Subject: Gaggia Dandy or Gaggia Espresso switch light question
|
I have a Gaggia Dandy which looks to be almost identical to the
Espresso, so I think if you know the answer to this regarding an
Espresso, it will answer my question about the Dandy.
Everything looks really good inside this machine, BUT the light does
not come on to indicate when brew OR steam temp has been achieved.
Since it doesn't go on for either, I am assuming the flaw is in the
switch and not in the thermostats. (Seem reasonable?)
Questions are: (Please don't laugh): 1. are there "bulbs" inside
those switches? 2.Are they replaceable? Or will I need a whole new
switch mechanism? 3. Is there a way to diagnose the problem using a
digital multimeter?
Thanks for any help you can give me.

Another diagram -
http://www.sreweb.com/diagrams/dandygaggia.htm
Either that or come off the old existing wires to another bulb.
Possibilities for a custom mount should be fair if you've already
considered a PID and modifying it out of original design. A PID would
need account temperature vacillations associated with a smaller
boiler. Lacking the stability of larger boilers, size and water
routing have a direct effect across a wider temperature range. Not
sure they're intended to work in a low reserve capacity.

In fact, the Espresso switch is quite different from the Dandy switch,
although I had assumed otherwise. And the only problem with your
suggestion, is that the light on the switch that is NOT working is (I
believe) the indicator light for when either brew temp or steam temp
is achieved. You are right that it would be insignificant if it only
indicated steam temp, but that isn't the case. My current thought is
either to add a PID to the machine OR to find a switch from an old
(OLD) Coffee or a Classic or an old Baby that has a lighted bottom/
third switch.
Thanks for your help

That's yours. Trace it out internally, or have a look at the other
models for ideas. Personally, I wouldn't worry about another steam
temperature set thermostat to trip a wire into a added light on
control switch. Though I have one, it's as easy to crack the steam
release knob at the top of the boiler to verify when ready (some go
into steaming early, a tip/trick, as by the time the light's on, and
certainly anything much beyond, steam tends to be on the "dry" side -
not nearly as robust).

Almost but not quite. The old Coffee has the same switch
configuration but there isn't a light in the bottom/brew switch. I
need one just like that but WITH a light.
OR I need to know how to wire it so that the power light somehow
reflects the temperature status....Hmmmm....

On checking more closely, it's not for certain that the one Edward has
is going to work. The one for the Dandy is a Triple Switch about 65
mm tall. The top switch is On-Off and has a light. The middle switch
is Steam, is twice as tall as the top and bottom switches, and has no
light. The bottom switch (the one which isn't lighting for me) is
Brew and has (?) a light.
If you know any more about this switch or happen to have one floating
around in your extra parts pile, let me know.
Thanks.

I believe the Dandy uses the same switch used by Classic & Coffee models.

Actually, it's the same as the old Coffee with the steam valve knob in
front.

On second thought, I'm not sure the switch is the same....still
checking on it. My Dandy switch is a triple; about 65 mm tall. Top
switch is on-off and has a light. Middle switch is twice as large,
controls steam, and has no light. Bottom switch controls brew and has
(should have) a light.
If you've seen one floating around your spares box, or can direct me
to one, just lemme know.

On older machines, yes I'd say a tiny bulb for the indicator light., on
newer machines I'd think an LED. AFSIK these should be in parallel with the
switch so when or if they blow/burn out, the switches will still work.

check the connections again. it does heat up? correct?
then change the switch assy.
