How to Replace 10006917 Door Lock Assembly on Bosch Thermador Gaggenau Dishwashers — Step-by-Step

Your Bosch dishwasher won't start. You press the button, hear nothing, and the cycle indicator just blinks at you. Nine times out of ten, it's the door lock assembly that's failed — the dishwasher thinks the door isn't secured, so it refuses to run. This is exactly what happens when part 10006917 gives out on models like the SGE53X55UC/51, SHE89PW75N/38, or SMI50C16GB/01.

The lock mechanism takes a beating over thousands of cycles. Eventually the latch wears down or the electronic strike stops engaging properly. You'll notice the door feels loose when closed, or you have to push extra hard to get it to catch. Sometimes it closes but the dishwasher still won't start because the sensor isn't registering the lock.

What You Need Before Starting

This repair is straightforward if you've got the right setup:

• Torx T20 screwdriver
• Flathead screwdriver
• Needle-nose pliers
• Towels or drop cloth
• Small container for screws

Estimated Time: 30-45 minutes

Difficulty: Moderate — requires removing the inner door panel

Safety First

Disconnect power at the breaker before starting this repair. Don't just turn off the dishwasher — kill the circuit completely. You'll be working near wiring and control boards. Also shut off the water supply under the sink. Even though you're not touching the water line directly, it's better to work with a fully isolated machine. Put down towels because you might encounter residual water trapped in the door cavity.

Step 1: Remove the Inner Door Panel

Open the dishwasher door fully. You'll see a row of Torx screws along the top and sides of the inner door panel. Remove all these screws and set them aside — count them so you know you got them all. On most Bosch models, there are 8-10 screws total. Once they're out, carefully lift the inner panel up and away. It might be snug, so wiggle it gently. The control panel will still be attached by wires, so let it hang — don't disconnect anything yet.

Step 2: Locate and Disconnect the Old Lock Assembly

The door lock assembly sits on the right side of the door frame, about midway down. You'll see a white or black plastic housing with a wiring harness plugged into it. Press the tab on the connector and pull it straight out. Now look for the mounting screws — usually two Torx screws holding the assembly to the door frame. Remove these screws and the old lock assembly will come free. If it's stuck, there might be a retaining clip you need to pry loose with your flathead screwdriver.

Step 3: Install the New 10006917 Lock Assembly

Position the new lock assembly exactly where the old one sat. The alignment matters here — the strike has to line up with the catch on the door frame. Thread in the mounting screws but don't fully tighten them yet. Plug in the wiring harness until you hear it click. Now close the door gently to test alignment. The latch should engage smoothly without forcing. If it binds, loosen the screws and adjust the position slightly. Once it's aligned, tighten the screws firmly.

Step 4: Reassemble the Inner Door Panel

Lower the inner door panel back into position. Make sure the top edge seats properly into the groove along the door rim. Thread all the Torx screws back in, starting with the corners and working your way around. Don't overtighten — you're threading into plastic, and it'll strip if you force it. Tighten until snug, then stop.

Step 5: Restore Power and Test

Turn the breaker back on and open the water supply. Close the dishwasher door and listen for the lock to engage — you should hear a distinct click. Press start and confirm the cycle begins. The door should feel solid when latched, with no play or looseness. Run a quick rinse cycle to verify everything's working. If the dishwasher still won't start, double-check that the wiring harness is fully seated.

Testing After Installation

Close and open the door several times to confirm the latch engages smoothly each time. Start a wash cycle and let it run for a few minutes. Try opening the door mid-cycle — it should be locked and won't open until you cancel. If you notice any hesitation in the latch or hear unusual clicking sounds, the alignment might need fine-tuning. Loosen the mounting screws and adjust slightly until it operates smoothly.

Frequently Asked Questions

Will this lock assembly work on Thermador and Gaggenau dishwashers too?

Yes, part 10006917 is a direct replacement for Bosch, Thermador, and Gaggenau models. These brands share the same parent company and use identical door lock assemblies across many of their dishwasher lines. Just verify your model number against the compatibility list to be certain.

My dishwasher still won't start after replacing the lock — what else could it be?

If the door closes properly and you hear the lock engage but the cycle won't start, check the door strike on the tub frame. It might be misaligned or damaged. Also inspect the wiring harness for damage — a pinched wire can prevent the control board from detecting the lock. Finally, the control board itself might have failed, though that's less common than the lock assembly wearing out.

How do I know if my door lock assembly is actually bad?

The clearest sign is when the dishwasher won't start and you see a blinking light pattern on the control panel. You might also notice the door feels loose even when latched, or you hear a clicking sound when closing it but the cycle won't begin. On some models, you'll get an error code indicating a door lock fault. If closing the door firmly doesn't start the cycle, the lock assembly has likely failed.
