OEM vs Aftermarket Door Lock Assembly for Bosch/Thermador: Honest Comparison (10006917)

Your Bosch dishwasher won't start, and you've traced the problem to the door lock assembly. The OEM Bosch part (00629580) runs $180–$240 depending on where you shop. The aftermarket version? Around $35–$50. That's a massive price gap, but does the cheaper part actually work?

I've installed both versions across SGE53X55UC, SHE89PW75N, and dozens of other Bosch, Thermador, and Gaggenau models. Here's what you actually need to know.

Quick Answer

For most homeowners, the aftermarket door lock assembly (10006917) is the smarter buy. It fits the same models, uses identical mounting points, and costs 75% less than OEM. Unless you're under warranty or repairing a high-end Thermador in a commercial setting, save your money and go aftermarket.

Side-by-Side Comparison

When OEM Makes Sense

There are legitimate reasons to spend the extra $150 on the OEM part:

• Active warranty: If your Bosch or Thermador is still under manufacturer warranty, using aftermarket parts can void coverage. Don't risk it.
• High-end commercial installs: Restaurants or rental properties with premium Gaggenau units may want OEM for consistency and potential liability reasons.
• Installer requirement: Some authorized service companies won't install aftermarket parts due to contractual agreements with Bosch.
• You've had multiple aftermarket failures: If you've tried two aftermarket assemblies and both failed within months, it might be worth paying for the factory part.

But honestly? Those scenarios cover maybe 15% of repairs.

When Aftermarket Wins

The aftermarket door lock assembly (10006917) is a direct replacement that works in all the same Bosch, Thermador, Gaggenau, and Kenmore models. We're talking SGE53X55UC/51, SGE68X55UC/52, SHE89PW75N/38, SMI50C16GB — hundreds of model numbers.

The most common failure mode is simple wear. The door lock assembly sees mechanical stress every single cycle. After 5–8 years, the latch mechanism wears down or the electronic switch inside fails. When this happens, you'll see "door won't close" errors or the dishwasher simply won't start even though the door appears latched.

Here's the thing: the aftermarket part fails the same way, at roughly the same rate, as the OEM version. Both are plastic assemblies with similar electronic microswitches inside. The $150 price difference doesn't buy you a fundamentally better component — it buys you a Bosch logo.

Installation is identical. Disconnect power and water (critical safety step), remove the inner door panel, unscrew the old assembly, disconnect the wire harness, and reverse the process. Same four screws, same connector. The aftermarket part drops right in.

Our Verdict

Unless you're under warranty or have a specific contractual reason to use OEM, go with the aftermarket door lock assembly. You'll save $130–$190 and get the same functional result. We've seen these aftermarket units run 5+ years without issues in SGE and SHE series models. The money you save can cover two future repairs if needed.

Frequently Asked Questions

Will the aftermarket door lock void my Bosch warranty?

Yes, if your dishwasher is still under the original manufacturer warranty. Bosch can deny coverage if they discover non-OEM parts during a warranty claim. Once you're out of warranty, it doesn't matter.

Does the aftermarket part work with Thermador and Gaggenau models?

Absolutely. This door lock assembly (10006917) replaces the same part numbers across Bosch, Thermador, Gaggenau, and Kenmore Elite dishwashers. The brands share components since they're all owned by BSH Home Appliances. Check your model number against the compatibility list to confirm.

How long does it take to replace the door lock assembly?

About 30–45 minutes if you're comfortable with basic appliance repair. You'll need to remove the inner door panel, which involves unscrewing multiple screws around the perimeter. Disconnect power and water first — this is a safety-critical step since you're working with electrical components near potential water exposure.
