    Agreed...I usually use filtered water.

    Look up how to service the E61 Grouphead and Brew Path / Valves.
    Suggest replacement of seals and Lubricate all moving parts (E61 activation Cams)
    Use a food grade silicon lube.
    All are available from Antony at Casa Espresso ( who was good enough to offer help earlier) or other sponsors here.
    Yes I realise your somewhere in Europe (. maybe Switzerland) - but the parts I refer to are light, freight may be minimal AND your most likely to get the right Parts First time.

    The service / clean up / repair work you do know will pay back in spades once your pulling Consistent shots again and again.
    Good Luck

    Thanks EA - agree totally with your service suggestions and do not intend using the machine until I have completed a service of the E61 grouphead. Thanks also for your suggestions re Casa Expresso as a possible parts source. A back flush has removed quite a bit of stuff and the E61 mushroom did have a bit of scale which I have removed.

    Finding a replacement water reservoir was a bit of an initial challenge. The original T41 reservoir is no longer available, and those from later model Vivis will not fit apparently. It then occurred to me that the reservoir from my Rancilio Silvia might physically fit the space - which it does. These are readily available, and with the addition of another slit cut down the side (to align with the existing hole in the case for the pump lines) it should do the trick.

    Thanks for the tip Yelta. To date I have used a product from Puly which seems to work well - did not know that you could use Napisan.

    Soak your shower screen in some of that, as well as everything else that has coffee oils on. The shower screen will come up like new. Just mix some up in warm water and soak any bits that look like your shower screen.

    I backflush and the stuff that ends up in the drip tray, i utilize to soak anything that needs extra love. I have a brass wire brush that is pretty good for metal bits.

    Shower screen removal - bike tyre levers work well

    Shower screen was really stuck. As per suggestions posted elsewhere I tried both a screwdriver and a spoon without much luck (didn't have a paint tin lid removal tool handy as per another suggestion I saw).

    I didn't really want to use something metal for risk of scratching...and then I thought I wonder if bicycle tyre levers might work?

    First (cheaper) set flexed too much, but better quality (Park Tools) set (blue ones in photo below) did the trick. Gasket was not too bad but as expected shower screen is pretty gummed up - will replace both...

    Virtual coffee!

    Agreed...but a photo of the first decent cup once the machine is going properly might have to suffice (I am a long way from Perth unfortunately ;-)

    I suggested running it in the frame. But you would have had to pull it to fix the motor anyway.

    I have made one of those test leads, but 240v scares the crap out of me, and i havent used it.
    I made the lead in order to descale steam side of my 6910, without the thermoblock being switched on.

    It lives!

    As per Jackster's suggestion I removed the water pump and lines and tested it external to the unit. Did not work at first so dismantled, reassembled and tested again - success!

    Reinstalled old pump in machine, filled boiler and tested steam, hot water and group - all appear to be operating as expected (not bad for a 50 CHF e.g. $67 purchase!). Next steps install new pump (with better mounts), replace group gasket, shower screen (looks pretty gummy), check e61 seals etc.

    Thanks everyone for your help.
