What this family is
The codes in the table below are the whole of the SGX family: five built-in dishwashers sold under this brand. They sit close together in build, so what follows holds across all of them.
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-sgx-dishwasher-cleaning-performance — Title: Bosch SGX 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-sgx-dishwasher-drainage-failure — Title: Bosch SGX 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-sgx-dishwasher-water-leak — Title: Bosch SGX 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-sgx-dishwasher-wont-start — Title: Bosch SGX 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: it arrives most often, and on a narrow family it is usually setup — rinse aid, loading, detergent — not wear.
- The machine will not begin a cycle — Second on a family this narrow: most of it is a setting or a door rather than a worn part.
- Water stands in the bottom of the tub after a cycle — Ranked here, and on a young family it skews to installation — a knockout plug left in, or a hose with no high loop.
- Water on the floor around the machine — Last by frequency, first by urgency: rarer on young machines, and the one fault where waiting costs more than the repair.
Models in the SGX family — Some codes here are pinned to a single build and the rest are patterns covering several, so match the longest entry that fits the tag inside your door frame.

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
Everything reachable with the racks out is an owner job across this family: the filter, both spray arms, the dispensers, the door seal and the connections under the sink.
