Rebuild valves
When properly maintained, the steam and hot water valves have a very long life-span. Since
temperatures in these valves rise up to 125 °C (257 F), the (Viton, Teflon and silicone) sealing parts
inside wear out a bit quicker than in your house-hold taps.
Materials needed
Allen key 5 mm
Adjustable spanner
Spanner 10 mm, 20 mm, 22 mm, 26 mm
Rag
Heat resistant, food safe, grease
Replacement O-rings and disks (for both valves: 4x Viton disk, 2x plunger with Viton seal, 2x
Teflon O-ring in between valve and base, 2x (red) silicone O-ring in wand, 2x Teflon O-ring under
conical nut, 4x Viton O-ring on wand-plunger)
Figure M 16a (left). Unscrew self-retaining nut with spanner 10 mm while retaining knob.
Figure M 16b (right). Remove valve end nut from valve, use rag to prevent scratching. Normally, the
valve knob would be removed already..
Procedure steam valve
1. Turn machine off.
2. Open steam valve until no more steam escapes the machine. This is to release pressure from hot
water/steam boiler, keep valve open.
3. Remove nut with 10 mm spanner (see Figure M 16a).
4. Remove steam wand: twist off conical nut with spanner 22 mm (see Figure M 11).
5. Put rag over valve end nut (see Figure M 16b) to protect chrome, loosen with 26 mm spanner, do
not remove the nut completely at this moment.
6. Remove the two Allen bolts (5 mm), a spring will push the valve from its base (the base of the
valve will remain on the Mirage). Be careful not to lose any parts. The Teflon O-ring will probably
remain in the valve, pry out gently.
7. Now remove valve end nut.
8. Use valve knob on square end of shaft to remove shaft from valve.
Caution
!
The threads on the shaft are counter-clockwise.
