    To leave on or not to leave on?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi guys, I have just upgraded from sunbeam 6910 to a nuova simonelli oscar (thank you Tony Land), and Ive got to say for starters how happy I am with the new machine :D. My question is, if I am home for the day should I leave it on all day? I am inclined to do so and have today without any worries, I just wondered if its the right thing to do with these machines? I figure itll use less power if I just leave it on and let the boiler cycle to keep it at a steady temp (kinda like your air-con unit) rather than turning it on and off a few times a day and really working hard to get up to temp.
    Your two cents worth is appreciated *:)

    I have an Oscar at the office which gets left on all day. No issues at all with this type of machine. It also encourages you to drink more black gold during the day :)

    Re: To leave on or not to leave on?

    Ha ha yes it does! Thanks I thought I was on the right track. Also how often should I back flush? I normally do it just with water after every session just to clean the old grounds off the group seal (I like it clean and tidy), is this still ok? I know that with some machines it is not recommended to do it all the time but I couldnt find it in the manual anywhere.

    Im not completely au fait with the general arrangement of the internals of the Oscar but given how quickly this style of machine heats up to operating temperature, I dont know why youd want to leave running for hours without use... Its not a commercial machine after all.

    Exposing electrical and electronic devices to high temperatures actually accelerates the deterioration of various intrinsic compounds. The longer this exposure, the greater the accumulated effects. So long as youre aware of this downside, its then up to you whether its worth it or not....

    Most of the boards that our technician has change, or due to the tare and ware of the component or because people leave their machine 24/7

    I can well understand that Renzo.....

    So-called prosumer machines are just NOT designed to be left running 24/7.... Simple as that.

    Only just saw this and the comments above..

    Yep.. On 24/7 for many things is not ideal... While for some items it is teh norm; it is usually about items that draw little current etc.

    Many PCs for example ie. Servers stay on 24/7 and when they are turned off; the power supply usually fails.. Thus a good reason why raid 5 also means extra power supplies. CRTs and LCD monitors are another typical example of a unit that should never be left on 24/7...

    As to the Oscar.. saw two at DiBella a few months back that had cooked and had total melt downs..

    One 24/7 and shoved into a corner in a kitchen with no good air flow.. One even buckled teh whole side panel...

    Some people want that coffee quick in teh morning..

    1: Switch it on and have ya shower and or do other things first first... It will/should be hot enough

    2: Have a timer

    3: Get ya partner to get up first ;D

    And when ya go away for any length of time etc OFF at teh wall. Any short or leak that could trick ya system to come on... Could leave you with a pile of carbon.

    Just ask Coffee2di4 what nearly happened to her roaster.. There is a post some where :D

    2: Have a timer

    Dont think you can put Oscar on a timer (no vacuum breaker)! Only two options left! Or 3 if you include installing a vaccum breaker.

    I think Coffee Parts may have a combination Safety/Anti-Vac Valve in their catalogue somewhere. If its possible to fit this in place of the original Safety Valve, that would overcome the problem having her ready to go when your feet hit the floor in the morning.... ;)

    Re: To leave on or not to leave on?

    Thanks guys, Ill just kick the wife out of bed first from now on hey :P Jokes, The past few mornings ive turned it on before the shower and its right to roll shortly afterwards so I think Ill stick to that method. Would it be a big job installing a vacuum breaker?

    No, it is the last part on this page -

    http://www.dibartoli.com.au/products.asp?cid=47

    There are 2 other 1/4 brass fittings required - if your not that way inclined get a pro to do it or just live with it.

    Better to say.. Looks simple enough :o

    Rather than;

    "famous last words"


    You may not be playing with electricity directly... But you will be in a place that it lives..

    1: Machine off
    2: Cord disconnected from wall socket
    3: Be carefull with what ya do
    4: Get it tested before thinking about connecting it back up.
