Description
Original dosing chamber for liquid detergent for Miele W1/W2 washing machine | 11221580
The EFW 100 dosing chamber, part number 11221580, is an original Miele part. It allows the use of liquid detergent in the main compartment, together with a prewash or delayed start. It is therefore suitable for Miele W1 and W2 washing machines, and WT1 combined dryers, from January 2020 onwards.
Want to wash with both prewash and laundry detergent?
Want to wash with prewash or delayed start, and also use liquid detergent? Currently, according to Miele, this combination is not possible without an additional dosing chamber. But the EFW 100 dosing chamber opens up exactly this possibility, even with detergents that do not come from TwinDos. Check compatibility with your model with the button above, then add to cart.
What does the dosing chamber actually do?
The dosing chamber is connected to the main wash compartment, in the detergent drawer. It holds the liquid detergent, so that it can be released at the right stage of the wash cycle. This prevents premature release, which occurs when prewash or delay start is activated.
Without the dosing chamber, the Miele machine does not accept liquid detergent in the main compartment when prewash is active. The only way then is TwinDos, which is only suitable for Miele's own detergents. For example, if you want detergent for wool or sensitive skin, you also need the dosing chamber in a machine with TwinDos.

Looking for SKU 11996102D?
Did you find this chamber under SKU 11996102D? This is the old number for the exact same product, as Miele updated the catalog number to 11221580, without changing the dosing chamber itself. So you can order by either number, and you will receive the same part.

Compatible models
Miele does not publish a specific model list for this compartment, as compatibility is determined by machine generation, not a single model number.
The dosing chamber is suitable for all Miele washing machines of the W1 and W2 generation. It is also suitable for the integrated washer-dryers of the WT1 generation. The condition is that the machine was manufactured from January 2020 onwards, so older models, even from the same series, are not compatible.
To check for exact fit, locate the model sticker (Typenschild) on the door opening or behind the wall of the machine. It contains the date of manufacture and the full E-Nr.
Installation instructions
- Open the machine's detergent drawer.
- Locate the main wash compartment, usually the compartment marked II.
- Insert the dosing chamber into the main wash chamber until it clicks into place.
- Fill liquid detergent directly into the dosing chamber, not into the washing chamber itself.
Tip from the experts
PLROM Service experts recommend rinsing the dosing chamber with lukewarm water once a month. Detergent residue builds up in the dispensing opening over time, so regular rinsing maintains accurate dosing and prevents clogging.
Questions and Answers
Where do you put washing liquid in a Miele machine?
Detergent enters the main wash compartment in the drawer, usually compartment II. But with prewash or delayed start, put the liquid inside the EFW 100 dosing compartment, not directly in the compartment. So it is released at the right time, and not too early.
Can I use liquid detergent with prewash in a Miele machine?
Without an additional dosing chamber, no. Miele states that this combination is not possible in the regular main chamber. With the EFW 100, yes, it is possible, and also with detergents not manufactured by Miele.
Why do you need this dosing chamber if the machine has TwinDos?
Therefore, anyone who wants another detergent, such as wool soap, also needs the EFW 100 dosing chamber in a machine with TwinDos.
TwinDos is only suitable for Miele detergents, such as UltraPhase.
How do I know if my machine is suitable for the dosing chamber?
Check the manufacturing date on the model sticker on the door opening. If the machine is in the W1, W2 or WT1 category, and was manufactured from January 2020 onwards, it is eligible.
