The hose on a smart drive comes out at bottom of the outer tub then goes up to the outlet bracket on the back of the machine. There is no way the water could travel uphill that far from just 1 bucket of water. I would suggest turn power off & pull machine forward away from the wall about 1 metre. Put in 1 or 2 buckets of water and then tip the machine back against the wall. If it won't stay up then get someone to hold it against the wall. Get down & look underneath and see if you can pinpoint exactly where the water is dripping from. Tell me exactly in as much detail as possible & I will advise you what to do.
