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.
-
Often the door, not the machine Dishwasher will not start
A machine that does nothing, starts and stops, or lights up and never fills. Door and power account for most of these, and both are worth checking before anything is booked.
- No lights at all
- Lights on but nothing happens
- Starts, then stops within a minute

About Bosch dishwasher error code E16
What this one means
Water is not getting into the machine. 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:
- E16, E17, E3300, E3400 — 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 supply valve
- The inlet hose
- The fill valve on the machine
What to try yourself
- Check the valve under the sink is fully open
- Pull the machine forward far enough to see whether the hose is kinked
- Check whether other taps in the kitchen have normal pressure
Then what
Start upstream. A closed or half-closed valve under the sink after other plumbing work is a common and free answer.
