Smeg ECF01 Espresso Machine - Cream (needs fixing)

Recently stopped worked after getting clogged with limescale- 3 attempts at the descaling cycle hasn’t cleared it and water escapes through the bottom rather than coming through the water outlet. Steamer works fine on the de-scale cycles but not much water comes out through the main water outlet. Still turns on fine. Had a pre-existing issue whereby the power button gets stuck, but never bothered me as I just turned on/off at the mains. In good cosmetic condition. Any questions let me know.
