Bosch Washing Machine Inlet Valve Replacement
An E17 fill fault on a Bosch washer usually means the water inlet valve has failed, an intermediate repair of about 30 to 45 minutes. Test the solenoids first, then replace the valve from the top-rear of the cabinet.
Read the symptom before you open anything#
On a Bosch front-loader, a failing inlet valve almost always announces itself as E17, the fill-timeout code. But E17 has cheaper causes worth eliminating first, so work from the outside in before you pull a panel. The valve itself is a dual-solenoid unit at the upper-rear of the machine, and it doubles as the connection point for the external fill hoses.
Before you start#
| Category | What you need |
|---|---|
| Tools | Torx T20 screwdriver, 10 mm socket wrench, pliers, multimeter, towels |
| Part | Bosch inlet valve (dual-solenoid, part BSH 00622058 or the model-specific equivalent) |
| Time and level | 30 to 45 minutes, Intermediate |
Safety warning: Turn off water supply AND disconnect power. Water pressure remains in the hoses after shutoff — release slowly when disconnecting.

Step-by-step#
1 - Confirm the valve is the fault. With E17 showing, check the easy things first: the wall valves must be fully open, and the small mesh screens inside the hose fittings at the machine end must be clear of debris. If the machine has AquaStop, a red indicator on the hose end means it has tripped. Only then test the valve electrically. Remove the top panel (2 Torx T20 at the rear), unplug one solenoid connector, and read its resistance: roughly 3,000 to 4,500 ohms is normal, while an open circuit means a burned-out solenoid.
2 - Access the valve. With the top panel off (slide it back and lift), the valve sits at the upper-rear. You can see the external hose ports from behind and the internal distribution hoses that feed the detergent drawer from above.
3 - Disconnect the external hoses. From the rear, loosen the hose coupling nuts with the 10 mm socket and pull the fill hoses off the ports. Water will drain from the hoses, so keep towels ready. Note which hose feeds which port if your model separates hot and cold.
4 - Disconnect the internal hoses and wiring. From above, squeeze the spring clamps on the internal distribution hoses, slide them back, and pull the hoses off the valve outlets. Unplug the electrical connector from each solenoid, usually two or three depending on the model.
5 - Remove the valve. The valve is held to the rear panel by two Torx T20 screws or mounting clips. Back them out and lift the valve free from inside the cabinet.
6 - Fit the new valve. Set the replacement in the same orientation and secure the screws. Push the internal hoses back on and slide the spring clamps into place, then reconnect each solenoid connector. From the rear, thread the external hoses hand-tight plus a quarter turn, letting the rubber washers inside the couplings make the seal.
7 - Test under pressure. Open the water supply slowly and watch every joint for leaks before you power up. Restore power and run a fill cycle; a healthy valve fills to wash level in about two to three minutes and directs water into the detergent drawer rather than straight into the drum.
Troubleshooting#
- Overfills after the swap: an internal hose is on the wrong outlet. Swap the distribution hoses.
- Slow fill: debris knocked loose during the work is lodged in a hose screen, or a wall valve is not fully open.
- Leak at an external joint: a missing or damaged coupling washer. Replace the washer, which ships with most new hoses.
- E17 persists with a good valve: the control-board relay may not be firing. Check for line voltage, about 240 volts, at the valve connector during the fill phase.
