Sunbeam EM7000 Steam Wand Issues
I have owned a Sunbeam EM7000 for a few years now and all of a sudden after shutting off the steam it continues to flow out of the wand for about 10 seconds before the steam stops. I would appreciate any advice regarding this problem.
Thereís possibly a little bit of scale stuck inside the valve, or it wonít close properly for some other reason. It can be fixed, but you need to get inside the machine. Thatís something you can do yourself if youíre so inclined. If youíre not particularly handy youíll need to take it in somewhere for repair.

Either way youíll probably need to get the valve out and open it up.
Thanks LeroyC for your advice. I have done a descale and checked tip on end of steam wand, however problem still exists. Whilst the steam does shut off, it takes approx 10-15 seconds after the valve is shut off. It now appears that the time to shut off seems to be increasing. I am fairy handy and would like to check o rings in steam valve. Is it a big job to get at the steam wand valve to check the o rings as you suggest.

Itís not a small job as you need to take the covers off. Itís doable, but youíll need the right tools.

Slightly loosen the steam tap then use a 13mm open end spanner to loosen the retaining nut. You can unscrew the lot.
If the o-rings are in decent shape, relubricate them and the contact areas of the shaft with food grade high temp grease. Inox MX6 or Molykote 111 work well. If the o-rings are in poor condition, you can replace them with silicone o-rings as found in other machines for sealing the water tubes.
Readjusting the end stop of the tap actuator should allow you to get the steam to shut off immediately, If not, there's not much else you can do. Some EM7000's just do this regardless.

So i took t back and asked them to look at it under repair warranty.
2nd time round they replaced the valve... but it didnt fix the problem (did they actually test it ??)
Anyway I was of the option that the pump is being switched off fine, BUT the value is only being closed 95% , so it takes 10 seconds for the residual pressure to dissipate.
In my search i came across this post that explains the issue exactly, buti am a few steps ahead with a new switch & Value ( PS I have the old value)
And here at teh bottom of this thread i find mention of Adjusting the Tap !! But I cant seem to find any instructions on how to do this? If they are posted somewhere can you direct me - alternatively can you explain how to do it please?
The instructions for removal of the tap is written directly above the quote you have highlighted.

Another point, sometimes it's better to have the steam not shut off immediately. This ensures that the steam wand is cleared and also reduces the strain of steam back-pressure on the steam pump . The pump does have a relief valve to dissipate this pressure but I've seen them be temperamental in the past so I try to just avoid the back-pressure if possible.
