Bosch models: Bosch dishwashers have a three-stage filter: coarse screen, flat micro-filter, and cylindrical fine filter under the lower spray arm. Remove and clean all three together. Bosch drains actively using a pump — any standing water in the sump at mid-cycle is a blockage indicator, not normal residual water.
Common causes
- Door seal worn or cracked
- Spray arm hitting a tall item and directing water upward onto the door
- Circulation pump seal leaking
- Inlet valve dripping when closed
Step-by-step fix
- Check the door seal for visible cracks or displaced sections.
- Check that no items in the upper basket are above the top of the door opening.
- Run a cycle and use a flashlight to observe underneath during operation.
- Identify the leak source before running again.
