Your washing machine is running, everything sounds normal, but suddenly it stops in the middle of the program. An error message flashes. No handyman appointment available, but your laundry is wet in the drum. The good news: The problem can be solved in 5-10 minutes and is even easier to prevent.
Our blog article shows you step by step how you can avoid washing machine and pump problems with a regularly cleaned lint filter and thus avoid expensive defects, energy and, in the best case, the need for a service technician right from the start.
What does that Lint filter in of the washing machine exactly?
The lint filter or, more precisely, the pump filter, also known as a foreign body trap or small parts trap, is located between Washing drum and drain pumpusually hidden behind a flap in the bottom right-hand corner. It catches everything that comes out of the clothes during a wash cycle, such as lint, hair, handkerchief remnants, coins, but also hair bands, buttons, screws or sand from the last day at the beach. Without this component, all these things would reach the drain pump and block it over time. And if the lint filter is blocked, the machine can no longer pump out the lye water.
The consequences range from unpleasant to expensive:
-
The laundry smells musty after washing and is not clean.
-
Lint accumulates on freshly washed clothes.
-
The spin cycle no longer runs completely.
-
The machine cancels the wash cycle with an error message.
-
In the worst case, water may leak out and damage the drain pump or the appliance itself.
Good to know:
Newer washing machines often no longer have a classic mesh screen, but a so-called Separation process.
Small pieces of fluff do not bother their pumps, they are simply flushed through. The filter area only retains larger foreign bodies. Whoever Lint filter and does not find a fine sieve mesh, there is no need to be alarmed:
The principle is the same, the cleaning process is identical.
Where is the lint filter located on my washing machine and how do I open it?
The washing machine's lint filter is fitted in almost all Front loaders at the bottom front, behind a small flap. Depending on the model, it is located on the left or right under the porthole. In top loaders, on the other hand, the lint filter is often located in the plinth area or even inside the machine. On most washing machine models, this flap can simply be opened with a finger, others require a slotted screwdriver. If in doubt, take a look at the operating instructions, which can often be called up digitally by manufacturer and model name, as some manufacturers even supply their own tool for the flap.
Special case of some models: Some newer washing machines have two flaps. The larger one houses the liquid detergent supply, the smaller one the fluff filter.
Important note:
Never use a sharp knife or a screwdriver with too much force. The covers are mainly made of plastic and break quickly

- Gloves if necessary, the water is often dirty and can be hot
Our practical tip:
Before you open the lid and unscrew the sieve, always place an old, thick towel directly under the lid. Even if you put a bowl underneath, you will often miss a sip. The towel saves you having to wipe the floor afterwards and also catches small particles of dirt that run along the flap.

-
Empty the drain hose first: If there is a small drain hose next to the sieve, first remove it from its holder, open the cap and allow the water to drain completely into the bowl.
➤ This considerably reduces the water surge when unscrewing. Those who skip this step often have the bigger problem. - Lint filter unscrew: Slowly turn the sieve counterclockwise. The moment the sieve is no longer tight, water runs out.
-

-
Check sealing ringCheck the black rubber ring that runs around the strainer carefully for cracks, nicks or breaks. This ring ensures that no water escapes to the outside. If it is damaged, the lint filter must be replaced and not just cleaned.
➤ Spare parts are usually available from specialist dealers or online for just a few francs. - Lint filter and tighten: Reinsert the strainer cleanly and turn it clockwise until it is securely in place, and then close the flap.
-

If the Lint filter clogs during a wash cycle and the machine stops, there is still water in the drum.
- Prepare a large tub and proceed slowly.
- Before opening the Lint filter Always use the drain hose (emergency drain hose) to completely drain the residual water. If the machine does not have such a hose, only open the lint filter slowly as the water will come out directly. A full machine can contain up to 8 liters of water and the Water can be hot.
- Then unlock the drum manually. The operating instructions show where the small emergency lever is located (usually next to the Lint filter itself).
- After cleaning, always start a test run before loading a new wash.
How often Washing machine lint filter clean?
The clear answer to this is: it depends on the household. The rule of thumb is to clean the washing machine's lint filter every three to six months. For those who like to set a fixed rhythm: Twice a year to change the time is an easy anchor to remember.

Every six months is sufficient if:
- the machine runs once or twice a week
- mainly normal everyday laundry is washed
- no animals live in the household
Recommended every two to three months if:
- the machine is used frequently and intensively, for example in families with children
- Dogs or cats live in the household, animal hair clogs the sieve much faster
- heavily linting textiles such as towels, blankets or woolen items are washed regularly
- People with long hair live in the household
Clean immediately after the wash cycle if:
- cleaning cloths, gardening clothes or heavily soiled work clothes have been washed
- The machine has been washing with oil stains, as oil causes hair and small items to clump together and can block the pump during the next wash cycle.
- Sand, soil or other coarse particles were in the laundry
The basic rule:
Better to do it once too often than once too little. The cost is low, but the damage caused by a faulty appliance is considerable. Repair costs for a blocked drain pump are between 150 and 400 francs, depending on the model and region.
What happens if you don't clean the fluff filter?

Protracted Cleaning the lint filter doesn't have to be: How to prevent it in the long term with just a few simple steps
If you want to clean the fluff filter as rarely as possible, a few habits can go a long way.
ü Empty your pockets: Before every wash cycle Check all trouser and jacket pockets for coins, handkerchiefs, hair bands and other small items. This alone will prevent a large proportion of possible blockages.
ü Use laundry nets: Underwired bras, clothing with sequins, rhinestones or parts that break off should always be placed in a laundry net. This way, small items stay in the net even if they come loose.
ü Remove animal hair: Remove animal hair before washing with a lint roller or by briefly shaking out the clothes. Otherwise the sieve will become clogged within weeks, especially during the coat change period.
ü Do not load the laundry full: A drum that is too full increases the stress on the fibers and loosens more lint. A 2/3 filling is optimal.

What the Lint filter cannot & what still gets into the wastewater during washing
Many people assume that the fluff filter retains even the smallest particles. This is not true. The statement that the lint filter in washing machines filters out microplastics is unfortunately still a widespread misconception. The meshes or separators are not fine enough for microfibers that are released from synthetic textiles during washing. These particles are smaller than one millimeter and enter the wastewater unfiltered. So if you wash synthetic clothing, you can use a special wash bag to retain a large proportion of the microfibers.
While other approaches are needed to combat microplastics in clothing, such as consciously choosing natural fibers, you can still reduce the amount of care your washing machine needs in everyday life.
At the same time, you can also improve your ecological footprint by switching to plastic-free and enzymatic washing solutions such as our bluu snO₂ white - Oxi White Booster against odors and stubborn stains on white laundry or our environmentally friendly one-for-all bluu wash strips for all temperatures and textiles.
