Questions
about F66.

Can I clear F66 myself?
Remove both lint filters, clean them, rinse them under warm water and dry them thoroughly. If it comes back, it needs a visit.
After cleaning for F66, why must the Miele lint filters be dry before going back in?
Miele warns that wet filters can disrupt drying. Shake them out and dry them carefully before reinstalling.
Should the lint I clean out for F66 go down the drain?
No. Miele asks that the lint go in household waste so microplastics stay out of the waste water.
