E15 appears and the dishwasher will not start; often associated with water in the base pan (similar to E05 on some models).

Safety first: Turn off power and water. Avoid tipping the unit if water may spill onto electrical components.

• Remove toe-kick and inspect base: Look for standing water and the float or sensor in the base pan. Dry all water with towels or a wet/dry vacuum.
• Identify leak source: Run a short fill cycle while observing the base (restore power briefly). Watch for drips from the inlet valve, hoses, pump, or sump. Turn power off again before touching anything wet.
• Correct over-sudsing: If you see excessive foam, you may be using non-dishwasher detergent or too much rinse aid. Run a rinse cycle with a small amount of cooking oil to break down suds.
• Repair leaks: Tighten hose clamps, replace cracked hoses, or install a new Viking sump or pump seal as needed.
• Reset sensor: Once dry and repaired, the float or sensor should reset automatically. Run a full cycle to confirm no further leaks.
