Leak and mould smell with Samsung EcoBubble 9kg Washing Machine

Hi there. I wouldn't expect that type of smell. But that bottom plate shows that something has been leaking for several years. If the smell is connected to that bottom plate then with the washing machine disconnected from the mains, you should be able to gently smell right inside the washing machine to see if it is indeed the cause. If that bottom plate does not smell the same as the smell you are getting, then it's got to be totally unconnected.

You should be able to work out where the leak is coming from by just following the trail it's left behind right up until it stops. Bear in mind that water can drip from higher up onto something. But if the leak was coming from a hose between the soap dispenser and the outer tub, then there should be a clear and obvious line of streaks going from the hose and running all the way round the outer tub.

An exception to this would be if the water leak was not coming from where the hose pushes into the drum, but was coming from where it was attached to the soap dispenser, or from a hole in the hose. In such a case, it might be possible for a water leak to drip through the air onto sections below.

But again, this should be able to be traced. If you have, for example, a pump cover that shows water has been running onto it but there is no physical place it could have tracked down to reach that point, then you have to look directly above to see what may have dripped directly onto it.

I have an article here that gives very comprehensive but general advice on how to find a leak on a washing machine
