Bosch 00427903 Dishwasher Micro Filter

Dishwasher Micro Filter – Bosch

The dishwasher micro filter is part of the multi-stage filtration system at the bottom of your Bosch dishwasher. It catches fine food particles and debris during wash and drain cycles, preventing them from being recirculated onto dishes or clogging the drain pump. When the micro filter becomes damaged or clogged beyond cleaning, wash performance drops and dishes may come out with grit or residue. This direct-replacement micro filter restores proper fine-particle filtration.
