Our temp rises to top heat when steam wand switch is in down position. We have to continually let off steam to get temp down to pull shots.

Hi
Sounds like you have a block in the steam wand
Use a small needle to clean the tip

You should descale the machine, as you may have a blockage in the steam tap.
When descaling make sure that the descaled water goes through the steam wand as well as the group. JURA descaling tablets

You posted this in the TELESCOPE topic.

The wand can leak if the rocker switch is not in the UP position.

In MIDDLE position it will try to deliver hot water.

In DOWN position it will try to deliver steam.

The thermoblock in this unit is actually a 3-way valve, of which two positions route water from the boiler directly to the wand. The 3rd position (UP) routes hot water (but not steam) from the boiler to the group head.

Try holding the switch in the UP position by hand when making coffee. If the machine still pushes water through the wand then you will have to replace the switch inside the machine that is activated by the rocker, or the valve it operates.

Please let me know how it goes.

I HAD the same problem. I fixed it for 50 cents. It takes the removal of 4 screws (2 phillips on top, 2 long standard on bottom by the group) to remove the top to access the steam wand valve. Once the the top (and the chrome bezel) is removed, then screw out the valve counterclockwise buy ALL THE WAY until it comes out. There are 2 O-rings on the stem of the valve that wear out, Cut these off with a sharp knife, go to your local hardware store, buy 2 new ones for 50 cents, install new O-rings, and reverse the disassembly procedure. Voila, no more leaky steam valve!

Try using the milk clamp on the tube going into the milk.Tightening it will make your milk hotter.
Your steam wand however, is a different problem.
First, check in the programming that the steam temp. is 125 celcius.
If it is, and none of the tubes from the steam wand to the boiler valve are blocked, your boiler temp. sensor may be faulty, in which case, you will need to replace that.

Try this from another post. It should help.

The steam wand began to seriously leak but a call to Starbucks Customer Service line and I was talked through how to adjust it so that the leaking stopped. It requires taking off the top/back panel of the machine (6 philips screws) then using a small allen key (1.5 mm I believe) to loosen and adjust a plastic oblong donut-shaped thing (a "cam" actually) on the shaft of the steam knob... no more drips.
The key to prevent dripping is to open the steam knob without putting pressure on it when it gets to the full-open stop position. Cranking it too hard when it comes to a stop in the full-open position will slowly move the cam out of position. Then the shaft doesn't fully seat inside the machine anymore and won't fully shut off the water to the steam wand. Then, no matter how hard you crank the knob in the shut-off position it will still drip. The purpose of the cam is to stop the knob from complete unscrewing and it also turns the pump on and off for the steam wand. The cam adjustment is very small but completely solves the dripping problem. Seeing inside the machine made me realize how easy it would be to repair problems as long as I can get the parts from Starbucks or perhaps Saeco.

I have just had a similar problem. Water no longer moves through the steam wand when I try to prime it. Instead, water shoots through the shot handle (or screen if handle is not in).

One thing I did notice is that the dial for the steam wand unscrewed too far and basically popped out. I screwed it back in and the water did not ever come out of the wand again. I took the top lid plate off and unscrewed the wand dial and removed it. I put it back and noticed that there is a little metal spring switch underneath that I assume turns the wand pump on.

Attached to the dial is a plastic sleeve with a flat side. When the dial is turned, this sleeve should turn the switch on. I noticed though that the sleeve is creeping up the shaft towards the dial head which makes it miss the spring switch.

I don't know what kept the sleeve in place before. Probably a plastic stop that has been worn away from use. There is an allen screw in the sleeve, but tightening it doesn't seem to keep it in place. Perhaps inserting a spring in between the dial and the sleeve would work, but the sleeve cannot be taken off to do this. No other answers right now. My wife is not happy the lattes have dried up.

I have had this machine for four years now, and it is FAB!!! it does have an extra step to it- after you put in coffee and add water to the reservoir, you DO need to prime the pump. So here's what you have to do:

-Fill the reservoir with MORE water then you think you will need, fill the coffee filter with the standard amount of finely ground bean.
-Turn the machine to "on," making sure the "steam" switch and valve (knob) are off.
-Wait till the green "ready" light comes on, then put an empty cup under the steam wand and turn the valve on (the steam switch is still in the off position). Hot water will come out of the steam wand, allow it to flow until the "ready" light blinks off. Discard this.
-close the steam valve, stopping the flow of water.
-turn the "steam" switch into the on position, wait for ready light to come on again.
-put your milk container under the steam wand and froth to your heart's content (this machine makes GREAT frothed milk and you should use a large enough milk container to allow for that! *smile*)
-when you have finished with the frothing, close the valve and flick the "steam" switch back into the off position. You are now ready to make your espresso.
-push either of the two buttons, ie one or two cups, and the espresso will start to flow. There is a way to set the length of time for each of the two buttons, but I have had mine set perfectly for so long i don't know how to do it any more. Sorry!

This has been the best machine I've ever used, and has lasted me for years. I heartily recommend it!

As the espresso is being made, you can steam the milk by opening the valve that goes to the wand. (sometimes there is a "switch")
To steam milk:
-Fill pitcher (or whichever container you want) with milk e**ugh for about 2/3 of your cup. A thermometer would be helpful.
-Place pitcher under the wand and lift it so that only 1/2 inch is under the surface of the milk.
-Open the steam valve. The milk will expand as it heats. Lower the pitcher to maintain the 1/2 inch depth. You should hear a "shushing" sound and have ** splattering.
-When milk is about 150 F (or preferred temp), close the steam valve and wipe the wand with a damp towel or else themilk will cake on the wand.

Good Luck
