Bosch Refrigerator E2 Error Code: Ice Maker Sensor Fault

Quick Answer

Bosch E2 is specific to the ice maker system and most commonly appears on Bosch 800 Series and Benchmark refrigerators with built-in ice makers. The ice maker has its own temperature sensor separate from the freezer sensor. E2 triggers when this sensor reads outside the expected range.

Bosch E2 is specific to the ice maker system and most commonly appears on Bosch 800 Series and Benchmark refrigerators with built-in ice makers. The ice maker has its own temperature sensor separate from the freezer sensor. E2 triggers when this sensor reads outside the expected range. The most common cause on Bosch models is frost buildup around the sensor probe inside the ice maker compartment, which insulates the sensor from the actual temperature. A manual defrost of the ice maker area (remove the ice bin, use a hair dryer on low for 5 minutes) often clears E2. If the ice maker sensor has actually failed, it costs $20-40 and is accessible after removing the ice maker assembly.

What Does the E2 Code Mean?

E2 = ice maker sensor fault. Most commonly frost buildup insulating the sensor. Defrost the ice maker area first. If persistent, replace the ice maker sensor ($20-40).

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Frost buildup around ice maker sensor40%
Ice maker sensor failed24%
Sensor wire pinched by ice maker assembly14%
Sensor connector corroded from moisture12%
Ice maker fan not circulating air10%

Symptoms You May Notice

  • E2 on display
  • Ice maker stops making ice
  • Ice tastes stale or has odor
  • Ice maker area shows heavy frost
  • Freezer works fine but ice maker does not

Can you reset a Bosch refrigerator to clear the E2 code?

Unplug for 5 minutes. Most refrigerator error codes clear on power cycle if the underlying issue is resolved.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Remove the ice bin and any loose ice from the ice maker compartment

Remove the ice bin and any loose ice from the ice maker compartment. Use a hair dryer on LOW heat to melt frost around the ice maker assembly and sensor area. This takes about 5 minutes. Do not use high heat.

2

Locate the ice maker temperature sensor (small probe or

If sensor and wiring are good

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

Can frost really cause E2 on my Bosch?
Yes. Frost buildup around the sensor insulates it from the actual temperature. The sensor reads warmer than reality and triggers E2. This is the most common cause and the easiest to fix - just defrost the area.
My Bosch freezer works fine but ice maker shows E2. Why?
The ice maker has its own dedicated temperature sensor separate from the freezer sensor. The freezer can work perfectly while the ice maker sensor has a problem. They are independent circuits.
E2 keeps coming back after defrosting. What is wrong?
Recurring frost in the ice maker area usually means the ice maker door or seal is not closing properly, letting humid air in. Check the ice maker compartment door seal for gaps or damage.
