Error code overview
E24 on a La Cornue dishwasher: record the exact display, model, and ZIP. Not a universal fault map. In a in-law kitchen, a bottom rack was in play when the door was just latched; keep E24 with this dishwasher rating plate.
Model compatibility: La Cornue reuses codes across series and model years, so E24 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
