Q) My washing machine has grey sludge and black marks building up and clothes are coming out with grey streaks on them?
A) The sludge is a waste product which has built up from soil and bacteria with the prolonged use of low temperature washes. A service wash should clear the sludge and periodical maintenance washes should keep the appliance clean and clear. If a maintenance wash has not been performed for a while, more than one maintenace wash may be required to clear it. If the sludge persists you may need an engineer to physically clean the applaince for you.
A maintenace wash consists of the hottest program available on your appliance and your regular amount of wash powder, but place the powder directly into an empty drum and not into the drawer.
