I've a Zanussi machine it's 5 years old and is on most days.
Yesterday I thought I noticed a smell coming from it and today I'm sure. thought it might be the pipes feeding into it so I used Mr Muscle sink unblocker in case it was coming from there but sink not blocked & no smell from it.
Machine is never left unused for any length of time apart from holidays & we haven't been away since May.
Please help as I think I can smell the stink on the clothes coming out of it now.
