E15 Water leak detected (Aquastop)
What this code means
A float switch in the base pan has sensed standing water and locked the unit to pump it out. "Aquastop" is Bosch's name for this leak-protection feature, not a separate code.
Most likely causes
- Small leak from a door gasket or hose connection
- Oversudsing from using regular dish soap instead of dishwasher detergent
- Cracked or loose spray arm seal
What to try first
Tilt the dishwasher back carefully and check under it for standing water; run the drain/cancel cycle to clear the base pan, then dry it with a towel.
Good news: this one is often fixable without a service call. If it persists after the steps above, have it looked at.
