I have a TC7103W Zanussi drier that is 16 yrs old and has worked ok until recently when it started dripping water. I could see at the back of the condenser unit that it was fairly gunged up so after watching utube videos I took the back heater and dust channel cover off. The panel was stuck and took some shifting. Some of the seal came away. Looked on e-spares and a new one is £53!! As only about 8 inches of the seal broke off could I use some sealant on it to ensure a good fit on reassembly? The muck under the cover was unbelievable and am still trying to clean it up. Any advice would be welcome.
