    Re: 6910 leaking around group. Advice needed from wise heads.

    Firstly, thanks for the answers AM.  You truly are a wealth of knowledge on the 6910 and Im sure all of the apprentice 6910 baristas appreciate your posts on here as much as I do.  

    Also, ta to Black Gold for letting me in on this convo.  I hope your warranty claim went well.  Im glad you enjoyed my coffee explosion story.  I had tears in my eyes too...  well, nearly.  It was bloody funny.

    Black Gold- Have you used the cleaning tool to poke through the tiny single hole in the dual floor baskets! My single shot dual floor was poorly manufactured and mostly blocked out of the box!! I used a pin to open it up before the tool would even come close to going in the hole.

    If you opened it up then bin it...

    It is a specific size and has a steep screw pitch...

    Any change to that an bin it...  
    I may have phrased that wrong.  My single dual floor basket seemed to act as a blank when I tried to do a sweet spot test with it. Hardly any water coming through it.

    I tried to poke the cleaning tool in the hole and it seemed blocked. I used a needle to see if there was any hole at all.  The cleaning tool then finally snapped through and is still a snug fit.

    I get the same sweet spot using either of the pressurised baskets.  I may have damaged it, but never plan on using it again anyway.  The bins probably the best spot for it!!

    For the record, I seem to have solved my leakage issues.  It was a combination of slight overdosing and being a pussy when twisting the handle on....  Meow!  I go just past 6 oclock now.

    One other thing I notced, is when using the same dose/grind but only tamping very lightly....  meow! again, the machine would nearly choke and leak.  If I did everything the same but tamped harder, so the puck was at the correct height ie just clear of the shower screen (re-did the 5cent test) the shot would pull correctly.

    Its hard to make yourself tamp firmer when you are nearly choking the machine.

    I have found I now need to go one notch finer grind aswell as the firmer tamp now I have the correct puck height (dose/tamp). So go back and check that 5cent test if youre having some choke/leaks. Just thought that this may help some people.

      Great feedback... But I will leave it to you to spout the truth...

      Well done..

      See the numbers are a Guide... But the shot will be affected by how you use them or not... 2 + 2 = 5

      The reason for the choking is that when the puck is forced onto teh shower screen your applying another tamp and at a lot higher forces and leaving no room to expand..

      Damm... Now ya converted... Next thing you will need to go off and be saved

      PS. The same process applies to all commercial machines; so it is not a skill, that is not transferable..

                Ive had a similar thing happening recently. No change to good coffees that I have been making with my 6910 for about 7 months. About 2 weeks ago, started getting some dripping at the back of the GH. Thought "hmm, a bit early for a seal break - oh well. Bought a new one. The old one looks fine. Replaced it - still leaking. Its clean, and Ive not changed anything else...

                Interesting read here. Thanks all involved. Looks like I should take my machine in...

                  Depending on use... 6 months can be a good time to replace...

                  You should be inspecting at your usual 2 or 3 month head cleaning / chemical backflush and when you pull the shower screens out ?


                  Let us know what happens..

                    Current status is awaiting opportunity to take machine to service agent in Melbourne for warranty repair.

                    Will let you know what they find, if I can find that out.

                      I did ANOTHER good hea clean yesterday and paid extra special attention to wiping around the head with the shower screen off. Then I actually put the old (still looking intact) seal in... Wah-laa! Seems to not be leaking. Hope it holds up

                            I hope I can resurrect this thread. I need more help!!

                            After continual small leaking, I took my machine to the Sunbeam service centre in Adelaide. Of course it sat on the bench waiting for three weeks and when they finally looked at it they could not find a problem!!!

                            I have been told that they put a stopper in the basket and it did not leak at all. I picked it up, took it home and guess what... It still freaking leaks!!!

                            I have no idea what to do?!? Could it be a fault with the basket Im using? It is just the standard, single floor, double sized basket.

                            I dont understand why it will leak when I use it, but when it is tested with maximal pressure it does not?!

                            Please help

                              Ring Sunbeam first.
                              Tell them what happened.
                              Tell them you are taking it back.
                              Take it back and demand to show the tech that it leaks or that he show you it doesnt (immediately not in 3 more weeks).

                              All this is dependent on you using the same handle and basket to show the tech the leak.
                              If hes using a different one to test it then that variable should point to the fault.



                              P.S. Is this an Authorised 6910 repairer?

                                Its an authorised repairer. I think my wife will take it back this week, with our coffee, our handle and our leak! Ill tell her to not leave til they look at it. Such a pain in the ass. The service centre is not close to us at all!
