Product review (5 stars): Very Possibly A Fix for Your Error Code E02 F05.
My rating on the part itself is a 3 (as to Whirlpool/Maytag) but 5+ as to this vendor in terms of speed of shipping and price.  The other day my 1 year old Whirlpool Duet Steam Washer started making funny clicking noises and would not lock or run.  Error Code E02 F05, I believe.  I took a gamble and ordered this part.  Opinions differ but this is how I went.  Take off top (3 brass colored screws, 1/4 inch drive), disconnect control panel (2 x 1/4 inch drive screws and 2 Torx (T20?) in the detergent bay.  Then set the control panel on top.  Remove 4 brass colored screws on bottom (1/4 inch drive).  Remove door (4x T20 Torx, I believe).  Remove front panel top screws (3 x 3/8 drive, I believe).  I did NOT take the front panel all of the way off as I didn't want to mess with the snap ring on the boot/seal on the door.  Last item 2x Torx (T20?) on the door lock itself.  Pull switch gently through side panel while second person holds the panel.  Lift the white plastic tab to pull the top electrical connector and similar for the larger lower one.  Change out with new switch.  They are position specific.  (The big one has tab extensions on the connector and little "slits" in the switch itself so you don't reverse it.  The white one on top goes in by gently lifting the top tab up.  Make note of the round plastic thing at the top as this is a manual release for the door if it is ever jammed. (bottom left of the photo of the article in this product listing).  That was it.  I ran a diagnostic and the first one (C00) cleared the door.  Functioning normally.  This part was quoted as $110 including tax at several appliance parts places in FL (including Marcone).  I went ahead and just purchased a spare.  My compliments to the vendor.  I ordered on Friday, 10/7/2016 during Hurricane Matthew and the vendor and USPS had that bad boy here from South Carolina by Sunday.  That said, I am not happy with Whirlpool as this item should not have failed just a year into its life.
