What this one means
The appliance says it is not wired the way it expects. 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.
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 terminal block at installation
- A missing bridge between terminals
- One phase absent
Then what
This one is an installation question and belongs to whoever made the connection.
