I have just moved house and a washer dryer was left by previous owners. The washing machine works fine but I cannot get the dryer to work at all. The door locked sign lights up when I select a dry programme, but then just switches itself off after a minute. I know you cannot dry as big as load as you can wash and so have tried only putting a few tea towels, but still no joy. There are no clicking sounds or any signs of life at all. Have tried a spin dry programme, and spin completes but then just stops dead instead of beginning to dry and door locked light goes off. I have never owned a dryer before so am at a loss as to what to try - can anyone please help?
