## About Thermador connectivity error code H1073

### What this one means

The phone is not on the home network it is trying to join the appliance to. 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 phone sitting on mobile data
- The wrong network chosen

### What to try yourself

- Put the phone on the same Wi-Fi the appliance will use, then repeat

### Then what

Common in a large house where the phone has hopped to a second access point.

This code is published for dishwashers and wall ovens & steam ovens and professional ranges and cooktops & rangetops and built-in refrigerators & columns and range hoods & ventilation.
