Before beginning, make a small, neat "scribe" mark on both the bottom edge of the plastic basket and, right next to it, the top of the metal basket. This match-marks these two pieces. Unscrew and remove the 3 phillips-head screws.
Lift off the plastic handle assembly, exposing the internal pressure system and two springs. Take note of the handle's orientation in relation to the metal piece as it will need to be re-attached in exactly the same position to function correctly.
