How do I fix Bosch Dishwasher error code E15?

Step 1: Tilt the dishwasher to drain the base. With power off at the breaker, carefully tilt the dishwasher forward about 45 degrees. Water will drain from the base pan. Place towels down. Let it sit tilted for 1–2 minutes. Step 2: Allow the base to dry. After draining, leave the dishwasher upright with the door open for several hours to allow any remaining moisture to evaporate from the base. Step 3: Check the door seal. Run your fingers along the full perimeter of the rubber door gasket. Look for cracks, tears, or sections that have pulled away from the channel. Replace if damaged. Step 4: Check for oversudsing. If you used too much detergent, suds overflow into the base. Use only recommended dishwasher detergent — 1 tablespoon maximum. Step 5: Inspect internal hose connections. If the above don't apply, access the inside of the door panel and check the water inlet, circulation, and drain hoses for cracks or loose connections.
