Why did the keyboard pcb fail?  Steam leak, moisture?  Makron, above, mentioned steam leak as underlying.

I am unsure as to why that board failed.
visually there was no signs of water/steam/corrosion damage/board discoloration.  it looked good as new.  No solderjoint issues, and the LEDs passed diode testing.
I am attributing the failure to randomized fallout (bathtub curve type of situation) for the chip on the board.

I am going to bring some pcb conformal coating material home and seal up the pcbs.


Oh I wanted to mention that the entire back of the pcb is covered with a double sided sticky tape.... painful to remove.  
And when you buy the pcb it doesnt come with any (purchased at WLL)
Luckily I had a roll lying around.
and I busted one of the white mounting clips when trying to remove the entire keypad assembly.  I would suggest using a small flathead screwdriver to loosen up the white encasement to the housing.....

I too also changed the ribbon cable, because before one month all LEDS went out. The truth is that I opened and closed the machine very often and the ribbon had struggled. If someone change  the keyboard  I suggest to change the ribbon cable also, for just to be sure. It is very cheap.

BTW after all those months I have not any more problem that I had with machine start working without pushing any button.

after a short stint..... new problems:

Recently I have a new failure mode that I need help with:

When I power on, the device front panel leds all start up as normal, within 2 seconds i hear a click and the power gets cut.

Analysis Looking at the parts diagram:
#37 (Part #5332004000) Two way switch makes consistent switching connections, 0 ohms when engaged.
#65 (Part # 189428300) 175F thermostat on the steamer is reading 26 Ohms
#19 (Part # DM1040) Fuse is reading 0 Ohms
#20 (Part # DM1168/K)  Boiler Thermostat T.107 is reading 0 Ohms

Questions)

1) Item #20 above, what should the resistance be at ambient?
2) Any suggestions on what to test/replace.... I am jonezing for some good brew.


Also.... the gaggia baby twin seems to be a pain in the A$$
is there another variant model, that makes use of the same parts (I am thinking of ordering another machine to keep downtime to a minimum)

now I am just frustrated:

So I ended up getting #37 ( Part# 533200400) ON/OFF switch; and that got the machine functional....
but you ask oh - I thought you check that in the prior post - ...
I did... if you push a bit on the the prongs - it will open up....didnt catch that at first....

Then, after replacing the switch and the Baby Twin stayed on, I thought I was in luck.... put it all back together and made a brew....
and no $hit, I have the steam issue again(strong steam for a bit then off)...

I will have to go back thru and redo some water rate tests again tomorrow.


I have made a bunch of cappo addicts, and I may need to get a backup machine so that I can keep the addicts at bay    ;)  100% uptime required!

Now realizing that I have been accumulating some extra parts here and there I figured that I would get a BABY CLASS and not another twin.... I have had it with all of the extra pcb's etc.
The BABY CLASS seems to have alot of the same parts, just lacks the extra boards, the thermoblock, the flow meter....
I understand there is alot of complaints about leaks, and in general seems like the suggestion is to get the CLASSIC.....
I am kinda stumped on what to do...  I need to have less downtime.  I probably have $100+ in spare parts for the TWIN....


Anyone have any thoughts?

D4F :
looking at the Gaggia site it appears that the classic is not actively shown in their PRODUCTS but is classified as "OLDER".... it appears as if the parts are common, but will there be any SUPPLY issues as far as new parts go?

----------------------------------------------

Back to my problem...  STEAM cutting out after 30s....(and yes I can hear the pump in working in the background, so it is not the issue shown at the end of the video link: Click Here (community.wholelattelove.com)

1) multiple tests: 8oz of hot water come out in 24, 24, 25s.... thus the pump is working fine, and there is the correct amount of FLOW.
2) I have re-re-re cleaned out the flow meter
3) for $hits and giggles I am going to replace the steam Thermodisc from the G5 229C to the G5 240C as per Jan 8 2013 post I did in this thread.




Does anyone else have any ideas on what to look for?

or is this just a case of a ventilate error being that the flow meter is botched?
is there a way to trick the output signal as to trick the system into not allowing the ventilate error to occur, ie short some pins or some bypass?

Thank you for your time in this

I don't see the suggestion that older is discontinued, though that has been rumored since 2009 with Gaggia - Saeco - Phillips.  Many of the Gaggias share the aluminum boilers so parts are common, in fact the Twin has the similar boiler, group, 3 way.  I hope that we will all have parts as needed :)

Good luck with the Twin.
