My washing machine is leaking water from the front, what do I do?

First things first, check if the door is properly closed and if the sealing rubber doesn't have detergent residue or lint stuck on it - that causes leaks right from the first cycle. If the rubber is damaged or worn out, fixing it is cheap and simple to replace. If cleaning the rubber doesn't solve it, the problem could be a clogged drain tube (water stays inside the drum and leaks out the door during the spin cycle) or a faulty water inlet valve, but a cracked tub is less common with this type of front leak. Call a technician to open it up and take a better look, because if it's the rubber it's like half an hour of work, but if it's the drain tube or valve it's also cheap.

Leaking from the front usually comes from the door seal itself, but if you've already cleaned the rubber and it's still leaking, it could be the inlet hose that came loose, the internal door pipe that cracked, or even that drainage tube behind the machine clogged up. Try to check whether the water's coming out specifically during the wash cycle or the rinse cycle so you get a better idea of what's going on. If it's only during water intake, it's a hose thing; if it leaks during the whole cycle, then it could be something more serious with the seal or the drum.

The door seal is indeed the most common culprit, but if you've already cleaned it well and it's still leaking, the problem is probably in the inlet hose or the solenoid valve that controls the water flow - these break a lot and cause leaks right at the start of the wash cycle. I had a machine that started dripping water from the front and I thought it was the seal, but after cleaning it thoroughly I realized the water was coming from above, near the door, and it was exactly the valve failing. If that's the case, you'll need to call a technician because it's not a DIY repair, but know that it's not expensive.
