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.

Diagnosed by behavior Refrigerator not cooling
A refrigerator running warm, cooling unevenly, or holding overnight and drifting by day. This equipment publishes almost no codes, so what it is doing matters more here than on anything else on this site.
- One compartment warm, the other fine
- Compressor running almost constantly
- Frost building at the back of the freezer
On the same appliance
What else belongs to the refrigerators
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

About Bosch refrigeration error code E or D
What this one means
The refrigerator has an error message it does not describe further.
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:
- A letter on the refrigerator display — how a model with no digital display says it. On that machine, the lights are the code
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:
- Anything the appliance logs
What to try yourself
- Switch the appliance off
- Disconnect it from the power supply at the plug or the breaker
- Reconnect after five minutes
Then what
The third and last of the refrigeration codes, and the least specific. If it survives five minutes disconnected, the useful information is what the compartments are actually doing rather than what the display says.
This code is published for refrigerators and wine & beverage storage. The full list of codes has the rest.
