You really don't need it. You should have a cloth nearby to clean the wand when you're done. So if for some reason you need to move the wand (and with it's meagre rang of mobility I don't know why you would) be sure to grab it with the cloth because it gets really hot. The rubber thing is just there to avoid lawsuits I'm sure. USA USA!

I initially replaced the o-rings in the pipe/valve assembly. It didn't work for long (not correct size o-rings probably). I then bought a new pipe-valve unit. To replace you need to pry off the stream handle (chromed plastic). It only fits one way on the axle (so take notice when replacing!). Then remove back and side covers (6 screws all at the back). Then remove top (2 screws each side at the front and a couple at the back). Then the front panel should be lose. (Instructions based on a slightly different model)
Mine made better coffee after I fixed the leak! A large portion (perhaps 25%) of the water intended for the coffee went via the steam wand straight into the drip tray, which is not good.
you evidently have an overfill. it can be from 1 solenoid valve,2 electronic level controller,3 level detector wire or 4 if the machine is frozen and it mix waters
You should eliminate them 1 by 1 by this order:
- swich on water supply and open steam knobs. Wait 5 minutes, if water does not leak from pipes continuously you just eliminated $ freezing problem
- leave steam and tea valves open and switch on power of machine, wait until electronics fill few seconds(it is programed to do so each time is switched on)>> wait until you see water leaking from steam pipes, wait them to start giving you steam. If during this you start to see ball it means you succeed to empty the boiler enough to get it in normal. NOW YOU SHOULD control 1 2 and 3
Be patient and wait to rise pressure on the boiler and control the level of water. if the water level rises again you should:
check the detector wire(be sure that the part in water is not insulated with calcium, that the wire and the fitting of the wire are good separated and insulated by teflon insulation and be sure that wire from circuit is good attached to detector wire)
check the solenoid valve: detach the wires to solenoid valve for tank filing, cool down machine to loose all steam and open the fitting attached to exit of solenoid valve , the exit whichsupplies the tank with water. make sure that is still attached to water supply and wait to see if drops are coming from valve IF IT IS SO THAN MECHANICAL PART OF VALVE IS DAMAGED
situation: if we checked 4,1and 3. If they are in order than remains only part 2 controler
controler should be checked in some electronics workshop or replaced with new
For repairing your steam valve you must take it out from boiler(2 screws m6 hold valve to boiler) before unscrew valve you must take of valve plastic knob and steam pipe.
Carefully you take off the seal of valve, seal prevents axle from completely unscrewing.
You unscrew the axle and you go to turner (metal parts shaping machine) there you repair the top of axle, it is like pencil, you only need to sharpen it a bit, than you change 2 o rings in axle, put it in back.
Instead the seal you use now one fitting !/4" and you screw it on to prevent getting out the axle
1: do you pres the switch for steam and wait until it is ready?
2: how long time machine needs to be ready for steaming?
solution 1 =
if you don't press the steam switch on you will have very small amount of steam.
solution 2 = if the machine gets ready only for few seconds to steam, than you must change your steaming thermostat attached in boiler(there are 3 of them:
2 coffee brewing
i hope you fix it soon and enjoy in perfect espresso
there is a rubber sleeve inside, and also a hard plastic olive (like a wedding ring). When tightened, the hard olive compresses the rubber sleeve and it grips.
If you lose the plastic olive, the rubber remains uncompressed and the pannarello will blow off.
The olive is about the size of a wedding ring for a person with a 5mm finger (impossible I know - but the shape is like a tiny black wedding band all the same.).
There should be two rubber pieces inside the threaded collar & cap that help produce a pressure fit onto the wand itself. There is a total of five plastic pieces on my steam wand excluding the wand itself on my Via Venezia by Saeco I purchased a year ago. Sounds to me like you lost one of you rubber gromets! Just my thoughts!
you can find that ring to home depot or any other hardware store.Is called o-ring and if you bring your little part with you someone will help you to find one in home depot.This part is also used in air compression department for airgun atec.
