# Wolf convection steam oven error code E103

### What this one means

Two boards inside the appliance have stopped hearing each other, on a convection steam oven, which carries a boiler, a tank and a vent valve that no other oven in this kitchen has. 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 ribbon or harness between the control head and the board that switches the loads
- Either board's own transceiver
- A connector that has worked loose behind a fascia that gets hot every day
- Operating system issue
- Communication between relay board and control board is incompatible

### Worth doing before you call

- Check the water tank is seated and that the drain and fill paths are clear
- Switch the breaker off for thirty seconds and back on, and see whether the display returns

### Then what

A network error is a wiring question before it is a parts question, and the wiring lives behind the control panel. It is not a panel a homeowner should have off with the appliance live.

This code is published for built-in ovens & steam ovens. The [full list of codes](https://wolfmiami.support/error-codes/) has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
