800 Series SHP78CM5N: Bosch groups E8000 and a flashing Clean indication with the door-sensor circuit, not ordinary end-of-cycle Clean status. Remove only visible rack obstructions, close the door, reset for 30 seconds once and request service if the indication returns. First preserve the exact display, timing and operating state: a similar-looking code in another appliance category can mean something else. Cancel the cycle, isolate power, close the water valve and let the tub cool. Wear gloves near filters because hidden glass may be present; do not tilt a built-in unit. After the documented check, use the result to separate a temporary condition from a fault that needs authorised service.
Models covered
Safety first
- Cancel the cycle, isolate power, close the water valve and let the tub cool. Wear gloves near filters because hidden glass may be present; do not tilt a built-in unit.
What the symptom may indicate
Checks in the right order
- Record the evidence
Photograph or write down “E8000 or flashing Clean light door-sensor circuit” before resetting anything.
- Make the appliance safe
Cancel the cycle, isolate power, close the water valve and let the tub cool. Wear gloves near filters because hidden glass may be present; do not tilt a built-in unit.
- Apply the official user check
Remove only visible rack obstructions, close the door, reset for 30 seconds once and request service if the indication returns.
- Decide after one test
If the exact symptom clears, monitor one normal use. If it returns, preserve the code and contact the manufacturer instead of guessing a part.
Stop and get qualified help when
- Stop for active leaking, water in the base, uncontrolled filling, burning smell or a heat, motor or control code that returns after one reset.
Next step
Repair, replace a part, or arrange a diagnosis?
Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.
Resolve it without buying anything
Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.
Replace only the confirmed part
If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.
This guide does not identify a replacement part. Do not order a generic component from the symptom alone.
Arrange a diagnosis before replacing the appliance
Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
