Solution to an overheating Cremina (or, lazy and forgetful Cremina owner)

Postby mattwells on Wed Apr 09, 2008 9:05 am

Okay, so having done this for the umpteenth time, I am looking for some ideas.

My problem is that every time I turn on my Cremina, I walk away to let it warm up. Some time later after finding some distraction (often an hour or so), I remember that I was warming up the espresso machine...which is now too hot to pull a shot.

My thought is that the wiring to the cremina can't be very complex. I am guessing/hoping that I could splice in something that gives an audible beep/buzz/etc. when the heater clicks off. I am usually in the same room as the machine, so I would hear that, but am not paying enough attention to see the light switch off.

Has anyone done anything like this? What do you guys think?

Thanks,
/mw

Ridiculous!

If you really cannot deal with this, then buy yourself a kitchen timer and set it for ten minutes.

Hmmm, sounds as if this is something that could be done. I am sure that a beeper or buzzer could be wired into the same circuit as the pressurestat so that when it kicked the heating element off the beeper would sound. Of course that means that every time the pressurestat turned off the heating element the beeper would sound. If that is not a problem then yes it is feasible. This is something that you could mount inside the unit clear from the boiler I am sure.
Others for ideas on this little project...? That could be something (another bell or whistle) that I put into my 'C Lever'... 8)

Not only is this still ridiculous, if you don't have the ability to design a circuit that only beeps once, then you have no business dealing with potentially lethal electricity.

Bob,
This is simply a person who is seeking an idea. This is not earth shattering stuff. If he wants to modify his Cremina it is his to do so with. You can leave yours just as it is... I am simply attempting to help him with possible ideas.
I think it is possible and quite frankly should be something that Olympia puts into their product. Stoves, microwave ovens, computers coffee makers and many other appliances have them. Why shouldn't Olympia come out of the stone age and offer a 20th century convenience as others have done? There are many who have the ability to do this sort of project. The original question was "Is this feasible" not, "I am going to personally do this."
Yes this is feasible and would be a convenience to many... JMHO... :D

Wow, what happened to the helpful, DIY-overkill HB that I was used to?

I am thinking that it will be a pretty easy thing to do, and will probably try it out. I will post if/when I get around to it. Just thought I would share my experience (sorry if I offended the Olympia purists around here).

You certainly have not offended me... I think you have come up with something that is a great convenience. :D Others that have any experience or expertise to help with the idea? Parts sourcing... other ideas about where and how to wire in...? starry or Mogo may have ideas.

A low-tech solution is a darkroom timer. Used ones of every shape, size, and feature are available on eBay. Be certain to check the max wattage before buying.

I'm wondering if this has more to do with your pressurestat being set too high. Have you checked it?

I often leave the machine on for longer periods without burning shots. If the group feels too hot I simply pull the shot at the bottom of the cycle just before the heating element kicks in.
