    I removed boiler and held nut with the vice and turned the boiler. I figured it was safer than bending pipes or trying to hang onto boiler in-situ

    Just a small note I have one of these apart on my bench that I'm rebuilding the element nut is more around the 36-37mm mark I took the boiler to work and used one of our mechanics impact gun I don't remember the socket size I just put a ruler across it just now to get that size. It might be possible to remove through the bottom inspecting cover but you will need an impact gun as the only thing that holds the boiler in place is copper pipes and if you try to move it with a breaker bar or something you will twist all the pipes.

    Yep, I had issues with similar board in my junior extra. Replaced with a SSR. Plenty of room in the extra

    Not the Splendor in particular but plenty of people have done it to other small HX machines. There's no room in the Splendor case for a PID and an SSR to be securely fitted either. You could cram them in but it probably wouldn't look much good and the SSR wouldn't be heatsinked properly.

    In my opinion it's a largely useless modification as well on this type of machine. A good pressurestat with a 0.2 bar deadband or better and a properly tuned thermosyphon circuit will be as accurate as you would ever need. I recently finished tuning my own Splendor and have a boiler pressure of 1.375-1.5 bar and a group temp of 94C with no cooling flush ever.

    I will cover your main question as you have a few in there.
    .
    Most likely your heating element is faulty and needs replacement along with a new element seal.

    You can test your element resistance with a multimeter should be 30-50 ohms (power off obviously). Another test you can do is to remove the heating element connectors to remove it from the power (tape up with electrical tape to avoid shorts) and test your machine. If all other functions work like pump, auto fill then it is most likely a faulty heating element.

    Cost of parts circa $100 and you will need a 28 or 30 mm socket to remove the heating element easily.

    Hi all, first post!

    I have the Unico Splendor, upgrade from a Sunbeam entry level.

    I was hoping for the group's guidance - The Splendor was working perfectly until recently - Now tripping the house power circuit when switched on.

    Wondering if there is a circuit fuse I should be checking before calling a technician to fix?

    I am also asking as I don't want to have to pay for a whole control board replacement if it's possibly a $2 fix.

    Many thanks

    Matt

    I never got round to posting completed photos of this machine. It came out fantasitic and worked like brand new again it did spend a bit more then a month at work brewing up better coffee then any Café in Beaudesert the crew at work were disappointed when it went off to a new home I still have one more sitting there waiting to be be given a new lease on life as well and some others, By the looks of things we'll all have a bit of spare time shortly.

    Anyway here was the finished machine

    Here is my setup:

    Diadema (BFC) Junior Elite HX machine and a Compak K3 Touch grinder.

    The Junior Elite is about two years old and was an upgrade from a Rancilio Silvia, which I had for about 4-5yrs. The K3 is the only decent grinder I've ever had and has been going about 6-7 years now.

    Servicing / Maintenance question: I bought the Junior Elite from CosmoreX up here in Canberra. They advise that the macine is not really user descalable and that other than backflushing with a cleaner and maintaining the in tank water softener, it should be taken in for a service every 12 - 24 mths (depending on use). That will cost an average of $250 - $350, plus another $200 - $300 if the boiler needs a full descale. Mine is now due for service, fingers crossed it isn't $650 including full descale! Does this sound right though?

    There are other discussions above regarding user descaling. I've also found this clip describing how to descale HX machines: https://www.youtube.com/watch?v=yEGfyJkWSqU I think I'll drop the machine into CosmoreX this time, as I believe descaling if it is long overdue can cause scale chunks to do other damage, but should I be descaling in the future? (Particularly post warranty period)?

    Old relay board. You can see the points side is blackened inside and the top has started to degrade. Very timely upgrade

    SSR wired in, and working again.
    Cleaning the points on the sub-board relay didn't work for long at all.

    Will get it screwed down after a week or so of testing.
    Woohoo!
