As there is soap in the water it won't be the inlet hose.
If it only leaks while drum is filling its probably the soap pipe (goes between soap box and drum), very common fault because there is a lot of movement on that pipe.
If it leaks during the wash its probably the drum/door seal.
If it carries on leaking after a wash then its probably one of the pump hoses, however recently I came across a pressure pipe (goes up to water level sensor) damaged from rubbing.
Too much detergent can also create leaks from excessive foaming, while cheap detergents need a big dose, good quality brand name detergents need surprisingly little.
Depends on the machine how much the parts are (from amazingly cheap to the ridiculous) and some machines have awkward access. Check the price before sanctioning the work, while it seems unnecessary waste, replacement sometimes makes more financial sense.
