My washing comes out very greased even at a low temperature. The washing machine is a Indesit only a few months old.

Many people use 40 degrees washes almost exclusively these days and the current trend is to use even lower temperatures to save energy ( Do you save as much as you think? Washing at 30 degrees ). Remember that a non-biological powder, doesn't work as well at lower temperatures so washing at low temperatures requires biological detergent for best results. It's also worth noting that bed bugs (or their eggs) are reported to be able to survive washing at lower temperatures and therefore it is recommended that bedding sheets should be washed at 60 degrees ( Related Whitegoodshelp Blog article: Bed bugs don't drown in the washing machine - but at least they get cleaned )

Also, (as mentioned in detail later) a regular 90 degrees maintenance wash is needed.

Washing machines now commonly suffer from a build up of a greasy deposit and bacteria that causes bad smells, rots hoses & door gaskets and blocks the pressure system causing overfilling or spin failure. An even more serious consequence of this problem is that the aluminium based drum spiders can be corroded by this grease and in serious cases can cause one or more arms to break. This is often fatal to the washing machine. Replace the door gasket with this part and wash the inside of the machine at least once a month with a GOOD HE washer cleaner like this one.
