What this family is
This page profiles the SMS dishwasher family — the sixteen codes in the table below and nothing wider. The sixteen codes cover more than one build generation, so match your own code against the table.
What goes wrong on these models, and where each one is covered
- Dishes come out gritty, filmed or still wet — Grit on both racks is the filter; a dirty lower rack alone is the lower spray arm; wet plastics are rinse aid. Worked through on the cleaning and drying page for this family. — Slug: bosch-bosch-dishwasher-sms-dishwasher-cleaning-performance — Title: Bosch SMS Dishwasher: Does Not Clean or Dry
- Water stands in the bottom of the tub after a cycle — Listen at the drain step: a hum with no movement is a blockage, silence is electrical. Worked through on the will-not-drain page for this family. — Slug: bosch-bosch-dishwasher-sms-dishwasher-drainage-failure — Title: Bosch SMS Dishwasher: Will Not Drain
- Water on the floor around the machine — Foam at the sill is detergent; a wet toe-kick during a cycle is under-tub; an idle puddle is the supply fitting. Worked through on the water-leak page for this family. — Slug: bosch-bosch-dishwasher-sms-dishwasher-water-leak — Title: Bosch SMS Dishwasher: Water Leak
- The machine will not begin a cycle — A dark panel is power; a lit panel that refuses is the latch, a lock or a delay; a dry stall is water. Worked through on the will-not-start page for this family. — Slug: bosch-bosch-dishwasher-sms-dishwasher-wont-start — Title: Bosch SMS Dishwasher: Will Not Start or No Power
The problem classes, in the order they bring these units to a technician
- Dishes come out gritty, filmed or still wet — First across this family: it brings the most of these machines in, and the older codes have had longest to load a filter.
- Water stands in the bottom of the tub after a cycle — Second: glass chips and soil find the sump eventually, and the older codes in the table have had time to collect them.
- The machine will not begin a cycle — Third: latches wear and strikes bend with use, which lifts it above leaks on a family with this age spread.
- Water on the floor around the machine — Last of the four and the most urgent: seals harden with age, and water damage outruns the repair.

Before anything is opened
Safety
Isolate the machine at the breaker before the toe-kick or the door skin is opened; a capacitor can hold a charge after the power is off. Shut the water at the valve under the sink first, and leave the door interlock connected.
What is an owner job on these models, and what is not
Across this family the boundary is the same on every code in the table: anything reachable with the racks out is yours, and anything behind the toe-kick or the door skin is not.
