Bosch Refrigerator Error Code 5-1-1

Error code 5-1-1 means the ice maker module has detected that the main voltage supplied to it is too high. The refrigerator shuts down ice production as a protective measure when this condition is detected. The first step is to measure the voltage at the wall outlet to determine whether the issue originates in the home's electrical supply or within the appliance itself.

Yes, high voltage conditions should be taken seriously. Sustained overvoltage can damage the ice maker module and other electronic components in the refrigerator over time. If the wall outlet consistently reads above the normal range, stop using appliances on that circuit and contact your utility provider or a licensed electrician before continuing to operate the refrigerator.

If the issue is a utility supply problem, there may be no cost beyond the service call from your power company, which is often free. Electrical wiring repairs by a licensed electrician can range from $75 to $300 or more depending on the scope of work. If the ice maker control board needs to be replaced, parts and labor combined typically range from $150 to $400 depending on the specific model and service rates in your area.

Start by measuring the outlet voltage with a true-RMS multimeter. If the voltage is above 132V, contact your utility company to report a high-voltage supply problem. If wiring in the home is suspect, have a licensed electrician inspect the neutral connections and branch circuit. If voltage checks out as normal and the error continues, the ice maker control board may need to be replaced.

A reset may temporarily clear the code, but it will return if the underlying voltage problem has not been corrected. Because the ice maker module actively monitors incoming voltage, the fault will be re-triggered as soon as it detects the high-voltage condition again. The root cause in the electrical supply or wiring must be addressed for the error to clear permanently.
