Original humidity sensor for Miele tumble dryer Miele 12575141

The carbon brushes in the moisture sensor are the component that decides when the laundry is dry – and when the dryer stops. When they wear out, the dryer simply stops knowing. The laundry comes out damp, the drying process doesn’t end automatically, and sometimes there’s an unusual scraping noise coming from the drum. Replacing the original Miele 12575141 sensor assembly solves both of these problems in one go.

A moment before ordering – safety above all! To ensure a successful repair and maintain the longevity of the device, it is mandatory to use only original parts. Non-original parts may cause damage and affect the integrity of the device. Now click on the “Check Model Compatibility” button at the top of the page and our system will immediately confirm that the part is suitable for you.

The original Miele 12575141 moisture sensor is a complete assembly that includes carbon brushes to detect moisture remaining in the laundry in the dryer drum. It is suitable for solving two main problems: laundry coming out damp at the end of the drying program, and significant noise caused by worn brushes. The part includes a cover, is manufactured by Miele and is intended for installation by a qualified technician.

Why does the laundry come out damp even after fully drying?

When the dryer finishes a cycle and there are still damp clothes – the heating element is usually not to blame. It’s the sensor that determines when the laundry is dry by measuring electrical conductivity in the fabric. Worn carbon brushes stop effectively touching the drum, causing the sensor to report “dry laundry” too soon – and the dryer to stop prematurely. The result: damp clothes coming out of the dryer cycle after cycle.

Replacing the original assembly 12575141 restores the measurement accuracy to the level set by Miele at the factory. A non-original part with different dimensions will cause the same problem to recur within months.

In our technicians’ experience, a worn humidity sensor is the second most common cause of wet laundry – right after a clogged filter. Therefore, before ordering a part, check that the filter is completely clean. In 30% of cases, the problem is solved there.

What is the cause of the unusual noise from the drum?

A scratching or scraping noise that begins gradually and increases over time is a classic sign of worn carbon brushes. The worn-out brushes drag the metal of the tip on the rotating drum. This is damage that develops, and if not replaced in time, can also damage the drum itself.

A fact that only technicians know: Miele dryers are built to last an exceptionally long time, but the carbon brushes are a deliberate wear component – ​​they wear out so that more expensive components can be preserved. When replaced on time, the rest of the mechanism is preserved for years.

🔧 Who replaces the humidity sensor in a Miele dryer?

⚠️ Replacing the sensor assembly 12575141 requires a certified technician only. This is work on an internal electrical component that requires opening the dryer body, disconnecting electrical connections, and precise assembly. Incorrect installation may cause further damage to the device and endanger the user's safety.

To schedule a technician visit – contact the authorized Miele service.

Estimated execution time by a technician: approximately 30 minutes.

💡 Tip from the experts

In our technicians’ experience, customers who replace the moisture sensor in time – before the noise becomes loud – also save on average a drum replacement. Completely worn brushes leave scratches on the drum surface that require much more expensive repairs. The early warning sign is a slight scratching sound at the beginning of the spin that disappears after a few minutes – that’s the brush trying to make contact. Don’t wait for it to get louder.

Another troubleshooting tip: Wipe the sensor rods (the two thin metal strips inside the drum) with a damp cloth every 2-3 months. A layer of scale and cleaning cloth residue reduce measurement accuracy even without abrasion.

❓ Frequently Asked Questions

What is the difference between a worn humidity sensor and a dirty sensor?

A dirty sensor can be cleaned – wipe the metal bars inside the drum with a damp cloth and the problem may be solved. A worn sensor, on the other hand, no longer makes physical contact with the drum properly. The sign: Cleaning doesn’t help, and the clothes continue to come out damp cycle after cycle.

Can the sensor be cleaned instead of replacing it?

Cleaning helps when the problem is only dirt. If the brushes themselves are worn out – cleaning will not change anything. It is worth cleaning first and checking: if the clothes still come out damp or the noise continues, the original assembly 12575141 needs to be replaced.

When are carbon brushes usually replaced?

There is no set time – it depends on how often you use it. In a dryer that runs 5-6 times a week, the carbon brushes will reach their end after an average of 5-8 years of use. The early sign is a slight noise when spinning and the final sign is damp laundry at the end of a full drying cycle.
