Fault code 2.1.24/Connection fault

Your smartphone could not be connected to your Miele appliance. The Miele app displays the message Connection fault and the fault code 2.1.24.

The appliance Wi-Fi is taking longer than expected to open.

Wait a few seconds.

Select Try again.

For some unknown reason, the connection cannot be established even though the appliance Wi-Fi is active.

Select Alternative connection.

  • Follow the instructions in the app to manually connect to the domestic appliance’s Wi-Fi.

  • Android: Wait until the Miele appliance Wi-Fi appears in the list. Select the Miele appliance Wi-Fi.

The mobile device is out of the range of the appliance Wi-Fi.

Move your mobile device closer to your domestic appliance.

  • Note: Make sure that you do not hold the mobile device directly against the Miele domestic appliance.

Select Try again.

The appliance Wi-Fi is not activated or is already switched off (appliance in standby).

Select Adjust state in the Miele app.

Return to the start of the networking process.

Activate the appliance Wi-Fi and follow the instructions in the app.

The serial number of the domestic appliance was not recognized.

Select Adjust number.

Type in the serial number manually. You will find the 8 or 9-digit serial number on the data plate after the slash.

The mobile device has already been networked with the domestic appliance.

The mobile device already recognizes the appliance Wi-Fi and password (i.e., the serial number of the domestic appliance) before pairing and has the Wi-Fi saved as a valid network.

For Android:
A list of saved/known Wi-Fi networks appears in the Wi-Fi settings for your mobile device.

Delete all known Wi-Fi networks that begin with “Miele”.

Repeat the log-in process.

For iOS:
On certain Apple devices, there is no list of known/saved Wi-Fi networks in the Wi-Fi settings.

The appliance Wi-Fi of the domestic appliance must be started, then the connection to the Miele appliance Wi-Fi will be visible in the settings under Wi-Fi.

Tap on the “i” following the entry in the list.

Select Forget this network.

App-guided connection process is unsuccessful.

If the steps outlined above do not work, try a different connection option.

Connect your domestic appliance directly to your router via WPS without first accessing the Miele app.

Only open the Miele app once the router and domestic appliance show that you are connected.

You should then be able to see the domestic appliance in the app and select Add to add it.

If you cannot connect without using the Miele app, there may be a problem with your network settings.
