Bosch Washer Er:17 Shows That Aquastop Protection Has Tripped

What Er:17 means

Er:17 belongs to the Aquastop leak protection on Vision front-loaders. According to Bosch there are three possibilities: the Aquastop really did react to water and cut the supply, the Aquastop switch is broken, or the wiring leading to it has failed. Bosch lists finding and removing leaks first, a sign of how likely it thinks a true leak is.

Common causes of Er:17

Water really did reach the Aquastop
Aquastop switch broken and sending a false signal
Wiring to the Aquastop failing

✓ One safe check you can try

1. Close the water tap behind the washer immediately. 2. Look at the floor, under the washer and along the hoses for any water. 3. Dry what you find and watch for new drips. 4. Resist restarting the cycle just to see if the code goes away. Report what you found when you call, including where the water appeared.

! Why to stop there

Restarting sends water back through whatever is leaking, and a small drip becomes a spill on the floor below.
The switch and harness can be wet and still unreliable, so only a proper inspection clears the machine for use.
Guessing it is a false trip puts your flooring and the room beneath at risk.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Er:17Er:17 questions

How does this relate to E23?

They are close cousins. E23 appears on newer Bosch washers, and Er:17 on the Vision platform. Both mean the leak-protection system has acted. Check your display prefix and the model before searching further.

Can the code appear without a visible leak?

Yes. Water can collect inside the base where you cannot see it, and the switch can also misread. A technician needs to look inside before calling it a false alarm.

Do I have to replace the hose?

Only if the Aquastop in the hose is the part that tripped or failed. We inspect it, then give you a written price before replacing anything.
