E17 or F17 on Bosch means the water supply time has been exceeded. Open and check the tap; if the message continues even though water is available, request service.
Distinguishing a water shutoff from a persistent fault
The manufacturer documentation confirms the E17/F17 pair. If the problem started when the appliance was installed or after a vacation, check that the washer valve was not left closed. If there is also no water in the home, wait until the supply is restored before starting a new cycle.
With the tap open, note whether you do not hear water entering or whether it starts to fill and then stops. Do not open the housing or assume right away that the warning points to the inlet solenoid valve.
Additional checks require the E-Nr
The allowable pressure, filter screen cleaning, and recovery procedure belong in the model's installation and operating manual. Do not apply a flow rate, height, or button sequence from another Bosch model. The guide on slow or no filling helps organize the observations without assuming a faulty part.
If the tap is open and the household water supply is working but E17/F17 returns, provide the E-Nr and request a diagnosis. Do not include another code such as E29 in this process without specific confirmation.
Keep the full code in the support request, including the first letter.
