On KDTM354DSS and similar top-control models, the Lock button is on the hidden top-panel control strip. On front-control models like KDFM404KPS, the Lock function may be a secondary function of another button — consult the control panel label. The lock icon on the display should disappear when deactivated.</p> <h3>KitchenAid dishwasher beeps but won't start — what does it mean?</h3> <p>Beeping without starting typically means the door latch sensor is not registering a fully closed door. Push the door firmly until you hear a definitive click. If the door clicks but beeping continues, the door latch microswitch (part WP8269321) has failed and needs replacement. On panel-ready models, check that the custom panel is not preventing the door from fully latching.</p> <h3>Are KitchenAid dishwasher parts the same as Whirlpool?</h3> <p>Yes. KitchenAid is manufactured by Whirlpool Corporation and uses identical internal components. The premium price reflects exterior design, handle style, and finish — not different internal engineering. Whirlpool part numbers cross-reference directly and are typically 15-25% less expensive than KitchenAid-branded equivalents.</p> <p><em>Still having issues with your KitchenAid dishwasher? <a href="/book">Book an EasyBear technician</a> for expert KitchenAid [dishwasher repair](/bay-area/services/dishwasher-repair).
