Bosch 300 Series SHE53C8xN (SHE53C85N / 86N / 82N) PureDry dishwasher: quick sheet
Covers: Bosch 300 Series 24-inch built-under SHE53C8*N: SHE53C85N (stainless anti-fingerprint), SHE53C86N (black) and SHE53C82N (white). Front display with pocket handle. Current 300 generation with Home Connect Wi-Fi; years approx. 2022 onward (inferred from listings; no official launch date found). Older 300 Series SHE/SHX models have their own quick sheet. Find the model/serial tag on the tub edge inside the door. Build-date reading from the serial is not stated here (not confirmed by two sources for this family); see the guide find-model-and-serial-number-on-any-appliance.
Mid-line Bosch: 16 place settings, 46 dBA, stainless tub, third rack, PureDry closed condensation drying (no exposed heating element), AquaStop leak protection, Home Connect remote start. No hard food disposer: the manual filter must be cleaned. Faults use the Bosch E-codes (E15 water in base, E24/E25 drain, E09/E21 heat pump, E22 filter). Deeper diagnostics are in the Bosch dishwasher field service manual.
Safety first
- Switch off the circuit (or unplug) and close the water supply before removing the kick plate or pulling the unit.
- Hardwired units: open the junction box only with the breaker off and verified dead.
- Water in the sump may be hot right after a cycle; the heating element stays hot for a while.
- Live-voltage checks at the valve, pump, heater or board are caution work.
- Watch for broken glass in the filter and sump.
- Flood risk: keep towels down and confirm no leaks after reconnecting.
How it works
Tub and racks: stainless tall tub, three racks (third rack standard), RackMatic upper rack with three heights.
Pump and wash: inlet with flow meter and AquaStop hose; a combined circulation pump with built-in heater (the Bosch "heat pump") heats and circulates water through two spray arms; a separate small drain pump empties the sump. Aquasensor reads soil/turbidity. The page also lists SilentPowerDrive and PrecisionWash.
Programs: Heavy, Auto, Normal, Speed 60 and Favorite on the panel, with Sanitize, Extra Dry and Remote Start options; more programs (e.g. Half Load, Machine Care, Rinse) through Home Connect.
Filtration: three-part manual filter (cylinder, fine mesh, micro filter) in the tub floor, no disposer.
Drying: PureDry is closed condensation drying: no outside air, moisture condenses on the cooler tub as dishes cool. Rinse aid is essential.
Leak protection: AquaStop combines a base-pan float switch with a safety valve at the supply end of the inlet hose.
