Miele Refrigerator Error Code 4-1-1

Error code 4-1-1 on a Miele refrigerator indicates an internal fault within the icemaker system. The fault can originate from a failed water inlet heater at the back of the unit or from a component failure inside the icemaker assembly itself. The icemaker will not operate normally until the underlying cause is identified and corrected.

Start by turning the refrigerator off and then back on to see if the fault clears. If the code returns, inspect the water inlet heater located at the back of the appliance to confirm it is functioning correctly. If the heater is operational but the fault persists, the icemaker assembly will need to be replaced.

Repair costs vary depending on whether the fault requires only a water inlet heater replacement or a full icemaker assembly replacement. A water inlet heater repair will generally be less expensive, while replacing the complete icemaker unit on a Miele appliance can range from several hundred dollars into the higher hundreds when factoring in parts and labor. Obtaining a diagnosis from a qualified technician before ordering parts is advisable.

Switching the appliance off and back on is the recommended first step and may clear the code if the fault was caused by a temporary control error. However, if the error returns after a power cycle, a physical component such as the water inlet heater or the icemaker unit itself has likely failed and will need to be inspected or replaced.

This fault code relates specifically to the icemaker and does not affect the main refrigeration or freezing functions of the appliance. Food stored in the refrigerator and freezer compartments should remain safe. However, ice production will be disrupted until the fault is resolved.
