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.

About Bosch dishwasher error code E01
What this one means
The control board cannot drive the heat pump motor. 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:
- E01, E0100 — 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 motor itself
- The circuit on the board that drives it
- The wiring between the two
Worth doing before you call
- Cut power at the breaker for thirty seconds and try one cycle
Then what
If it returns, this is board and pump territory rather than anything reachable from inside the tub.
