When a Viking dishwasher shows 4-3, treat it as a starting clue — not an automatic parts list. Note when it appeared and whether the appliance still runs safely.

4-3 usually means a sensed fault on this Viking dishwasher. Confirm your manual before buying parts.
Model compatibility: Viking reuses codes across series and model years, so 4-3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
