What Does Error E1 Mean?
The Blomberg Dishwasher E1 error code indicates a problem with the water inlet valve or drainage system. This may prevent the dishwasher from filling with water, often accompanied by unusual sounds or water remaining in the bottom of the appliance. Key issues include a blocked water supply, a malfunctioning drain pump, or activation of the flood sensor due to water accumulation in the base.
Common Symptoms:
- Dishwasher fails to fill with water and does not start normal cycle prior to showing E1.
- Water remains at bottom and machine stops.
- Drainage issues, blocked pump/hoses reported when E1 appears.
Possible Causes
- Water supply/inlet fault (no water reaching dishwasher within expected time) (medium)
- Drainage or flood detection activation (blocked drainage or water in base triggering flood sensor) (medium)
