Bosch Washing Machine E11 Error Code
Motor overheated during operation
What this error means
E11 logs motor thermal overload—the inverter detected the stator temperature rising faster than allowed, often after repeated start attempts on a jammed drum or an overloaded cycle in a warm laundry room.
How E11 is detected
When E11 appears on a Bosch washing machine, the control board has confirmed that water did not leave the machine within the programmed drain window. On Bosch WAT28400UC, Bosch WGA12400UC, 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 E11 calls are resolved without parts: unplug and leave the door open at least 30 minutes for the motor to cool. 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 E11 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
- Repeated E02-style jams causing the motor to stall and heat
- Very heavy load run back-to-back without cooling time
- Blocked rear ventilation grille trapping motor heat
- Failing motor bearings increasing friction and heat
Step-by-step fixes
- 1Unplug and leave the door open at least 30 minutes for the motor to cool
- 2Remove half the load and run a shorter program at lower spin speed
- 3Vacuum dust from the rear panel vents and ensure two inches clearance to the wall
- 4Retry only after the drum spins freely by hand with no grinding
When to call a technician
E11 on light loads after cooling points to motor bearing or inverter failure rather than user overload.
Affected models
- Bosch WAT28400UC
- Bosch WGA12400UC
- Bosch WAW285H1UC
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use washing machines to prevent E11 from lint and food debris buildup.
- Record when E11 appears in the cycle and whether it clears after a 60-second power reset on your Bosch washing machine—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for E11; Bosch uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting E11; reversed plugs on pumps and valves cause immediate repeat faults.
