What does the Bosch E17 error code mean?
E17 indicates the machine is taking too long to fill with water. The most common causes are a turned-off or partially closed tap behind the machine, a kinked inlet hose, or a blocked inlet filter mesh. Low water pressure in your home can also trigger this code.
How to fix the Bosch E17 error code
- Check the cold water tap behind the machine is fully open — it is easy to accidentally knock it closed.
- Inspect the blue (cold) inlet hose for any kinks or sharp bends restricting flow.
- Turn off the tap, unscrew the inlet hose from the back of the machine, and look at the small mesh filter inside the valve inlet. If it is clogged with limescale or grit, rinse it under a running tap.
- Reconnect the hose securely, reopen the tap, and restart the machine.
- If the problem persists, check your home’s water pressure — if other taps are also running slowly, this is a supply issue rather than a machine fault.
