Afternoon all,
I recently bought the Minima that was for sale here as a repair project, and while i wait for it to arrive I thought I would start info gathering as I’m completely new to this level of machine. If anyone is able to provide and guidance or point me to guides etc I would be most grateful Below are the all important details:
The post said:
"Minima has now started producing watery steam which I guess is from the boiler overfilling.
Just to compound the fault the steam boiler has also started overheating which I have no clue about.
It was bought new from Bella Barista in April 2019 and used solely for me and my partner a couple of times per day
As its become faulty I have recognised that I do not havethe technic al knowledge to fix it and also I lack the inclination to get involved with it. I should add that the brew side of the machine is working perfectly so for an espresso fan it might just be perfect"
And Dave’s kind advice on said post was:
"The boiler over filling was an issue due to I think electrical interference . in the early models e.g. 2019, the Gicar box autofill probe has a wire to the probe and a wire (black) that needs to be grounded. They did this on the boiler and not the frame. The electrical interreference meant it sometimes overheated. That wire was later moved to a grounding on the frame and the problem went away.
The overheating will almost certainly be a temperature sensor requiring replacement
So it probably needs just a temperature sensor and the earthing wire moved to the frame. At absolute worst, it could be a faulty Gicar Box where one of the triacs has failed closed…it all depends on how it overheats."
So if anyone is able to assist with any videos, guides, etc on how to approach these jobs as a first stop that would be great. I am told the earthing query has been addressed. Also to find out the different ways in which these can overheat as mentioned above, will help me.
Thanks in advance. Mark
