How to Resolve Water Flow Issues on the Bezzera DUO DE

Flow Issues

The first place to start with any flow issue is cleaning the machine. Before going through these steps please make sure the machine is cleaned.

No Steam From Wand

  1. Check the brew function on the machine and see if water is able to flow through the machine for this function.
      • If the brew water is not flowing either, refer to this article.
      • If the brew water flows but is not hot, refer to this article.
  2. Check the hot water function of the machine. If you are able to draw hot water then the steam boiler must be pressurizing and heating, because hot water is expelled from the machine by steam pressure. The steam pressure gauge should also read 1-1.2 Bar to indicate the boiler is pressurized.
      • Remove the tip from the steam wand and test the flow. If flow is restored then the tip needs to be cleaned and reattached.
      • If the flow is still blocked then there may be a blockage in the steam wand itself. Clean the wand by using a pipe brush that has synthetic or plastic bristles; metal bristles can damage the wand. Then soak the wand in a solution of hot water and backflushing powder for ten minutes. Test flow again.
      • If there still isn't flow then there may be a blockage farther back in the steam circuit. The machine may need to be professionally cleaned to remove the blockage.
