## About Thermador connectivity error code H1077

### What this one means

The appliance is not answering on the network the phone is 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:

- **H1077, H1081** — 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:

- A 5 GHz-only network
- Guest isolation on the router
- An appliance out of range of the access point

### What to try yourself

- Check the router is offering a 2.4 GHz band and that the phone is on it

### Then what

Several of these appliances will not use 5 GHz at all. A modern router that hides both bands behind one name is the usual reason this never works.

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.
