How to Replace Bosch Washing Machine Inlet Valve

Match the OEM valve first#

The BSH 00622058 is the dual-solenoid inlet valve on many standard-width Bosch front-loaders from 2010-2020; some models use 00609588 or 00617612 instead. It has two solenoid coils (two electrical connectors on top), three outlet ports (cold wash, hot wash, and pre-wash/detergent flush), and Bosch's standard mounting-tab spacing. Aftermarket valves can differ in flow rate or connector orientation and may trip E17, so verify the exact number against your model — the label is on the valve, and on the door-frame sticker.

Tools and safety#

• Tools: Torx T20 screwdriver, a 10mm socket, pliers, a multimeter
• Time: 30-40 minutes · Difficulty: intermediate
• Safety: shut off the water and unplug the machine, and depressurize the fill hoses before you disconnect them.

Step-by-step#

1. Confirm the part#

Read the number off the existing valve (visible after the top panel comes off) or cross-reference your model on the BSH parts site. Check for the two solenoids, three ports, and matching mounting tabs.

2. Remove the top panel#

Back out the two Torx T20 screws at the rear edge, slide the panel back about an inch to clear the front hooks, and lift it off. The valve sits at the upper-rear-left with its hoses passing through the rear panel.

3. Photograph everything#

Before touching anything, shoot the electrical connectors (which solenoid each feeds), the internal distribution hoses (which outlet port each uses), and the external hose positions (hot versus cold). On the 00622058, the outer ports are usually cold/main wash and hot/pre-wash, with the center distribution port feeding the main detergent compartment.

4. Disconnect and remove#

Turn off the water, undo the external hoses (10mm socket on the coupling nuts), release the internal hose spring clamps with pliers and pull them off, and unplug the two electrical connectors. Remove the two Torx T20 mounting screws and lift the valve out.

5. Install the new valve#

The 00622058 drops into the same spot. Fit the two Torx T20 screws, reconnect the internal hoses to their matching ports using your photos, and click the keyed electrical connectors on (they only fit one way). Reconnect the external hoses at the rear.

6. Test with AquaStop#

Turn the water on gradually. On AquaStop models the module on the inlet hose should show a green indicator. Start a wash and confirm the right temperature reaches the drum, the water routes through the detergent drawer rather than straight into the tub, and nothing leaks at any joint.

OEM vs aftermarket#

Troubleshooting#

• Aftermarket valve trips E17 though it works: its solenoid resistance is outside the range the board expects; fit the OEM part.
• Water goes to the wrong compartment: the distribution hoses are on the wrong outlet ports — recheck your photo and swap them.
• Valve buzzes loudly: normal for the first couple of fills as the diaphragm seats; persistent buzzing means a defective valve.

When to call a professional#

Get help if the valve is not the fault after replacement (a fill or board issue), if the machine still will not fill, or if you are not comfortable working around the mains water connections.
