Bosch Refrigerator Error Code Er Et

Er Et means the horizontal switch on the ice maker is not closing during the ice making cycle. This switch acts as a position sensor, and when it fails to close, the refrigerator interrupts ice production to avoid an incomplete or stuck cycle. The error points specifically to a fault in the ice maker's switching mechanism, wiring, or related components.

The refrigerator's cooling and food preservation functions are generally not affected by the Er Et error, as the fault is isolated to the ice maker system. Ice production will be stopped, but your food should remain safe. You can continue using the refrigerator for cooling while you arrange for diagnosis and repair of the ice maker.

Repair costs depend on the specific cause of the fault. If the issue is a minor obstruction or a loose connector, costs may be limited to a service call fee, typically ranging from $75 to $150. If the horizontal switch or the entire ice maker module needs replacement, parts and labor combined can range from $150 to $400 or more depending on your location and the specific model.

Some causes of Er Et are DIY-accessible, such as clearing ice or frost buildup around the horizontal switch or reseating a loose wiring harness connector. However, testing switch continuity and replacing components requires basic electrical knowledge and a multimeter. If you are not comfortable working with appliance wiring or internal ice maker components, a qualified technician should perform the repair.

A power reset may temporarily clear the error display, but if the underlying cause is a faulty switch, damaged wiring, or a seized mechanism, the code will return once the ice maker attempts another cycle. A reset is useful for confirming whether the fault is intermittent, but it does not substitute for diagnosing and repairing the horizontal switch and related components.
