Machine has a 'running in' period
Tumble dryers have pulleys and wheels inside the machine that make it work. Tumble dryers may be noisier than usual when first switched on. Sometimes when the product is brand new or not been used for a while a 'rumbling' sound may be heard for the first few minutes of operation. This is normal as the wheels self lubricate but if it continues for more than 5 minutes please ring us for further advice.
Always disconnect your appliance from the mains before you start examining it!
