What Does Error E19 Mean?
The Bosch refrigerator error E19 signals a malfunction related to the ice maker or auxiliary systems, potentially causing erratic temperature readings and impaired cooling performance. This may involve issues with the ice maker subsystem or the auxiliary lighting circuit. Prompt attention is necessary to ensure optimal functionality and prevent further complications.
Common Symptoms:
- Display of code E19 on refrigerator panel
- Possible loss of ice maker function
- Potential auxiliary/light circuit malfunction
Possible Causes
- Ice maker subsystem internal configuration/memory fault (community pattern) (low)
- Auxiliary output / interior lighting circuit fault (community pattern) (low)
How to Fix Error E19
DIY Fix Basic checks and soft reset
- Turn off refrigerator power at breaker or unplug for 30 seconds, then restore power to clear transient errors.
- Check if ice maker or auxiliary subsystems (lights, displays) respond or reset after power cycle.
Technician Only Inspect ice maker and control circuits
- Access ice maker control board and connectors and inspect for loose wiring, corrosion, or visible damage.
- Test the EEPROM/configuration memory and control board functionality pertaining to the ice maker/auxiliary circuits.
- Verify auxiliary outputs such as door interior lighting and related wiring harnesses for shorts or faults.
Parts needed: Ice maker control board, Wiring harness for auxiliary circuits, EEPROM/configuration module if separate
- If power cycling and basic checks do not clear E19
- If ice maker or auxiliary circuits show electrical faults beyond simple wiring inspection
- If the refrigerator exhibits additional cooling failures beyond the E19 code indication
