10 year old Moffat Washing Machine- has been no problem until it started
leaving a 'dirty' ring around the top of the tub. Have also noticed a few
small spots on clothes. It's definitely oil. Is this the transmission ( as
I have read it could be)? Is it worth a repairman's visit or should I go
straight to purchasing new?

Another possibility to look at.
Fabric softener - this repairman says it's made of oil and has to be
used correctly. It's not your machine, but might be relevant.
