ok ,, my washing machine is about 8 months old i think , it is a samsung diamond one , i generally love it ! BUT
it keeps filling up with rank smelly water ?
it only has the 1 hose , a cold water one as its a heater thingymabob machine lol
see when i first switch it on the most awful smell of rotten eggs comes up out my sink drain !
any ideas please ? x x

Is the sink ok? Maybe get a plunger and see if anything comes up from the sink. Ther might be some food or something stuck down there x

It sounds like you need to lift the grey pipe up at the back... prop it up so that stale water can not come back through the machine and sit in the pipe x
