What the E6170 error code actually means

Your Bosch refrigerator is showing an error because there is a problem with a small heating element that evaporates water draining from the inside of the fridge. This heater keeps water from pooling under the refrigerator, and when it stops working correctly, the appliance alerts you with this code. A technician will need to inspect and likely replace the heater or check the wiring connected to it.

Questions people ask about E6170

What does E6170 mean on a Bosch refrigerator?
E6170 indicates a tray heater error, meaning the refrigerator's control board has detected a fault in the circuit that powers the tray heater element. This element sits beneath the defrost drain tray and evaporates collected water. The fault may be caused by a failed heater, damaged wiring, or a control board issue. A technician will need to inspect and test the circuit to identify the root cause.
Is the E6170 error on a Bosch refrigerator a safety concern?
A failed tray heater generally does not pose an immediate safety risk, but it can lead to water pooling under the refrigerator over time, which may cause floor damage or create a slip hazard. Addressing the fault promptly prevents secondary damage. Do not ignore the error for extended periods.
Will resetting my Bosch refrigerator clear the E6170 error code?
A reset may temporarily clear the code from the display, but if the underlying fault in the tray heater circuit has not been repaired, the error will return. Resetting the appliance is not a fix and should only be used as a diagnostic step to observe whether the fault reappears. The root cause must be identified and corrected to permanently resolve the error.
Can I fix the E6170 error on my Bosch refrigerator myself?
Some homeowners with electrical experience may be able to inspect the wiring harness and connectors for obvious damage or loose connections. However, testing the heater element for continuity and replacing components requires basic electrical tools and comfort working inside the appliance. If you are not confident working with appliance wiring, it is best to contact a qualified technician.
How much does it cost to repair a Bosch refrigerator with an E6170 error?
Repair costs vary depending on whether the fault is in the heater element, the wiring, or the control board. Tray heater element replacements are typically among the lower-cost repairs, with parts and labor generally ranging from $100 to $250. Control board replacement is considerably more expensive, often ranging from $300 to $600 or more including labor.
