When to replace steam and water valve parts
Because steam and hot-water valves take constant heat and pressure, so seals and knobs are common wear items, these are parts owners replace regularly. We stock valve bodies, stems, seals and o-rings, knobs and steam/hot-water wands for this model. Typical signs it's time to order include steam or water dripping when the valve is closed, a stiff or seized knob, or weak steam pressure - all fixable at home with the right spare.

Not every part fits every version of this machine. When in doubt, send us your model and serial details and our team will make sure you get a part that fits.
