The dryer's card reader has detected an issue with the inserted card. This usually means the card is not seated properly or is not being read correctly.
Click steps to track your progress.
Remove the card from the card reader.
Inspect the card for any visible damage or dirt, and clean if necessary.
Reinsert the card properly and fully into the card reader, ensuring it clicks into place.
If the fault persists, try using a different card or contact Miele Technical Service.
