Subject: My Giemme control box fix
|
The following is based on my own experience. I will not hold any
responsible If you try any of these suggestions and break your
machine, this procedure is at your own risk.
My Isomac Tea get unstable a few months ago and I found it was the
Giemme control box's problem. It will stop working after the machine
heat up for about 20 minutes. Replaced the Giemme and everything been
fine since.
So I think of repair the broken giemme then I will have a backup
component. Open the Giemme box and I found it's pretty simple. I
suspect the onboard 115v~18V transformer can't work properly after get
warm. Can't find a replacement locally( It's a eichhoff product), so I
soldered the transformer off the board and use wires to connect to
board. put the transformer out of the Tea. Now the Giemme back to
life. The transformer only get around 30C at room tempature after 2
hours work.
Cost: 30 minutes and a few high temp wires.
Don't forget to unplug the machine and let the machine cool down
before you open the case to do anything. Wrap the wire connection with
tape.

Paul, those small elec. shops in beijing can customize transformer or
heating elements for you. I just don't have time to buy a new
transformer so I use external transformer. :)

The transformer is usually the cuplrit or the relays. The problem is
finding a transformer to fit exactly. I've never found one here in
hong kong but the relays are standard.

Thanks, it IS over priced. In fact, I can get everything replaced on
that board for 10 RMB (around 1 euro or 1.5USD).

YOu have an Isomac? :(
you are right, it is UNDER the boiler. You'd think soemthing as
simple as one of these would be more reliable.

You're probably right about the transformer - I recall this being the
problem in the Livias that suffered from bad brain boxes.

Great job! very ingenious. maybe mount the xformer inside -- in the
bottom of the machine, where it is MUCH cooler.
those so-called "brain boxes" are WAY overpriced, for what is in them
and what they do!

On my Isomac, the Giemme IS mounted on the bottom of the machine. Apparently, it
is not cool enough down there. Dan
