Abstract

The present disclosure relates to a tumble dryer () with a filter arrangement () located in a tumble dryer process air flow () for removing lint from process air leaving tumble dryer drum. The filter arrangement comprises a first coarse-mesh filter () and a second fine filter (). A first sensor () detects a correct positioning of the first filter in the tumble dryer, and a second sensor () detects a pressure drop over a process air flow path comprising the second filter. A control arrangement () is configured to initiate a disabling operation which disables the fan arrangement (), if the first filter is not correctly positioned in the tumble dryer or if the pressure drop over the second filter exceeds a predetermined threshold value.
