Bosch Dishwasher Error Code 0110

Error code 0110 on a Bosch dishwasher signals an inverter error caused by line overvoltage. The inverter, which controls the wash pump motor, detected that the incoming mains voltage exceeded its acceptable input range and shut down to prevent damage. The first step is to check the voltage at your wall outlet or terminal block with a multimeter to confirm whether the supply voltage is abnormally high.

The error itself means the dishwasher has already shut down to protect its internal components, so the immediate risk is low. However, the underlying cause, which is overvoltage from the electrical supply, can be hazardous to all appliances in your home and potentially indicates a wiring or utility problem. Do not continue running the dishwasher until the source of the overvoltage has been identified and resolved.

Repair costs vary depending on the cause. If the issue is a power surge or elevated utility voltage, costs may be limited to an electrician's service call, typically in the range of $75 to $200. Replacing an inlet filter board or inverter module adds parts costs, and total repair bills for component replacement can range from $150 to $450 or more depending on labor rates in your area.

Start by measuring the mains voltage at the outlet supplying the dishwasher to confirm it is within the normal range for your region. If voltage is elevated, the issue lies with your home's electrical supply or a recent power surge, and you should contact an electrician. If voltage is normal, inspect all wiring connections for damage or corrosion. Persistent errors at normal voltage may indicate a failed inlet filter board or inverter module that requires professional replacement.

A reset may clear the error code temporarily, but if the root cause of the overvoltage has not been addressed, the code will return as soon as the dishwasher attempts to operate again. Resetting is useful for confirming whether the error was caused by a one-time transient surge, but a permanent fix requires diagnosing and correcting the actual voltage issue or replacing the faulty component.
