What Flash all LEDs but start and run continuously means on a Viking dishwasher

When a Viking dishwasher flashes all LEDs except the Start and Run indicators, it is signaling that AC power was interrupted while a wash cycle was actively in progress. This condition is stored in the control board's memory so the unit can communicate what happened when power is restored. The control board monitors the presence of incoming AC voltage continuously during operation, and when that voltage disappears unexpectedly, the board logs the event and enters this alert state upon the next power-up.

The most common trigger is a momentary power outage, a tripped circuit breaker, or a loose connection at the wall outlet or junction box. Because the dishwasher was mid-cycle when power dropped, the control board does not know whether the cycle completed successfully, so it flags the interruption rather than resuming silently. This protects the wash cycle integrity and alerts the user that the previous run may not have finished.

This is not a component failure code. No sensor, motor, or valve has reported a fault. The condition is purely a record of an external power event. Clearing the alert and inspecting the power supply for stability are the appropriate first steps before assuming any internal component requires attention.

Common causes of Flash all LEDs but start and run continuously

  1. 01

    Momentary power outage or grid interruption

    Wiring / connection

    A brief loss of utility power during a running cycle is the most frequent cause of this alert. Check whether other appliances or lights in the home experienced a flicker or outage at the same time.

  2. 02

    Tripped circuit breaker

    Wiring / connection

    The dishwasher circuit breaker may have tripped during the cycle, cutting AC power to the unit. Inspect the breaker panel for a breaker in the tripped position and reset it before clearing the error.

  3. 03

    Loose or intermittent wall outlet connection

    Wiring / connection

    A loose plug at the wall receptacle or a failing outlet can cause intermittent power loss. Check that the dishwasher power cord is fully seated and test the outlet for consistent voltage.

  4. 04

    Loose wiring at the junction box or terminal block

    Wiring / connection

    For hardwired installations, a loose wire connection at the home junction box or the dishwasher's internal terminal block can cause unexpected power drops. This should be inspected by a qualified technician.

  5. 05

    Faulty door latch interrupting power mid-cycle

    Part replacement

    If the door latch is worn or misaligned, it may briefly signal the control board that the door opened during the cycle, which can cause the unit to cut power to components and register the interruption. Inspect the latch for proper engagement.

Frequently asked questions about Flash all LEDs but start and run continuously

What does Flash all LEDs but start and run continuously mean on a Viking dishwasher?
This flashing LED pattern means the dishwasher detected a loss of AC power while a wash cycle was running. The control board stores this event and displays the alert when power is restored so you know the previous cycle may not have completed. It is not a component failure, but rather a notification about a power interruption event.
How do I clear this error on my Viking dishwasher?
Press and hold the Start button for 3 seconds to reset the control board and clear the alert. After resetting, check your circuit breaker and power supply to make sure power is stable, then restart the wash cycle normally. If the alert returns repeatedly, investigate the power supply for intermittent issues.
Will resetting the dishwasher clear this alert permanently?
Yes, performing the reset by holding Start for 3 seconds will clear the alert. However, if the underlying cause of the power interruption is not resolved, the same alert can return the next time power drops during a cycle. Addressing any loose connections, tripped breakers, or unstable power supply will prevent the alert from recurring.
Is it safe to keep using my Viking dishwasher after this error appears?
In most cases, yes. This alert indicates a past power interruption, not a dangerous internal fault. However, if you suspect a wiring issue or if the circuit breaker is tripping repeatedly, have the electrical circuit inspected before continuing to use the appliance. Persistent breaker trips can indicate an overloaded or faulted circuit that should be addressed promptly.
How much will it cost to fix this issue on a Viking dishwasher?
If the cause is simply a tripped breaker or a momentary outage, there is no repair cost at all beyond your time to reset the unit. If a loose outlet, junction box wiring, or door latch repair is needed, professional service costs typically range from $75 to $250 depending on local labor rates and whether any parts are required. Control board replacement, if ever needed for a related issue, can range from $200 to $500 or more for parts and labor.
