Viking Dishwasher Error Code AC Power Loss

AC Power Loss means the dishwasher detected that its electrical power supply was interrupted while a cycle was actively running. The control board logs this event when power is restored so the user is aware the cycle did not finish normally. It does not necessarily indicate a broken component. In most cases it reflects a household power event such as a tripped breaker or brief outage.

Yes, pressing and holding the Start button for 3 seconds performs a reset that clears the AC Power Loss flag from the control board. This allows the dishwasher to reinitialize and start a fresh cycle. If the error reappears after resetting with no obvious external cause, further electrical diagnosis is needed to rule out a wiring or board issue.

If the cause is simply a tripped breaker or a brief outage, there is no repair cost beyond your own time to reset the unit. If a technician visit is needed to diagnose wiring or outlet issues, expect service call fees in the range of $75 to $150. Control board replacement, if required, typically adds $200 to $500 or more depending on parts and labor rates in your area.

Start by checking your home's circuit breaker panel for any tripped breakers and reset them if needed. Then press and hold the Start button on the dishwasher for 3 seconds to clear the error and reinitialize the control board. Once reset, run a new cycle to confirm normal operation. If the error returns without a clear power interruption, have a technician inspect the outlet voltage, terminal block wiring, and control board.

In most cases it is not a safety concern. The error is a notification that power was lost mid-cycle, not an indication of a hazardous condition. However, if the error is caused by a repeatedly tripping breaker, that underlying electrical issue should be diagnosed by a qualified electrician before continuing to use the appliance.
