How to Replace 607335 Water Inlet Valve on Bosch Dishwashers — Step-by-Step

Your Bosch dishwasher starts its cycle, but no water enters the tub. You hear the motor running, but ten minutes later the dishes are still bone dry. The water inlet valve — part 607335 — is the culprit in about 80% of these no-fill situations. It's the electronic gatekeeper that opens when your dishwasher signals it needs water, and when it fails, your machine can't do its job.

This valve replacement works for dozens of Bosch, Thermador, and Kenmore Elite dishwasher models, including the SHE4AM12UC, SHE6AP02UC, and SHE55M12UC series. If you've got basic hand tools and can follow step-by-step instructions, you'll save yourself a $200+ service call.

What You Need Before Starting

• Phillips head screwdriver
• 1/4" nut driver or socket
• Adjustable pliers
• Towels for water cleanup
• Shallow pan or bucket
• Flashlight

Estimated Time: 30-45 minutes
Difficulty: Moderate — You'll need to access the lower front panel and work in tight quarters

Safety First

Turn off the power to your dishwasher at the circuit breaker — not just the control panel. Locate the water shutoff valve under your sink (usually a brass quarter-turn valve) and turn it clockwise until it stops. Even with the water off, expect some residual water in the lines when you disconnect the valve. Keep those towels handy.

Step 1: Access the Lower Front Panel

Open your dishwasher door completely. You'll see two screws at the top corners of the lower access panel (the metal or plastic panel at the very bottom, below the door). Remove these screws with your Phillips screwdriver. The panel should pull forward and down. If it feels stuck, check for hidden clips on the sides.

Step 2: Locate and Disconnect the Water Supply Line

The water inlet valve sits on the left side of the machine, usually mounted to the frame with two screws. You'll see a braided stainless supply line connected to the bottom. Place your pan underneath, then use your adjustable pliers to disconnect this line — turn counterclockwise. Water will drip out, so don't skip the pan. Next, disconnect the electrical connector by pressing the locking tab and pulling straight out.

Step 3: Remove the Internal Water Hose

The valve has an outlet hose that runs from the valve to the sump assembly. This hose is typically held with a spring clamp or screw clamp. If it's a spring clamp, squeeze it with pliers and slide it back on the hose. If it's a screw clamp, use your nut driver to loosen it. Pull the hose off — more water will come out here, so reposition your pan.

Step 4: Remove Mounting Screws and Extract Old Valve

Two screws secure the valve bracket to the dishwasher frame. Remove these with your nut driver or socket. The old valve should now be free. Before you pull it out completely, take a photo with your phone showing how everything connects — it's your installation roadmap.

Step 5: Install the New 607335 Valve

Position the new valve in the same orientation as the old one. The inlet port (threaded fitting) should point down and toward the front. Secure it with the two mounting screws — snug but not overtightened. Reconnect the internal hose and secure the clamp. Push the electrical connector back on until you hear it click. Finally, thread the supply line back onto the inlet port and tighten by hand, then give it a quarter turn with pliers.

Testing After Installation

Turn your water supply back on and check for leaks at both connections. Turn the power back on at the breaker. Start a rinse cycle and watch the valve area carefully for the first few minutes. You should hear the valve open with a distinct click, followed by water rushing into the tub. If you see any drips, shut everything down and tighten the connections a bit more.

Frequently Asked Questions

How do I know if my inlet valve is bad or if it's an electrical problem?

Use a multimeter to test the valve's solenoid coils. With power off, disconnect the electrical connector and set your meter to ohms. Each terminal should read between 500-1500 ohms to ground. If you get infinity (open circuit), the valve's coil is burned out. If you get close to zero, it's shorted. Either way, you need a new valve. If the readings are good but you still have no fill, check the wiring harness and control board.

Can I just clean the inlet valve screen instead of replacing it?

You can try, but it rarely works long-term. The valve itself contains solenoids and rubber diaphragms that wear out over time. Even if you clean sediment from the inlet screen, those internal components are still at the end of their service life. For $50 and 45 minutes of work, replacement gives you a permanent fix instead of a temporary band-aid.

Will this valve work on Thermador dishwashers too?

Yes — Thermador dishwashers built on the Bosch platform use the exact same valve assembly. If your model number starts with DWHD, it's compatible. This is the same valve used across Bosch, Thermador, and Kenmore Elite built-in dishwashers from roughly 2008 to 2018. Always verify your specific model against the compatibility list, but the part numbers 00607335 and AP4070550 cross-reference perfectly.
