Frigidaire Dishwasher Error Code i00

The i00 code means the dishwasher's electronic control board detected that incoming mains voltage dropped below 180 volts. When this happens, the board suspends all loads and stops the wash cycle to protect the appliance. The problem is most often related to the household power supply rather than the dishwasher itself. Checking the outlet voltage with a multimeter is the recommended first diagnostic step.

Resetting the dishwasher by cutting power at the breaker for a few minutes may temporarily clear the i00 code, but it will return if the underlying low voltage condition is not resolved. The control board will re-detect the fault as soon as supply voltage drops below 180V again. A permanent fix requires identifying and correcting the cause of the low voltage.

If the problem is a loose connection or an overloaded circuit, the repair cost may be minimal, ranging from nothing to around $50 to $150 for an electrician's visit. If the wall outlet or household wiring needs repair, costs can range from $100 to $300 or more. In the less common scenario where the dishwasher's control board is at fault, board replacement typically costs between $150 and $400 depending on parts and labor.

Start by measuring the voltage at the outlet serving the dishwasher using a multimeter. If the voltage is consistently below 180V, contact your utility provider or a licensed electrician to address the supply issue. Also check for loose connections at the outlet, breaker panel, and dishwasher power cord. If supply voltage is normal, the control board itself may need further testing or replacement.

The dishwasher is designed to halt operation when the i00 code triggers, which means it will not run in an unsafe under-voltage state. Do not attempt to force the appliance to run while the fault is active. Continued low voltage conditions can stress motors and other electrical components over time, so the underlying power issue should be addressed before resuming normal use.
