Bosch Dishwasher Error Code E17
E17 belongs to the same fill-fault family as E16: the machine is not happy with how water is entering during the fill stage. Start with the free external checks, because taps, hoses and inlet screens cause most of these. If everything outside the machine is fine, the fault is in the filling system itself.
Also shown as: E3400
Common causes
- Low water pressure or tap not fully open
- Kinked inlet hose
- Clogged inlet filter screen
- Fault in the filling system or inlet valve
What to check, in order
- Open the supply tap fully and try the cycle again.
- Check the inlet hose for kinks or damage.
- Clean the small filter screen where the inlet hose connects, with the tap turned off first.
- If the code returns with a good supply, book a service visit.
Clear the code and test
- Fix what the checks above found first — a filter cleaned, a hose straightened, the spray arms freed. Clearing the code without fixing the cause only brings it back.
- Close the door, plug the dishwasher back in (or restore its breaker) and make sure the water tap is open.
- Run the shortest programme and stay nearby for the first minutes, watching for leaks and listening for the drain pump.
- If the programme finishes with no code, the fault is cleared. If the code returns, write down the code and when it appeared before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code E17, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
