E17
Bosch Washing Machine
Severity: CriticalWhat Does This Error Mean?
The E17 error on your Bosch washer means water is filling the drum when it should not be. The machine detected unexpected water entering during a cycle or while idle. This is a serious error because it can lead to overflow and flooding.
Affected Models
- Bosch 300 Series
- Bosch 500 Series
- Bosch 800 Series
- Most Bosch front-load washers
Common Causes
- The water inlet valve is stuck open and letting water through continuously
- Debris or sediment is preventing the inlet valve from closing fully
- The water pressure sensor is giving false readings to the control board
- A faulty control board is sending incorrect signals to the inlet valve
- Backflow from the drain standpipe is pushing water into the machine
How to Fix It
-
Turn off the washer and immediately shut off both water supply valves behind the machine. This stops any more water from entering.
This is urgent. An open inlet valve can cause flooding if the supply stays on.
-
Unplug the washer from the wall. Wait five minutes, then plug it back in. Check if the error clears.
A power reset can sometimes fix a temporary glitch in the control board.
-
Turn the water supply back on slowly and watch for any water entering the drum while the washer is off. If water flows in while the machine is off, the inlet valve is stuck open.
This confirms the inlet valve needs replacing.
-
Check that the drain hose is not too low or submerged in standing water. Backflow from the drain can trigger E17.
The drain hose should loop up to at least 24 inches above the floor.
-
If the inlet valve is stuck open, it must be replaced. Turn off the water supply and call a technician.
The inlet valve part costs $40–$90. Do not run the washer until it is fixed.
When to Call a Professional
E17 usually requires a technician because it often involves a faulty inlet valve or control board. Do not continue running the washer with this error. Expect repair costs of $150–$350 depending on whether the valve or board needs replacing.
Frequently Asked Questions
Can the E17 error cause my washer to flood?
Yes — if the inlet valve is stuck open and the water supply is on, water will keep filling. The AquaStop system should catch most cases. But shutting off the supply valves yourself is the safest step.
What is a water inlet valve?
It is an electrically controlled valve at the back of your washer. It opens to let water in when the machine needs it. When the cycle does not need water, it closes. If it gets stuck open, water flows in continuously.
Can I test the inlet valve myself?
You can do a simple test. With the washer off and unplugged, turn on the water supply. If water still flows into the drum, the valve is stuck open. Replacing the valve requires basic tools but a technician is recommended.
