What All LEDs flash (except start) means on a Viking dishwasher

The all-LEDs-flash condition (excluding the Start LED) on a Viking dishwasher is not a component failure code. It is a power interruption notification. When AC power is lost while the dishwasher is actively running a cycle, the control board detects the interruption upon power restoration and enters this alert state to indicate that the cycle was not completed normally. All indicator LEDs illuminate simultaneously as a visual flag, distinguishing this condition from a standard cycle-end state.

The control board retains enough logic to recognize that power was cut mid-cycle rather than the cycle completing properly. Because the dishwasher cannot confirm the state of the wash, rinse, or drain sequence at the time of interruption, it defaults to this alert rather than resuming or completing the cycle automatically. This protects against issues like resuming a heat-dry phase with no water in the tub or skipping a rinse step entirely.

Resetting the unit is straightforward: press and hold the Start button for 3 seconds. This clears the alert from the control board and returns the dishwasher to a ready state. If the flashing LEDs persist after a confirmed power-loss event and a proper reset attempt, the issue may lie with the control board itself or with an intermittent power supply problem such as a loose connection, a failing outlet, or a tripped breaker that is partially resetting.

Common causes of All LEDs flash (except start)

  1. 01

    Household power outage

    Wiring / connection

    A temporary power outage during a running cycle is the most frequent cause. Check if other appliances or lights in the home lost power around the same time.

  2. 02

    Tripped circuit breaker

    Wiring / connection

    The dishwasher's dedicated circuit breaker may have tripped mid-cycle due to an overload or a momentary fault. Check the breaker panel for any tripped breakers and reset them before attempting to clear the dishwasher error.

  3. 03

    Loose or intermittent wall outlet connection

    Wiring / connection

    A loose connection at the wall outlet or junction box can cause brief power interruptions that the control board registers as a full power loss. Inspect the outlet and wiring connections for security.

  4. 04

    Start button or control board fault

    Part replacement

    If the LEDs continue flashing after a confirmed power-loss event and a 3-second Start button reset, the control board may not be processing the reset command correctly, pointing to a potential board or button failure.

  5. 05

    Power supply cord or internal wiring issue

    Part replacement

    A damaged power cord or a loose internal wiring connection can cause intermittent power loss events. This would require inspection of the cord and internal connections to the control board.

Frequently asked questions about All LEDs flash (except start)

What does All LEDs flash (except start) mean on a Viking dishwasher?
This LED pattern means the dishwasher experienced an AC power loss while a wash cycle was actively running. The control board uses this display to alert you that the cycle was interrupted and did not complete normally. It is not a component failure warning. Pressing and holding the Start button for 3 seconds will reset the unit.
How do I fix the all-LEDs-flashing condition on my Viking dishwasher?
Press and hold the Start button for 3 seconds to reset the control board and clear the alert. Before doing so, confirm that power to the unit is stable by checking your breaker panel and ensuring the outlet is functioning. Once reset, you can start a new cycle from the beginning.
Will simply resetting the dishwasher clear the flashing LEDs permanently?
Yes, in most cases the 3-second Start button reset will fully clear the condition if the cause was a genuine one-time power interruption. If the LEDs begin flashing again after reset and normal operation, this points to a recurring power supply problem such as a tripping breaker, a loose connection, or an intermittent control board issue that needs further diagnosis.
Is it safe to use my Viking dishwasher after this error appears?
Yes, it is safe to use once you have performed the reset. The flashing LEDs indicate a past power interruption, not an active electrical hazard. However, if you notice the condition recurring frequently without an obvious power outage explanation, have the wiring, outlet, and control board inspected before continuing regular use.
How much does it cost to repair a Viking dishwasher that keeps showing this error?
If the cause is a tripped breaker or a loose outlet connection, there may be little to no cost involved. If a control board replacement is needed, parts and labor costs typically range from $200 to $500 or more depending on the specific model and your location. A service call for diagnosis alone generally runs in the $75 to $150 range.
