Why is the coffee stream weak in my Bezzera Duo DE?
- F
  Felicia LarsonAug 15, 2025
  If the Bezzera Coffee Maker produces coffee with a weak stream, it might be due to several reasons: * The coffee grind could be too fine. * The coffee in the filter holder might be overly compressed. * There might be too much coffee in the filter holder. For the first three potential issues, adjusting the grind and dosage should resolve the problem. If the group shower is clogged or the pump pressure is low, a technician will need to intervene. If the filter in the filter holder is clogged, try cleaning or replacing it.

  If your Bezzera Coffee Maker dispenses coffee too quickly, it could be due to several factors: * The coffee grind may be too coarse. * The coffee in the filter holder may not be pressed firmly enough. * The dose of coffee in the filter holder may be insufficient. Adjusting the grind and/or dosage of the coffee can resolve the first three issues. However, if the pump pressure is too high, a technician will need to address the issue.

  If the coffee from your Bezzera Coffee Maker is too cold, it could be due to a few reasons: * The filter holders might be cold. If so, keep the filter holder mounted on the group. * The coffee might be ground too finely. If so, adjust the grind. For issues related to a dirty water circuit (scale) or boiler pressure being too low, it's best to call a qualified technician.

  If the coffee from your Bezzera Coffee Maker is too hot, it might be due to: * The boiler pressure being too high. * The machine being covered, which prevents cooling. * The machine being installed in a location without proper air circulation. For high boiler pressure, contact a technician. For issues related to cooling, ensure proper ventilation around the machine.

  If the coffee from your Bezzera Coffee Maker is lukewarm, contact a specialized technician to check the vent valve. Alternatively, opening the steam tap menu (Fig. 01; pos. 9) will cause the boiler pressure to drop to zero, which will then engage the heating element and increase the temperature.
