Title: Nice OWC restoration at HB
Post by: SusanJoM on December 15, 2017, 09:22:56 AM
There is a member over at HB who is doing a very thorough restoration on an OWC.

Yes, it is. I’m following that one. He hasn’t yet opened up the water inlet in the group head, but he’ll probably get to that.

Hey everyone.  It's a shame this site is shutting down; I hope you all considering participating in my thread over there.  I'm having a lot of fun with the machine; and since Andy isn't around, I feel like I'm flying the OWC flag now.

Hey Jack!  I've rerouted the water inlet and plumbed in a pressure gauge where the old water inlet was.  You can catch that over in the HB thread.

Your excellent work and your posts over at HB are evidence that there is no need to have a separate Gaggia forum.  Thank you for breaking ground over there with such excellent Gaggia work.

Oh wow! Thanks so much for the kind words.  While I TOTALLY disagree about have a Gaggia-specific forum  ;D

If Gaggia hadn't shot themselves in the foot (their feet???) by coming out with those nasty stainless steel models, we might have kept this going.   :P

Since it's a little more active here, does anyone know where to get a snubber valve in 1/8 NPT?

I never found one of those, so if you are thinking to use it for the pressure gauge, just buy one that is glycerin filled.  The glycerin makes the snubber unnecessary.  But given your level of interest, you probably already know that  ;)

Ahhh but I love the gauge I have on there.

I called up a fittings warehuose and they directed me here:

303SS
1/8"

Seems like it would work.

Sorry, but you’re referring to the inlet into the boiler. I was referring to the inlet into the head itself, above the shower screen. It’s all dependent on your perspective, I guess. ;) But it would have been clearer if I’d said “water outlet”.

Ah, gotcha.  Yeah, I actually did that as well and posted a video today.  Take a look and let me know what you think of the dispersion of water.

Quick question... While this toggle works to turn the PID on and off, I clearly don't have it wired properly because the LED on the toggle switch doesn't illuminated.  Can anyone help me out with wiring it properly?

Title: Re: Nice OWC restoration at HB

I'm not sure about the LED toggle.  I had to play with one on another project to figure how to get the LED on, even though the switch worked.  Of course LED doesn't make a difference since the PID lights. I played with a DMM and the switch, and connections until I found the sequence.

There has to be a switched wire connection at the machine front, on/off switch.  How about a piggyback connection on the switched so that the front switch turns on the machine and the PID, standard setup? Neutral from the back to 9 (Or you have that and used all red wire?) and switched to 10.  You probably know that to have gotten this far, but I'm curious as to why change?  I realize that the Auber instructions are newer than the old style block in the back, but you still should be able to find a neutral back there and make an easy connection straight to 9, or already done in red.  Or the problem is finding the switched wire, or, not what you wish to do and you want the LED?

Yeah so the red wires from the main are connected to the black and white wires at the terminal bar.  Those black and white wires come in from the power cord.  Ideally, I'd like to have the PID come on with the front switch on the machine.  How do I identify a neutral wire?

When I PID'd my OWC I used a piggyback connector on the top left hand switch connection to take a switched live feed to the PID. You have marked it 1 on the HB thread. The neutral was taken from the unused spade connection on the right hand heating element post. My OWC is UK spec but the connections are probably the same as yours.

Do you have a volt meter or Digital Multi Meter?  You already have the connection at the back post, probably neutral to 9.  Find the switched lead on the front switch.  You can identify the front switch hot lead with a volt meter and then see which terminal is switched on and off.

I just recently picked one up; but I realized I like having the PID and heater on a switch, independent from the machine.

So here's the final product:

Nicely done!
