What Does Error E3 Mean?
The E3 error code on your Bauknecht dishwasher indicates a potential drainage issue or a problem with water heating. This may manifest as the dishwasher stopping mid-cycle, failure to heat water properly, or unusual sounds from the pump. Additionally, if your model displays a combined F3/E3 code, it could signal a calibration fault with the Optical Water Indicator (OWI) sensor. Addressing these issues usually involves inspecting or replacing the heating element, temperature sensor, or OWI sensor.
Common Symptoms:
- Dishwasher stops mid‑cycle with E3 displayed.
- Water does not heat properly or temperature not registered.
- With F3/E3 combination, may correlate with drainage/water level sensing issues related to OWI sensor.
Possible Causes
- Heating element or temperature sensor failure/reading fault (medium)
- Optical Water Indicator (OWI) sensor calibration or malfunction (in models showing F3/E3 pattern) (medium)
How to Fix Error E3
DIY Fix Basic checks and reset
- Turn off and unplug the dishwasher for a few minutes, then restart to see if the error clears.
- Ensure the dishwasher has hot water supply from your home tap (set hot water heater to appropriate temperature).
- Check for any obvious blockages in filters and spray arms that could impact circulation.
Technician Only Inspect heating/temperature sensing components
- Measure heating element resistance with a multimeter to check for open/short conditions.
- Test the dishwasher’s temperature sensor (NTC) resistance at known temperatures to confirm response.
- Inspect wiring and connectors to the heating element and sensor for damage or corrosion.
Parts needed: Heating element, Temperature (NTC) sensor, Associated wiring/connectors
Technician Only Clean or replace OWI (optical water indicator) sensor if model uses F3/E3 interpretation
- Disconnect power and remove lower dish racks and filters to access the sump area.
- Locate the OWI sensor beneath the filter assembly and clean any debris or build‑up.
- If cleaning does not resolve the code, replace the OWI sensor with correct part number.
Parts needed: OWI sensor
- If after basic resets and cleaning the error persists.
- If you are not comfortable testing electrical components with a multimeter.
