Is it one with a removable/cleanable filter?
If so maybe check that its not blocked up.
Is it leaking from the machine or the supply pipes?
If the supply pipes, make sure they are on tight and if still leaking try some ptfe tape in the thread, or buy a new set.
Is it leaking from the front door (of the machine)?
If so, the seal might be damaged, possibly replaceable.
Is it leaking from 'within'?
Probably knackered. Does it make strange noises, maybe with the new flooring the machine hasn't been levelled properly when it was put back. Try adjusting the front legs.
