OEM vs Aftermarket 607335 Water Inlet Valve for Bosch/Thermador: Honest Breakdown

Your Bosch SHE4AM12UC dishwasher won't fill, and you've traced it to the water inlet valve. The OEM Bosch part rings up at $127–$189 depending on where you look. The aftermarket version? $49.99. That's a $77–$139 difference for what's essentially the same solenoid valve controlling water flow.

Let's break down whether that price gap matters for this specific part.

Quick Answer

For the 607335 water inlet valve, aftermarket is the smarter move for 90% of repairs. It's the same mechanical function — two solenoids, same thread size, same mounting bracket — at 40% of the OEM cost. OEM only makes sense if you're flipping a high-end home and want original packaging for resale value.

Side-by-Side Comparison

When OEM Makes Sense

There are exactly three scenarios where spending $127+ on the OEM valve is justified:

You're still under warranty. If your Bosch is less than a year old, using aftermarket parts can void remaining coverage. File a claim and let them supply the part.

You're selling the home immediately. Buyers doing pre-sale inspections sometimes flag non-OEM parts in premium appliances. If you're listing a $900K house next month, the $140 difference is noise.

You need original packaging for documentation. Some extended warranty companies require OEM receipts with serial-matched parts. Read your service contract's fine print first.

For everyone else? The OEM premium buys you a Bosch-branded box and... that's about it. The valve inside operates identically.

When Aftermarket Wins

This is a wear part that fails from mineral buildup and solenoid fatigue — usually after 5–8 years. Both OEM and aftermarket versions use the same basic design: dual 120V AC solenoids controlling hot and cold water lines through plastic housings.

The aftermarket version fits models like the SHE4AM12UC, SHE55M15UC, and SHE6AP02UC without modification. Same 3/4" FIP threads, same mounting holes, same wire harness connector. Installation takes 15 minutes and doesn't require special tools.

Here's the key advantage: you're not paying for Bosch's brand markup, dealer network overhead, or premium packaging. You're paying for the part that does the job. The failure rate on quality aftermarket inlet valves is comparable to OEM — both typically last another 6–10 years before the next solenoid gives out.

Speed matters too. When your dishwasher won't fill, you're handwashing for a week waiting on OEM shipping from authorized dealers. Aftermarket ships next-day and gets you back to normal loads by the weekend.

Our Verdict

Save the $140 and go aftermarket unless you're in one of the three narrow OEM scenarios above. This is a straightforward solenoid valve replacement where brand name adds zero functional value. Use the savings toward descaling solution — preventing the next valve failure is worth more than overpaying for this one.

The 607335 aftermarket valve carries the same 1-year warranty, fits the same 50+ Bosch, Thermador, and Kenmore models, and ships faster. That's the repair math that makes sense.

Frequently Asked Questions

Will the aftermarket 607335 valve void my Bosch warranty?

Only if your dishwasher is still under the original manufacturer warranty (typically 1 year). After that, you're legally allowed to use any compatible part under the Magnuson-Moss Warranty Act. Extended warranties vary — check your specific contract terms.

How long do aftermarket inlet valves last compared to OEM?

Functionally identical lifespan — typically 6–10 years depending on water hardness and usage frequency. Both OEM and aftermarket valves fail from the same causes: calcium deposits blocking screens, solenoid coil burnout, and diaphragm wear. Regular descaling extends either version's life more than brand choice.

Can I install the 607335 valve myself or do I need a tech?

DIY-friendly if you're comfortable shutting off water supply and disconnecting wire harnesses. You'll need a wrench, towels for residual water, and 15–20 minutes. The valve mounts behind the lower kickplate with two screws — no specialized tools required. Just match the wire colors when reconnecting.
