What this steam knob assembly does
The Victoria Arduino steam knob assembly (98060000000302) is the control knob that operates the steam valve on your espresso machine, letting you open and close the steam flow used for frothing milk or heating water. It sits directly on the valve stem, giving you the grip and leverage needed to turn the valve smoothly.
Signs it needs replacing
Over time, constant turning and exposure to heat and moisture can wear the knob's grip, loosen its fit on the valve stem, or crack its surface. A knob that feels loose, slips when turned, or no longer sits securely can make it difficult to control steam output precisely, and should be replaced to keep the valve working reliably.
