Bosch Dishwasher E07 Error Code
CrystalDry Zeolite fan motor defective
What this error means
E07 means the Zeolite (CrystalDry) fan motor is defective—the fan that moves air through the zeolite chamber for efficient drying did not report speed to the board. Dishes may wash but stay wet at cycle end with E07.
How E07 is detected
When E07 appears on a Bosch dishwasher, the control board has confirmed that water did not leave the machine within the programmed drain window. On Bosch SHPM88Z75N, Bosch SHX878ZD5N, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most E07 calls are resolved without parts: reset breaker thirty seconds once. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If E07 returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Zeolite fan motor bearing seized
- Foreign debris blocking the fan blade in the dry module
- Harness connector loose at the heat pump assembly
- Control board fan driver failure after E12 limescale event
Step-by-step fixes
- 1Reset breaker thirty seconds once
- 2Run a Normal cycle with Extra Dry disabled to test wash-only function
- 3Ensure the dishwasher has adequate side clearance for airflow per install guide
- 4Note whether E07 appears only at dry phase end
When to call a technician
E07 after reset requires Zeolite fan or heat-pump module service on CrystalDry-equipped models.
Affected models
- Bosch SHPM88Z75N
- Bosch SHX878ZD5N
- Bosch SHEM78WH5N
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use dishwashers to prevent E07 from lint and food debris buildup.
- Record when E07 appears in the cycle and whether it clears after a 60-second power reset on your Bosch dishwasher—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for E07; Bosch uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting E07; reversed plugs on pumps and valves cause immediate repeat faults.
