I have to say that for many years after suffering this in an old Service

some other similar products if used from new regularly can help while other
suggest the rot away the innards!

We put the detergent staright in to the drum and bypass the detergent
tray. I tend to do my own washing and just squirt some washing up liguid
in to the drum, seems to work ok.
