What the 1-3-1 error code actually means

Your Miele refrigerator has detected a problem with the temperature sensor inside the icemaker, and that sensor is built into the icemaker unit so it cannot be replaced on its own. If turning the fridge off and back on does not clear the error, the whole icemaker assembly will need to be replaced. Your refrigerator will continue cooling normally, but the icemaker will not function properly until the issue is resolved.

Questions people ask about 1-3-1

What does 1-3-1 mean on a Miele refrigerator?
Error code 1-3-1 on a Miele refrigerator indicates a sensor fault in the icemaker assembly. The icemaker contains a built-in temperature sensor, and the control board has detected that the sensor signal is invalid or absent. Because the sensor is integrated into the icemaker unit and cannot be replaced separately, a persistent fault requires replacing the entire icemaker assembly.
Can I fix the 1-3-1 error myself without replacing any parts?
The first step is always to perform a power cycle by turning the refrigerator off and back on. You can also check that the wiring harness connector to the icemaker is fully seated and free of visible damage or corrosion. Beyond those steps, there is no DIY repair path since the faulty sensor is not accessible or replaceable as a standalone part.
How much does it cost to fix a Miele refrigerator showing error code 1-3-1?
If the error requires replacing the icemaker assembly, repair costs typically include the part itself plus labor. Icemaker assembly parts for Miele refrigerators generally range from around $150 to $400 or more depending on the specific model, and professional labor costs vary by region but commonly add another $100 to $250. Getting a quote from a Miele-authorized service technician before proceeding is recommended.
Will resetting my Miele refrigerator clear the 1-3-1 error?
A reset, meaning switching the appliance off and then back on, may clear the error if it was caused by a temporary electrical glitch or power fluctuation. If the code returns after the power cycle, the fault is persistent and a reset will not resolve it. In that case, the icemaker assembly needs to be replaced.
Is it safe to keep using my refrigerator when the 1-3-1 code is active?
Yes, the 1-3-1 code is specific to the icemaker sensor and does not affect the main refrigeration or freezer cooling functions. Your food will remain properly cooled and frozen. The icemaker may not produce ice reliably while the fault is active, but there is no safety risk associated with continuing to use the appliance.
