Hi Gordon,
to replace the drive belt you need to access the drum by removing the top, control fascia panel, plastic kickplate at the bottom & then the front panel, you can then replace the belt. (it is an elastic belt so may be very tight & difficuit to stretch over the drum & motor pulley but it will stretch eventually.)
if you need to purchase the belt, this online shop is very reliable.
