Bosch Refrigerator Error Code E15 — What It Means & How to Fix It

What Does This Error Mean?

The E15 error means your Bosch refrigerator's ice maker temperature sensor has a fault. This only applies to models that have a built-in ice maker. The ice maker may stop producing ice until the issue is resolved.

Affected Models

Bosch Series 4 Refrigerator
Bosch Series 6 Refrigerator
Bosch Series 8 Refrigerator
Bosch Benchmark Series Refrigerator

Common Causes

Ice maker temperature sensor has failed or gone out of range
Wiring to the ice maker sensor is loose or damaged
Ice buildup around the sensor causing false readings
Ice maker module itself has developed a fault
Control board not reading the sensor signal correctly

How to Fix It

Unplug the refrigerator for 5 minutes to reset the control board.

This is the simplest first step and clears many temporary sensor errors.
Plug back in and check if E15 is gone.

If the error clears and ice production resumes, watch for it returning over the next few days.
Turn the ice maker off using its power switch (usually a lever or button inside the freezer).

Leave it off for 10 minutes, then turn it back on. This resets the ice maker module independently.
Check for ice buildup around the ice maker and its sensor.

Remove any visible ice accumulation by hand or with a warm, damp cloth. Do not use sharp tools.
If E15 keeps returning, the ice maker temperature sensor likely needs replacement.

Your model number is on a sticker inside the door frame. Use it to find the correct sensor part for your specific ice maker unit.

When to Call a Professional

If the error persists after cleaning and resetting, the ice maker module may need full replacement. A technician can test the sensor and module with a multimeter to confirm which part has failed.

Frequently Asked Questions

Will E15 affect my refrigerator's cooling — or just the ice maker?

Usually just the ice maker. Your fridge and freezer compartments should continue cooling normally. E15 is considered a minor error because it does not threaten food safety.

My Bosch fridge does not have an ice maker — why am I seeing E15?

Some Bosch models display E15 if there is a fault on a circuit that is wired for an ice maker even when no ice maker is installed. In this case, the error is usually harmless but should still be investigated. A technician can disable the unused circuit if needed.

How long does it take for the ice maker to start working again after fixing E15?

After the repair, give the ice maker 24 hours to fully restart. The first batch of ice may take several hours to produce. Make sure the freezer temperature is at or below 0°F (-18°C) for ice production to work.
