Only Flow From Brew Head

  1. Remove the pannarello nozzle attachment from the steam wand and test the flow using the hot water function. If flow is restored then the pannarello nozzle needs to be fully disassembled and cleaned and then properly reattached.
  2. 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.
  3. The solenoid valve may be blocked and should be cleaned according to the instructions found here: BABIES-CLASSIC 3-Way Solenoid Cleaning.pdf
