Bosch wvh28360gb washer dryer clothes not fully drying

[Skippydoo]

My seven year old washer dryer seems faulty. Normally clothes are very dry after it’s very long wash and dry cycle. It’s a condensing washer dryer. I noticed clothes were still quite damp, dryer than a spin, but still not fully dry.

I just tried a single t shirt in a quick wash and dry cycle and still very damp. 

Does anyone have any suggestions, other than buying a new one? I want to move soon so would sooner buy a new one when settled in new home so a repair would be great!
