The short answer
This page profiles the Bosch SMU-series dishwasher - the models whose number carries the SMU prefix - and routes you to the page for your fault. These share a platform rather than a spec sheet: the controls sit on the face of the door and stay readable with the machine shut, so the panel is the first thing that reports a fault.
Where each fault is answered
- Dishes come out dirty or gritty — A filled filter, jets that have closed up, or a dispenser flap held shut by a tall item. — Slug: bosch-bosch-dishwasher-smu-dishwasher-cleaning-performance-2 — Title: Bosch SMU-series dishwasher leaving dishes dirty: why, in likelihood order
- Water standing above the filter — Anything covering the filter when a cycle ends. A film below it is normal. — Slug: bosch-bosch-dishwasher-smu-dishwasher-drainage-failure-2 — Title: Bosch SMU-series dishwasher not draining: the checks in order
- Water on the floor — At the door it is the seal; a machine draining unasked has found water in its base pan. — Slug: bosch-bosch-dishwasher-smu-dishwasher-water-leak-2 — Title: Bosch SMU-series dishwasher leaking water: finding the real source
- The machine will not start — The door not latching, a lock-out on the panel, or the switch under the sink. — Slug: bosch-bosch-dishwasher-smu-dishwasher-wont-start-2 — Title: Bosch SMU-series dishwasher that will not start: what to rule out first
Problem classes in order
- Dishes come out dirty or gritty — Commonest here: the filter is meant to be rinsed by the owner, and a machine recirculating soil washes as badly as that filter is full. No share is claimed for it.
- Water standing above the filter — Second here: the same filter closes the path the drain pump needs, which is why these two arrive together. No share is claimed for it.
- Water on the floor — Third here: the door is handled most and inspected least, and its seal is all that stands between the tub and the floor. No share is claimed for it.
- The machine will not start — Least common of the set: door, lock-out and supply account for most of these, and almost none end with a part replaced. No share is claimed for it.

Owner fix or service call
The filter, the arms, the dispenser, the door seal and everything under the sink are owner ground here. The line is the tub: anything needing the base plate off or a meter on the pump is a service call.
