What Quick Flashing Means
On Viking's older DFUD-series undercounter dishwashers, a flashing "Quick" wine-glass-with-arrows icon flags valve leakage — documented directly in this platform's own owner's manual.
Common Causes of Quick Flashing
- Inlet valve is failing to seal fully closed between cycles
- Valve seat has worn from age or mineral buildup
- Debris lodged in the valve is holding it slightly open
🔧 One Safe Check You Can Try
Shut off the water supply valve to the dishwasher and don't run another cycle until a technician has confirmed and stopped the source.
⚠ Why You Shouldn't Go Further Than That
- Running the dishwasher again while a valve is confirmed leaking risks a flooded cabinet or floor before the problem is ever addressed.
- Replacing the valve means working on the pressurized water-supply connection, which is best handled with the line properly isolated first.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
