Green Warning Light 512641

1. Removed the top and bottom (philips screws on top and bottom of base, philips screws and torx screws from beneath upper section, small philips screws at top of back face) to access internals.
2. Slid cover plate over front buttons lights outward (sort of unhooks)
3. Clipped wires to green \"OK\" light, removed light from so ... Read more cket (old light was small light inside a cover; replacement had bulb shaped like cover so one piece). Soldered new light to clipped wires, covered with shrink wrap slid on before soldering. Note that there\'s a resistor inline with the new light, and probably under all the shrink wrap on the original. Make sure you don\'t trim that off when shortening the new light\'s leads if doing so. Note! Same as for one other person whose review I read, the replacement light labeled as green was actually orange. Whatever the cause, it\'s next to the OK label and much easier to see! The green was super-dim...
4. Turn machine onto its back and use philips screwdriver to remove espresso brew screen screw and pop screen off (it may stick to the rubber behind a bit).
5. Use flat blade screwdriver to remove the now-visible center fastener.
6. Extract the spring and valve. I was unable to remove the \"valve ring\" easily, and decided that replacing the old valve was probably adequate, and this appears to be true so far. The ring is brass or something, the valve is a plastic or rubber or similar which appears to have hardened over time.
7. Assembly is the reverse of disassembly (haha). But it really is, just using the new spring and valve.
