and drain it through the filter or the emergency drain hose as described above. Once the water level drops, the door lock normally releases.

Why does my washer smell bad?

Standing water in the filter area and the sump is a common cause of odour. Clean the filter, run an empty hot cycle, and leave the door and detergent drawer open between washes.

Can I keep using the washer until the technician comes?

If it drains slowly but finishes the cycle, you can usually use it carefully. If it stops with water in the drum, stop using it so the pump doesn’t overheat.
