Please help washer dryer isn’t drying?

The dryer section shouldn't cause the washing machine drum to fill with water. However, a washer dryer works by trickling small amounts of cold water into a condenser at the back which then runs into the drum. This water causes the steam created during the drying process to condense into water and run into the drum. This water is then periodically pumped out down the drain. If there is a blockage in the condenser chamber it can cause faults on the drying section. Usually it can cause the laundry to come out hot and steamy but it can eventually cause a safety device to trip and stop the heater from working on the dryer. This would then leave the drying cycle just trickle filling with water and pumping it down the drain but it shouldn't have visible water in the drum. The laundry might come out wet the which potentially could be mistaken for washing.

Hi Andy, no the control knob is definitely intact, and there’s no (at least visible) damage. The whole machine is almost new. Also, all the other programs work as they should be, it’s just the dry option that doesn’t.

Thank you
