Understanding the Problem
What the door latch does and why it fails: The door latch assembly secures the dishwasher door during a cycle and contains the door switches that tell the control board the door is closed and safe to run. If the latch is broken or its switches fail the dishwasher may not start, stop mid‑cycle, display door error codes, or leak. Diagnostic and repair steps (step‑by‑step): 1) Safety first: disconnect power at the circuit breaker or unplug the dishwasher. Do not rely on the door switch to prevent power on. Turn off the water supply if you’ll be removing the inner door panel or working on interior components. 2) Confirm the symptom: note exactly what happens — nothing when you press Start, beeping/door code, cycle stopping, door not staying closed, visible damage to latch/strike, or water leaking from door. 3) Visual inspection: open the door and inspect the latch and strike for broken plastic, worn teeth, missing screws, or melted plastic. Check the striker (on the door frame) is aligned and not loose. 4) Functional test (no tools): close the door firmly and try to start a cycle. If the dishwasher starts only when you hold the door closed or push the door inward, the latch or striker is failing to hold the actuator or the door switch is faulty. 5) Electrical test (with multimeter): after killing power, remove the inner door access panel (see step 6). Locate the latch wiring harness and test the microswitches for continuity. Actuate the latch manually while watching the meter: switches should change state (open/closed) when the latch is engaged/disengaged. If a switch doesn’t change, the latch assembly is bad. 6) Accessing the latch: open the door, remove screws along the inner door perimeter securing the inner door panel (keep track of screws and clips). Carefully fold back or remove the inner panel — it often lifts off hinges or unclips. Locate the door latch assembly at the top center/right/left of the door (model dependent). 7) Disconnecting the latch: note or photograph connector locations. Disconnect the wiring harness from the latch microswitches. Remove the latch mounting screws or clips and pull the old latch free. 8) Installing the new latch (OEM part): position the new latch into the door, secure with the screws/clips, reconnect the wiring harness exactly as it was, and reassemble the inner door panel. 9) Test before final reassembly: restore power, close the door, and start a short cycle to confirm the dishwasher recognizes the door closed and operates. If working, kill power again, finish reassembly, and reinstall any trim. 10) Final check: run an empty wash to verify full operation and check for leaks. Replacement notes: use the correct OEM part made for KDFE104DWH2 (verify model on the rating plate inside the door). Some KitchenAid/Whirlpool parts are interchangeable but confirm compatibility before installation. Safety note: always cut power at the breaker and test that the appliance is de‑energized before testing or disconnecting electrical parts. The door has sharp edges; wear gloves and eye protection. If you are not comfortable with electrical testing or door disassembly, hire a qualified appliance technician.

Helpful Repair Tip
With power off, remove the inner door panel and manually actuate the latch while measuring continuity on the microswitches — a switch that doesn’t change state when the latch is engaged is the failed component.
Frequently Asked Questions
How do I know if the door latch or the door switch is the problem?
Start with a visual inspection — cracked plastic or a loose striker often indicates a mechanical latch failure. Next, with power off, remove the inner door panel and test the microswitches with a multimeter while actuating the latch. If the switches don’t change continuity when the latch is moved, the latch assembly (which contains the switches) is bad. If switches test good but the control isn’t seeing them, check the wiring harness and control board connection.
Can I run the dishwasher if the latch is broken or won’t stay closed?
No — you should not run the dishwasher with a broken latch. The door must be securely latched for the safety interlocks to allow operation; running with the door unlatched risks water leakage and the control will typically prevent operation. Temporarily holding the door closed is not recommended as a long‑term fix and can be unsafe.
