Beko drcs68w condenser dryer?

Beko drcs68w condenser dryer doesn't seem to get very hot, thinks the load is dry when it's still wet, thinks that the filter is in constant need of cleaning(3-4x per load, same with the empty water sensor. Have cleaned the sensor inside the load door, but suspect that the PCB is at fault rather than 3 separate sensors? Dryer had been used about 6 times since purchase 12 months ago, but is now required daily. Any pointers/test values much appreciated,

Thanks,

Chris
