How to fix it
- Turn off the water inflow to the dishwasher at the supply valve, per Bosch's instructions.
- Tip the dishwasher back ~45 degrees to drain water out of the base pan (place towels).
- Stand it back up — the E15 often clears once the float drops.
- If it returns quickly, find and fix the leak source (pump seal, hose clamp).
