there's a small removable panel at the bottom of the rear of the dryer, take the screws out and rotate the panel up[ and to the right to allow you access the interior. Lie down on the floor and look in under the drum theres 2 big clips secure the vent hose carrier to the exhaust duct, unclip the hose and carrier, fit new hose to carrier and reassemble.( as with all electrical repairs please ensure the appliance is disconnected from the power supply before removing any panels )
