Miele Dryer Error Code F46

F46 indicates an internal display fault on the selection module, specifically that the display driver for the LCD module is defective. The selection module is the user interface board containing the control display and input buttons. This fault is internal to that module and points to a hardware failure of the display driver circuit. A power cycle can be attempted first, but replacement of the selection module is the standard repair.

Because the fault is internal to the selection module's PCB, field repair of the individual display driver IC is not a practical option. The repair involves exchanging the entire selection module with a compatible replacement unit. A knowledgeable DIYer comfortable working with appliance control boards can perform this swap, but the dryer must be unplugged before any work begins.

The cost to resolve F46 depends primarily on the price of the replacement selection module and labor if a technician is hired. Selection module parts for Miele dryers typically range from around $80 to $250 or more depending on the specific model. Adding professional labor, total repair costs commonly fall in the range of $150 to $400. Obtaining a model-specific part quote before proceeding is recommended.

A full power cycle by unplugging the dryer for several minutes may clear F46 if the fault was caused by a temporary glitch in the control system. However, if the display driver circuit has physically failed, the code will return after power is restored. A persistent F46 code after a reset indicates the selection module needs to be replaced.

F46 is a display and interface fault, not a safety-critical fault related to heating, venting, or motor systems. However, if the control panel display is non-functional, you may lose the ability to properly monitor or control the dryer's settings and cycle status. It is advisable to resolve the fault before continued regular use to ensure full control of the appliance.
