What Both Lights Continuous (Pan Flood) means (viking dishwasher pan flood)
A viking dishwasher pan flood condition is shown when both indicator lights are on continuously, rather than in a blink pattern. Viking dishwashers (verified on the 451 Series) have no numeric display — instead, faults are shown as a two-light blink pattern: the Pots/Pans light flashes to give the first digit and the Normal Wash light flashes to give the second. The base anti-flood system has detected water under the tub and tripped to stop a leak from spreading. It should be treated as a real leak until proven otherwise.
Symptoms to look for
The signs below help confirm you are dealing with this condition rather than a different fault on your Viking Dishwasher. You may see one of them or several together, and they can build up gradually or appear suddenly after a power event, a long door opening, a spill, or recent service.
- Both Pots/Pans and Normal Wash lights stay on continuously
- The dishwasher stops and will not resume
- The drain pump may run to clear the base
- Water may be visible under or around the unit
Common causes
Several different faults can produce these symptoms. Working through the most likely causes in order helps separate a quick, owner-level check from a problem that needs trained service and the correct Viking parts.
- Internal leak — a seal, hose, or sump leaks into the base
- Door seal leak — water escapes the tub at the door
- Over-fill or spray leak — water reaches the base tray
- Float/sensor fault — less common, the float trips without water
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where high-voltage parts, gas, the sealed refrigeration system, or a compressor are involved, and hand the rest to a qualified technician.
- Turn off the water supply and switch the dishwasher off at the breaker.
- Look for water under and behind the unit and check the inlet and drain connections.
- Do not keep restarting while water is present in the base.
- Because a leak can damage flooring, book service to find and seal the source.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the base anti-flood float/sensor, door seal, hoses, sump, and pump seals. The correct part for your Viking Dishwasher is matched from the model and serial number, and genuine Viking components are fitted through trusted parts suppliers rather than generic substitutes so that performance, safety, and the appliance’s long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.
When to call a technician
A Pan Flood condition needs a technician to find the leak source, replace the failed seal, hose, or part, and confirm the anti-flood float resets. When the fix calls for trained service, book a visit through our scheduling page and an experienced, qualified technician will diagnose and repair it.
Prevention and care
Regular care keeps this condition from returning on your Viking Dishwasher. Keep filters, vents, seals, and the condenser, exhaust, or burner path clean, avoid overloading or blocking airflow, check that doors and seals close cleanly, and follow the Viking maintenance guidance for your model. Because this unit relies on electronic control, protect it with a stable, correctly rated power supply and have any built-in installation done to Viking specification so the control never sees an out-of-range condition. If a code appears, note exactly what was shown before you reset the appliance — that record helps the technician reach an accurate diagnosis and avoid replacing parts unnecessarily. Where stored food or wine, a sealed refrigerant system, gas, water on the floor, or a safety lockout is involved, treat the condition as a reason to act quickly rather than wait.
