Bosch SHX78CM5N (800 Series) Repair Guide
Bosch’s 800 Series with CrystalDry, which uses a mineral called zeolite to convert moisture into heat and genuinely dry plastics — the one thing condensation drying has always struggled with. At 42 dB it is also among the quietest dishwashers sold.
Common problems & typical repair costs
| Problem | Likely cause | Typical fix | OEM part # | Typical cost |
|---|---|---|---|---|
| Water standing in the sump at cycle end | Drain path blocked — filter, pump or high loop | Clear the full drain path including the air gap | — | $150–$320 |
| E15 error and the drain pump running constantly | Leak protection tripped by water in the base pan | Find and reseal the leak; dry the pan and reset | — | $200–$450 |
| Dishes not drying as well as when new | Rinse aid empty, or the CrystalDry zeolite system degrading | Refill rinse aid first; diagnose the drying system if it persists | — | $0–$400 |
| Poor cleaning | Filter clogged or spray arms blocked | Clean filter and spray arm jets | — | $0–$180 |
| Will not start, no lights | Door latch switch or power supply fault | Replace latch assembly; check supply | — | $150–$340 |
Costs are national averages for professional repair (parts + labor). See the linked cost guides below for full breakdowns.
Error codes
| Code | What it means |
|---|---|
| E15 | Water in the base pan — leak protection active |
| E24 | Drain blocked |
| E22 | Filter blocked |
| E09 | Heating element fault |
| E01 | Control board fault |
Tech notes
The constantly running drain pump on an E15 is the machine protecting the kitchen floor, not a pump fault. Tilt the unit forward to drain the base pan, then find the actual leak — replacing the pump on an E15 fixes nothing.
