Semi automatic coffee machine water intake work is normal, coffee normal, just one open buzzing, I do not know why? Please help everybody, thank you!
Can you be a bit more specific: attack sound head can work normally do coffee, sound so sharp noise is still peaceful hum??
What if it sounds like a shock? As soon as a water comes out
Buzz? Such as unsightly clicks that there may be a problem of the electromagnetic valve spool spring.
