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 a protection Dishwasher will not start
A machine with lights on that will not run, or one that shows nothing at all. On this platform a machine that refuses to start is usually protecting itself, and the code says which protection.
- Lights on, nothing happens
- A code showing before the cycle begins
- Dead panel, no lights at all

About Thermador dishwasher error code E27
What this one means
The voltage reaching the machine is below what it will run on. 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:
- E27, E9001, E9240, E92-40, E92 — 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 circuit the machine is on
- The building's supply
- A long or shared run to the outlet
Worth doing before you call
- Check whether other things on the same circuit dim or stutter at the same time
Then what
This is not a problem in the machine and replacing parts will not change it. It is an electrician's call.
