    Single Boiler Steaming ?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all CSers.
    Im the proud new owner of a Lelit combi :) and I have a quick question.
    When steaming on a single boiler there is a chance it can run out of steam and then the boiler kicks back in - right?
    So how do you go about preparing the steam function and then doing some sort of purging or hot water running to get the boiler going again and hence keeping the boiler up while youre steaming?

    I dont know how clear I have made this and hopefully I havent missed another thread which can answer this for me or at least discuss it.

    Thanks :)

    i think on some machines like yours, what you can try to do is this:
    flick on the steam switch, and wait with a close ear nearby. see if you can hear any click when the thermostat turns off (meaning it has reached the set temp for steaming).
    what you can try doing to increase steam ability is to time that moment when the thermostat clicks off, and then several seconds beforehand, open your steam wand to steam your milk. what you are trying to do there is to cheat the boiler by not allowing it to reach the cutoff temp and the thermostat will keep on working, which should help.

    hope that helps

    I am a heathen... I simply heat the milk in a microwave! But, Im interested in the Lelit Combi, how are you finding it?

    Thank you all for the information!

    I have a deLonghi EC410, (received second hand without a manual). When the boiler reaches "steaming temperature", a light turns on to indicate that the machine is ready. Waiting for the "OK" light to come on has usually meant that it takes several attempts to steam milk successfully, (the light goes out and the pressure drops...stop and wait for the light to come on again...repeat).

    After the information here and on the CoffeeGeek forum, I waited till I could hear the water in the boiler boiling, and started steaming the milk, (before the light came on). For the first time ever, I had sufficient pressure to steam the milk in one run! Now all I have to do is work on my technique...

    Thanks again for the great info! :D

    Re: Single Boiler Steaming ?

    Interesting reading - I have not had too much trouble with creating micro foam - MOST OF THE TIME!!

    However I have had inconsistency as well, I always purge the steam wand to get rid of any water, turning the steam function on and off a few times seems to do the trick. I just checked my machine and as soon as I turn the steam function on the light goes on immediately.

    My inconsistency is clearly an operator issue. I tilt the jug, (the one that came with the machine) about 30-40 degrees, and point the wand at the wall of the jug about 5cm from the wall, as the milk is stretched I bring the jug up to vertical. In the past I have often stretched way past 40 degrees, but not higher than 50 degrees.

    I am not sure what temp gives the best microfoam, I am not sure I can get enough quantity at the low temp of 37 degrees. Some say this is best for soft microfoam, and that at this temp the wand should be placed lower in the jug and in the middle.

    I guess more practise required here. :)
