After the old forum software breaking in a way that we were unable to fix, we've migrated the site to a new platform.

Some elements aren't working as we'd hoped - some avatars didn't survive the transition, and we're still having issues with attachments that weren't added as inline images, but we're hoping to have that all sorted out soon.

em6910 flow rate

edited January 1970 in Espresso Machines
Hi guys,  I've had my em6910 for nearly 12months now and i think everything is going ok.  things recently improved with the purchase of my awesome Pullman tamper but I have a query regarding the flow rate of the water out the shower screen.

I've recently been on holidays staying with another family member who has been using his old em6910 whilst waiting for a replacement dual boiler from breville.  now his em6910 has some minor differences to mine as its quite an early one.  obviously sunbeam did some minor running changes with the model. 

this brings me to my question.  I noticed the water on his, when you flush water through the group head without the handle in, comes out like a shower.  mine on the other hand has 4 distinct spurts (if you imagine 4 holes in a square eg 2 x 2), rather than a shower of water.  i've had the shower screens out to clean them on many occasions so they are clean and well maintained.  is this one of the running changes?  or should mine pour more like a shower?  would this matter if the volume of water coming out is the same? 

we have the same setup, same grinder, same machine and same beans (merlo kenyan) and yet i reckon mine 'blondes' a bit quicker on my machine (this is compared to me using his machine, so same operator).  could the difference in the way they distribute the water have anything to do with it?

coffee still tastes ok but just thought i'd make sure there wasn't a problem as my machine nears the end of its warranty period.  apparently the later ones are near bullet proof so just making sure.

  • How clean is your inner shower screen?  That's where I'd be looking first... Cleanliness is near to God-shotliness!
  • just adding a bit more to this discussion, my pour is often quite thin looking, but still achieves 25-30ml in 25-28sec give or take, so i don't worry too much about it these days. maintenance gets carried out fairly regularly, in so much as the machine is 15 months old and both shower screens still look almost new, as does group head.  is there a way of checking the flow rate, or if i am able to achieve the recommended shot in about the right time, is it worth worrying about?
