Bosch Dishwasher Water Inlet Valve Parts — Models & Compatibility

Your Bosch dishwasher won't fill with water, or it's taking forever to start the wash cycle. That clicking sound you hear? It's probably the water inlet valve trying — and failing — to open. The 622058 water inlet valve is one of the most common replacement parts for Bosch and Thermador dishwashers, fitting over 300 models across the SHE and SHX series.

Is This the Right Part for Your Model?

This valve fits Bosch SHE3AR and SHX3AR series models manufactured between 2012-2018. Your model number is stamped on the side edge of the dishwasher door — open it and look along the top or side frame. It'll be a combination like "SHE3AR75UC/06" or "SHX3AR55UC/07". The numbers after the slash indicate your production series, and this part works across /06 and /07 variants.

About This Replacement Part

The water inlet valve controls the flow of water into your dishwasher's tub. It's got dual solenoids that open and close electrically when the control board signals for water. When it fails — and they all eventually do — you'll notice your dishwasher either won't fill at all or underfills, leaving dishes dirty. The most common failure mode is a defective solenoid that can't generate enough magnetic force to open the valve gate. Sometimes it's simpler: debris from your home's water supply clogs the mesh screen inside the valve, choking off water flow. Either way, you're stuck with a dishwasher that can't wash.

Common Models Using This Part

This valve is standard equipment across Bosch's 300 Series and Thermador Professional Series dishwashers. Below are the most common models, though the complete compatibility list includes over 300 variants:

What Makes This Valve Fail

Hard water is the biggest enemy. Mineral deposits build up on the solenoid plunger over years of operation, eventually preventing it from moving freely. You'll hear the valve clicking as electricity energizes the coil, but nothing happens. The other culprit is the plastic valve body itself — years of hot water cycling can make it brittle, leading to hairline cracks that leak or prevent proper sealing. If you've got low water pressure in your house (below 20 psi), the valve struggles to open fully even when it's working correctly.

Replacing vs. Repairing

Don't bother trying to clean or repair a failed inlet valve. The solenoids are sealed units, and even if you manage to flush out debris, you're just delaying the inevitable. A new valve costs $50.99 and takes about 20 minutes to swap out. You'll need to shut off the water supply, disconnect the fill hose, unplug the wire harness, and reverse the process with the new valve. It's a moderate DIY job — no special tools required beyond a pair of pliers and a towel for the water that'll drip out.

Verify Before You Order

Double-check your model number against the compatibility chart. Bosch uses different valves for different series, and installing the wrong one means another trip to the parts store. The 622058 supersedes older part numbers 00622058, AP4927070, and PS8728724 — if you've got those listed in your service manual, this is the current replacement.
