The E17 error on your Bosch Dishwasher means the appliance has detected a problem with water flow, usually linked to the aquastop system or the flow meter that measures how much water enters the machine. This code often triggers a safety shutdown to prevent flooding or overfilling, so it should not be ignored.
| Error code | E17 |
|---|---|
| Meaning | Water inlet fault — flow meter or aquastop valve issue detected |
| Severity | Medium — the dishwasher usually stops mid-cycle to prevent water damage |
| Time to fix | 15–40 minutes |
| Tools needed | Screwdriver, towel, adjustable pliers |
What the E17 error means
Bosch dishwashers use a flow meter to track how much water flows into the tub during each fill cycle. When the E17 code appears, the control board has detected that water is either filling too slowly, too quickly, or not registering correctly at the flow meter. This is often paired with reduced water pressure or a partial blockage somewhere in the supply line.
In many cases, the fault is not with the electronics but with something physical blocking or restricting water flow, such as a kinked hose, a clogged inlet filter, or a failing aquastop valve.
Common causes
- Low household water pressure feeding the dishwasher
- A kinked, twisted, or pinched water inlet hose
- A clogged inlet filter or debris trapped in the water valve screen
- A faulty or worn aquastop valve that restricts flow
- A failing flow meter sensor that sends incorrect readings to the control board
- A partially closed water supply tap under the sink
How to fix the E17 error
- Check the water supply valve: Make sure the tap feeding the dishwasher is fully open. A partially closed valve is a common and easy-to-fix cause.
- Inspect the inlet hose: Pull the dishwasher out slightly and check the hose for kinks, twists, or pinches that could be restricting water flow.
- Clean the inlet filter: Turn off the water supply, disconnect the hose, and clean out the small mesh filter where the hose connects to the machine. Debris here is a frequent culprit.
- Test water pressure: Run the tap the dishwasher connects to and check that pressure is strong and consistent. Weak pressure can trigger flow-related faults.
- Reset the dishwasher: Turn off power at the wall for two minutes, then restart the appliance to see if the error clears once water flow is restored to normal.
- Call a technician if the error persists: If the aquastop valve or flow meter itself has failed, these parts typically need professional replacement, similar to how sensor issues in other Bosch tools sometimes need expert diagnosis — much like troubleshooting steps used when a Bosch Drill Battery Not Connecting requires checking connection points before replacing parts.
FAQ
Can I keep using the dishwasher with an E17 error showing?
No. The error usually stops the cycle to prevent overfilling or flooding, so it's best to fix the cause before running another cycle.
Is E17 always caused by low water pressure?
Not always. Low pressure is the most common trigger, but a blocked filter, kinked hose, or faulty valve can cause the same code.
Do I need a professional to fix this?
Simple causes like a closed valve or blocked filter can be fixed yourself. If the aquastop valve or flow meter has failed, a technician will need to replace the part.
