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

  1. Turn off and unplug the dishwasher for a few minutes, then restart to see if the error clears.
  2. Ensure the dishwasher has hot water supply from your home tap (set hot water heater to appropriate temperature).
  3. Check for any obvious blockages in filters and spray arms that could impact circulation.

Technician Only Inspect heating/temperature sensing components

  1. Measure heating element resistance with a multimeter to check for open/short conditions.
  2. Test the dishwasher’s temperature sensor (NTC) resistance at known temperatures to confirm response.
  3. 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

  1. Disconnect power and remove lower dish racks and filters to access the sump area.
  2. Locate the OWI sensor beneath the filter assembly and clean any debris or build‑up.
  3. If cleaning does not resolve the code, replace the OWI sensor with correct part number.

Parts needed: OWI sensor

🛑 When to Call a Pro:
  • If after basic resets and cleaning the error persists.
  • If you are not comfortable testing electrical components with a multimeter.
