Re: Hotpoint drier TDL 30P
It can also depend on which type of drum and front duct you have. Early models had a metal front duct and a felt bearing seal. This failed quite often and was replaced with a plastic drum front duct and old style bearing pads.
If you open the door, does the front filter drop into a metal duct/surround or into a grey plastic one.
If it is a metal one then the only real cure is a drum & duct kit. Possibly to expensive to contemplate.
If you give us the serial number we can tell which type you have.
