John_Yossarian ACS directly will be better

John_Yossarian

A stupid question, but where do I find the srial number of my machine? I will need it when I contact ACS for the magnet.

Behind the water tank

Its called hiding in plain sight 😎

John_Yossarian

Adrianmsmith Thank you very much!
I have not forgotten to take pictures when changing the magnet, first I need to contact ACS.
BTW I noticed that you had the Vesuvius boiler blown up diagram. Do you happen to have the machine blown up diagram as a whole or the separate compartments?

DavecUK Thank you Dave!
I found it at the old Tapatalk site. If I sent the serial number and the fact that I bought it directly from ACS would this qualify me for a free magnet sent over?
I will contcat Maria later today, I just need to dig out the SN behind the water tank thanks go to @Adrianmsmith

Doubt it…

John_Yossarian

DavecUK There is no harm in asking, the worst would be a “no” answer. I have sent an email to Paolo with cc to Maria at info@elcor.it

Maria at ACS was flash quick and yesterday I got the magnet.
Can someone advise me what the best way to take out the pump would be?

I have tried to find a blown up diagram, but it seems ACS do not have them on their website.

I found @DavecUK YouTube video where he skilfully removes the covers and this will be my last resort.

I am thinking to open it at the water tank side and go from there.

Thank you in advance!

John_Yossarian Did u have to pay for the Magnet?

John_Yossarian

DavecUK It cost me EURO 80 inclusive of postage which was the price of the magnet (39.20 the magnet 40 DHL).
Any advice on how to remove the pump?

John_Yossarian Any advice on how to remove the pump?

If you cant get to it from the bottom, probs one or both boilers have to come out….which is much easier than it sounds.

DavecUK Hi @DavecUK ,
After some travelling and vacation, yesterday I decided it was high time I replaced the magnet. I opened the top lid and after some thinking decided to replace it whilst the pump was still in the machine.
I will not bother you with the tiresome procedure (2-3 hours) that no a sane man would/should do. After repeating the process several times, I have finally put it back.

The instance of truth was when I switched the machine on and the display stayed black.
No RCD was tripped in the process. I might have done something in the process, trying to keep the cables aside. During the replacement, I had to put back the charging cable of the pump, the PCB showed up.
I hope the pump is still in good shape, but before I check that I need to figure out where I have lost the current.

Is (are) there obvious things I need to check first?

I was hoping to take a shrotcut, but it seems a full strip (boiler removal, Gigar box, SSRs) might be on the cards.

I look forward to receiving your helpful advice.

Supplier went back to Fluid O Tech after realising the entire batch was the same. They received their next batch early this week and they informed that they are the same. Fluid O tech informed the supplier that these are the only versions available now….unsure if ACS can get a different version.

With that in mind I measured up and ordered some FKM (Viton) O rings, BS111 size and they came today.

Perfect snug fit around the base, 6 turns of PTFE on the thread, fitted it in and nipped it up, looks like we are back in business.

I had a similar heart stopping experience and i had disturbed but not fully disconnected the ribbon cable to the back of the display, which soon put my heart back in rhythm when i shoved it back in and powered back up!! Hope you have done something similarly simple to fix once traced .

Good luck.

Thank you very much! I will look into it after work tonight.

John_Yossarian The Gicar displays, although very old technology, are pretty reliable.

This evening after dinner, I took over the kitchen floor and opened the top lid. I have to admit that the place to put the ribbon (both of you were spot on, the ribbon had disconnected) is not the most accessible, but after a while I have managed to put it back in place. With a good dose of trepidation I switched the machine. No cigar! I was crushed at this stage and then I remembered that the ribbon has another end that might have suffered the same fate. Opened the Gigar box and …. voila, both ribbons were disconnected.
Put it back, left the box open and once again switched it on. This time I enjoyed the familiar blue colour of the display.

I repeated it a few times before I assembled it back. Checked the pump, it easily hit the 9 bar on Profile 2.
Tomorrow morning I will play a bit more. One of the silver lining of the whole ordeal was the fact that for the current coffee beans we are drinking I came a cross a very sweet spot at 7.5 bar. My wife came to ask me what coffee I was using, that sweet the taste was. I will explore this effect as the difference in taste was remarkable.

Thank you very much for your helpful advice! This by far is the best coffee community, not only in the UK, but globally.

Cheers!
