Heat pump dryer not drying and no water in tank

[Dean02]

Hi guys, I have an issue where the cycle goes on for hours, the clothes are still damp and no water has been collected in the tank. All filters are clean, have even stripped machine down and cleaned heat exchange and condenser like brand new but still has the same issue. Does anyone know what else the problem could be?

I have the same issue drum gets hot and steamy but no water in the draw. We clean the door filter every dry and the exchange filter every month, it’s as clean as a whistle. With my previous dryer you could take out and wash the heat exchange , hose it through but this one is supposed to self clean. Despite a 5 year warranty Samsung are charging me for the callout as they say it’s working as expected we will see what the engineer says when he get here
