What All flash means on a Viking dishwasher

The "All flash" condition on a Viking dishwasher indicates that the control board has detected a power loss event. When all indicator lights on the control panel flash simultaneously, the machine's control system is signaling that it lost power mid-cycle or during standby, and the board is alerting the user that the previous operating state was interrupted. This is essentially a watchdog function built into the control electronics to prevent the unit from resuming an unknown or incomplete cycle without user acknowledgment.

The most common trigger is a brief interruption to the household power supply, such as a momentary brownout, a tripped circuit breaker, or a loose connection at the wall outlet or junction box. The control board monitors incoming voltage, and even a short drop below operating threshold is enough to log this condition and cause the all-flash response on the panel.

Because this is a power-loss notification rather than a hardware fault, the first diagnostic step is a full reset. This typically involves canceling the current cycle, cutting power to the unit at the breaker for 60 seconds, and then restoring power to allow the control board to reinitialize. If the all-flash condition returns repeatedly without an obvious external power issue, the wiring connections to the control board, the door latch switch circuit, or the control board itself may warrant closer inspection.

Common causes of All flash

  1. 01

    Household power interruption

    Wiring / connection

    A momentary brownout, brief outage, or voltage sag is the most frequent cause. Check if other appliances or clocks on the same circuit were also reset.

  2. 02

    Tripped circuit breaker

    Wiring / connection

    An overloaded or faulty circuit breaker can cut power to the dishwasher and trigger the all-flash alert. Inspect the breaker panel and reset any tripped breakers before testing.

  3. 03

    Loose power connection at outlet or junction box

    Wiring / connection

    A loose wire at the wall outlet, terminal block, or the dishwasher's direct-wire connection can cause intermittent power loss. Check and tighten all connections at the power source.

  4. 04

    Faulty door latch or latch switch

    Part replacement

    If the door latch switch fails or loses contact, the control board may interpret the interruption as a power loss event. Inspect the latch assembly for physical damage or misalignment.

  5. 05

    Failing control board

    Part replacement

    If the all-flash condition recurs repeatedly after successful resets with no external power issues found, the control board itself may be intermittently losing power or failing to retain state. Board replacement would be required in this case.

Frequently asked questions about All flash

What does All flash mean on a Viking dishwasher?
The All flash condition means the dishwasher's control board detected a loss of power. All indicator lights flash simultaneously to alert you that the unit's previous operating state was interrupted and a reset is needed before normal operation can resume. It is a notification function, not necessarily a sign of a component failure.
Will resetting my Viking dishwasher clear the All flash condition?
In most cases, yes. Turn off the circuit breaker supplying the dishwasher, wait at least 60 seconds, then restore power to allow the control board to reinitialize. If the all-flash condition clears and does not return, the cause was likely a one-time power interruption. If it returns repeatedly, further diagnostic inspection is needed.
How do I fix the All flash error on a Viking dishwasher?
Start by resetting the unit at the breaker for 60 seconds, then restore power and attempt to run a cycle. Also check that the circuit breaker for the dishwasher is fully engaged and that all power connections are secure. If the condition keeps coming back, inspect the door latch switch and wiring connections before considering a control board replacement.
Is it safe to use my Viking dishwasher when the All flash error is showing?
The dishwasher will not operate normally while all lights are flashing, as the control board requires a reset before accepting new commands. The condition itself does not indicate an immediate safety hazard, but you should investigate repeated occurrences to rule out a wiring problem or failing component before continued use.
How much does it cost to repair a Viking dishwasher with the All flash error?
If the cause is simply a power interruption, there is no repair cost beyond your time to reset the unit. If a door latch switch needs replacement, parts and labor typically range from $75 to $200 depending on your location and service provider. A control board replacement, if required, generally runs between $200 and $500 or more for parts and labor combined.
