The E17 error on your Bosch Dishwasher means the aquastop or water inlet system has detected a fault, usually linked to low water flow or a blocked inlet valve. Checking the water supply and inlet filter often resolves it without a technician visit.
| Error code | E17 |
|---|---|
| Meaning | Water inlet fault — the dishwasher is not detecting enough water flow within the expected time |
| Severity | Medium — the dishwasher will not run a cycle until resolved |
| Time to fix | 15–40 minutes |
| Tools needed | Adjustable pliers, small bucket, towel |
What the E17 error means
The E17 code appears on Bosch dishwashers when the internal sensors detect that water is not filling the machine at the expected rate. This is usually a water supply or inlet valve problem rather than a major electrical fault. The dishwasher pauses the cycle as a safety measure to prevent running dry or overheating internal components.
Common causes
- Water supply valve under the sink is partially closed or turned off
- Kinked or bent water inlet hose restricting flow
- Blocked or clogged inlet filter screen at the hose connection
- Faulty or stuck water inlet valve inside the dishwasher
- Low household water pressure affecting fill speed
- Aquastop safety device triggered by a detected leak
How to fix the E17 error
- Check the water supply valve. Make sure the shut-off valve under the sink feeding the dishwasher is fully open.
- Inspect the inlet hose. Look behind the dishwasher for kinks or tight bends in the hose and straighten it if needed.
- Clean the inlet filter. Disconnect the hose at the valve end, remove the small mesh filter, and rinse away any debris or limescale.
- Check the Aquastop connector. If your model has an Aquastop hose, inspect it for signs of moisture or tripped safety mechanism and reset if necessary.
- Test water pressure. Run the kitchen tap briefly to confirm normal household water pressure and flow.
- Power cycle the dishwasher. Turn off at the mains, wait two minutes, then restart to clear the error and attempt a fresh cycle.
FAQ
Can I keep using the dishwasher with an E17 error showing?
No, the cycle will not complete properly until the water flow issue is fixed, so it's best to resolve it first.
Does E17 mean the water inlet valve is broken?
Not always — most cases are caused by a closed valve, kinked hose, or blocked filter rather than a faulty part.
Should I call a technician for E17?
If basic checks like the water valve, hose, and filter don't clear the code, a technician should inspect the inlet valve and Aquastop system, similar to how persistent issues on other appliances, such as a Bosch Drill Won'T Start, often need a closer electrical check.
