What it looks like from the kitchen
The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.
-
Door, power or supply Washer will not start
A machine that does nothing, or one that lights up and never fills. The door lock and the water supply account for most of it, and both are worth a minute before booking.
- No response at all
- Lights on but the cycle never begins
- Starts, then stops without filling

About Bosch error code E17
What this one means
The filters in the water connection are blocked, or the pressure is too low. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.
The other ways your machine may say it
The same condition is published under more than one label, because it has been carried across generations of this appliance:
- E17, F17, F29 — the same condition, on machines of different ages
What the code covers
A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:
- The mesh filter in the inlet fitting
- The filter in the leak-protection hose
- Genuinely low supply pressure
What to try yourself
- Turn the tap off
- Take the hose off the tap and clean the filter with a small brush
- Never immerse a leak-protection hose in water — there is an electric valve in it
Then what
In a hard-water city those inlet screens block on a schedule, and cleaning them is a five-minute job with the tap off. The warning about not immersing the hose is the manufacturer's and it is worth respecting.
This code is published for washers. The full list of codes has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
