Milk system troubleshooting
Steam wand or milk system is blocked
Milk residue builds quickly, especially in narrow nozzles and removable milk parts. Start with the cleaning routine the manufacturer expects after milk use.
THE PROBLEMSteam output is weak or milk flow is restricted.
Ventori only covers checks that sit within normal user maintenance. If the symptom remains after the correct routine, move to manufacturer or engineer support rather than repeatedly running cleaning products.
First maintenance checks
Rule out the simple causes first.
Work through these in order before repeating a maintenance programme.
