10023852 Genuine OEM Bosch Dishwasher Water Valve
The 10023852 is a genuine Bosch OEM warm water inlet valve for Bosch, Thermador, Dacor, and Gaggenau dishwashers. This valve regulates the flow of warm water into the dishwasher during each wash cycle — a solenoid opens when the dishwasher calls for water and closes once the required amount has been reached, which is what prevents overfilling or underfilling and supports thorough cleaning performance.
Rated 110-127V, 60Hz. Common causes of a bad valve range from mineral buildup due to hard water, which can obstruct the valve, to general mechanical wear and electrical problems that impair the valve's ability to open or close correctly. Symptoms of a failing valve include inadequate water filling the dishwasher, overfilling that can lead to leaks and water damage, unusual noises coming from the valve area, or the dishwasher failing to start. It directly replaces 00628334, 3278459, 33199023, 628334, 9000655808, ABS12394, AP5691117, AP7193108, EAP8729241, PD00075605, PS8729241.
Quick Answer
The 10023852 Genuine OEM Bosch Dishwasher Water Valve fixes Bosch, Thermador, Dacor, and Gaggenau dishwashers with inadequate water filling, overfilling, unusual noise near the valve, or a dishwasher that won't start. 110-127V, 60Hz. Replaces 00628334, 3278459, 33199023, 628334, 9000655808, ABS12394, AP5691117, AP7193108, EAP8729241, PD00075605, PS8729241. If you're also seeing a slow leak near the sump area, be aware that on some Bosch models the sump gasket is built into the sump itself rather than sold as a separate part — a leak there is a different repair from this valve.

Installation Notes
⚠️ Unplug Dishwasher And Shut Off Water Supply Before Starting Disconnect power at the outlet or shut off the circuit breaker, and shut off the water supply before beginning. Wear work gloves. On many Bosch models, pulling the dishwasher out from under the counter gives the best access to the valve and surrounding sump area. Photograph the wiring and hose connections before disconnecting anything. Disconnect the electrical connector and water line from the old valve, remove its mounting hardware, and pull it free. Install the new 10023852 in the same position, reconnect the water line and electrical connector fully, and secure the mounting hardware. If you're troubleshooting a slow leak in this general area rather than a fill problem, be aware that on some Bosch models the sump gasket is built directly into the sump itself and isn't sold as a separate part — a leak there is a different repair involving the sump assembly (diverter, circulation pump, drain pump, and aqua-sensor) rather than this valve. Restore the water supply and power, then run a test cycle to confirm the dishwasher fills correctly with no leaks. Tools needed: Phillips screwdriver, pliers, work gloves.
Frequently Asked Questions
My dishwasher isn't filling with enough water. Is this the right part?
Yes, this is one of the most direct symptoms of a failed water inlet valve. Since this valve is what admits warm water from your household supply into the dishwasher, mineral buildup, mechanical wear, or an electrical fault can prevent it from opening fully, leaving the dishwasher without enough water for a proper wash.
I have a slow leak near the bottom of my dishwasher. Is that this valve too?
Not necessarily. One customer traced a slow, worsening leak on a Bosch dishwasher to the sump gasket, not the water valve — and found that on their model, the gasket is built into the sump itself rather than being a separately replaceable part, requiring a more involved repair pulling the sump apart to address it. If your leak is coming specifically from the sump area rather than showing up as a fill problem, it may be a different repair than this valve replacement.
What causes this valve to fail over time?
The most common cause is mineral buildup from hard water, which can gradually obstruct the valve's internal passages. Mechanical wear and general electrical problems can also affect the valve's ability to open and close correctly over years of use.
Is this an OEM or aftermarket part?
This is a genuine OEM part, manufactured by Bosch to factory specifications — guaranteed fit, materials, and performance. It matches the original solenoid design, flow rate, and connection type of the water inlet valve originally installed in your dishwasher.
