Bosch Dishwasher Door Lock Assembly Parts — Models & Compatibility

Your Bosch dishwasher won't start, and you hear clicking at the door but nothing happens. That's usually the door lock assembly failing — it can't verify the door is secure, so the control board refuses to fill. This hub covers the 612148 electrical door lock assembly that fits Bosch WAS-series front-control dishwashers, plus compatible Thermador models.

Is This the Right Part for Your Model?

Check your dishwasher's model number on the label inside the door frame (open the door and look at the top or side edge). You're looking for model numbers starting with WAS20160UC or WAS24460UC, followed by a revision number like /01, /16, or /33. This lock assembly replaces original Bosch part 00611090 and works across multiple production years — the hardware hasn't changed since these models launched.

About This Replacement Part

The 612148 is the complete electrical door lock mechanism — it includes the latch striker, motor-driven lock assembly, and door position switch all in one unit. When it fails, you'll typically see one of two symptoms: the dishwasher won't start at all (most common), or the door won't latch properly even when you hear the lock trying to engage. The lock assembly uses a small motor to slide the latch into position, and over time the plastic gears inside wear down or the micro-switch that confirms "door closed" stops making reliable contact. Bosch engineered this as a single-piece replacement specifically so you don't have to diagnose which internal component failed — you swap the whole assembly and you're done.

Compatible Bosch Dishwasher Models

This door lock fits these Bosch WAS-series models across all production revisions:

• WAS20160UC (revisions /01, /16, /18, /20, /23, /28, /33, /38)
• WAS24460UC (revisions /01, /16, /18, /20, /23, /28)

The part supersedes AP4355295, 1559966, and PS8727513. If your dishwasher came with any of those original part numbers, this 612148 is the current replacement.

Installation Overview

You'll need to remove the inner door panel to access the lock assembly — it mounts on the right side of the door frame with two screws. Disconnect power first, then remove the door panel screws around the perimeter (they're usually Torx T20). The wiring harness uses a plug connector, so no cutting or splicing required. Most people finish this repair in 30-45 minutes once they have the door panel off.

Why This Part Fails

Two main failure modes: mechanical wear on the lock motor gears (you'll hear clicking or grinding), and corrosion on the door position switch contacts from years of steam exposure. Bosch dishwashers run hot wash cycles, and even though the lock assembly sits outside the tub, moisture still finds its way into the door cavity over time. Once the switch contacts corrode, they lose continuity and the control board thinks the door is open even when it's latched. The other issue is simple plastic fatigue — the lock gets cycled thousands of times, and eventually the internal cam or striker plate cracks.

Need Help Identifying Your Model?

If you're not sure whether this lock fits your dishwasher, check the full model number including the revision code (the /XX part). Early WAS models and later revisions all use the same lock assembly, but if your model number doesn't start with WAS20160UC or WAS24460UC, double-check compatibility before ordering. The easiest verification is matching the old part number — if your existing lock is stamped 00611090, this 612148 is a direct replacement.
