How to Repair a Leaking DeLonghi EC-155 Espresso Machine

My DeLonghi EC-155 espresso machine started leaking water out the bottom after several years of use. It turned out to be a bad o-ring in the water line inside the machine. It's a very inexpensive and simple repair that has so far held up well after several months of using daily, making perfect espresso's every time! I found the o-ring at a local Marshall's Hardware store that carries tons of small parts. Home Depot did not carry the 3mm x 2mm size o-ring that I needed.

Recently, it stopped making espresso if the coffee was ground fine. Turns out the pump was getting weak, so I replaced the pump and it's working great now! That video tutorial to replace the pump is here:
