Cafetera espress no echa agua porque tiene la entrada a su caldera obstruida

Since the water has barely been coming in over the last few days, I bought another one (which is the same, but I didn't know that was the case, because it's a different brand but has the same components). I used the old one to access the inside of the boiler and confirm that it was limescale blocking the water inlet. I'll show you how to unclog it using a fine drill bit.
