I bought a second hand condenser dryer prob 18 months ago
It stopped working and smelt of burning so had an engineer round
Although i empty water and the lint i never knew you had to take the whole condenser unit out and clean as well
I have just occasionally pulled it out and picked of fluff or gave outside a wipe
I had no manual and hadn't had a condenser before only vented
Im sure most people know to take out and clean but for any like me who may of bought second hand please remember to do this part as well
