My machine has been working sporadically the last week or so. I’ve had two leaks on top of the service boiler, one was a probe, I was told to use ptfe and this stopped leaking. Next the brass fitting in the middle leaked rather badly, I turned off the machine and let this puddle evaporate. When I turned the machine back on both boilers it tripped out, I then turned it on brew boiler only and it was fine. I unplugged the red wire, I assume to the element and started the machine on both boilers, all good. Putting everything back to normal the machine tripped again.

So A leaked, or hissed? Did it leak onto B, sometimes if B gets corroded, it can go bad and short out…B is a limit stat. How long was A leaking has it ever popped and blown steam out of the top? If you bypass B temporarily and try, does it still trip immediately Is it tripping an RCD, RCBBO or an MCB?

Yeah you got my pm, fingers crossed DavecUK will be able to help you

DavecUK DavecUK Fitting A just dumped that puddle out onto the boiler (@~100c) that you can see. As far as I know it hasn’t done this before but on the second picture, the silver fitting with the fill probe in was hissing steam, I was advised to use ptfe to seal it. I’ve not bypassed the red wires, I can give it a go if you tell me how. It’s tripping an RCBO out. This morning it was running fine but it’s been temperamental for a week. If it tripped I just unplugged it and left it but I want to fix the beaut 😁

ACS Minima is tripping out my electricity.

Cuprajake thanks so much, I love this machine and took a good ear bashing for buying it, you can imagine what she’s saying now that it isn’t working 😅

Roy-Foley

Is this corrosion?

Roy-Foley I’ve not bypassed the red wires, I can give it a go if you tell me how.

Unplug the wires both ends of the stat (thick wires wrapped in cord), then connect them together with a piece of wire - if you have some automotive spade connectors it will be easier, but otherwise just strip and stuff a short piece of wire into both connectors on the wires, making sure there is continuity. INSULATE with some tape - it will be live once the machine/boiler circuit is on.

CoyoteOldMan thank you, I’ll try it.

Also is it an early one or new? It will be on the rating plate

It’s made in 07-21 bought from black cat in September the same year, it’s not a year old yet. I bought it from a friend in march to be clear, I have no idea on the warranty.

DavecUK

Roy-Foley As you bought retail, you would deal with the retailer.

Roy-Foley

DavecUK as I say, I bought it from a friend, I’ve e-mailed Black cat and not had a reply in over a week. Luckily I’m getting the help here or I’d have wasted £1000+

CoyoteOldMan

Black Cat have this on the website…

It also says the Minima has a 12 months RTB warranty, but it doesn’t say whether it’s transferrable.

Roy-Foley

CoyoteOldMan I’m not implying anything bad about them, my friend said they’re spot on, I don’t expect to have warranty because I bought it from a friend. Yes it’s not very old but these things can happen.

Roy-Foley I’m not implying anything bad about them

I didn’t think you were! They are a one-man operation, I think, and they may have put on the announcement on the site (and maybe an auto-response email?) after a couple of days of being unwell, crossing with your unanswered email.

I would definitely do as CoyoteOldMan suggested, disconnect and isolate the high limit trip and see if that cures the issue. I have come across a few of these in my time which look perfectly good but are tripping the machine, this due to the insulation breaking down therefore shorting the power down to earth.

Roy-Foley

Meldrew I’ll do it tomorrow I’ve got some of the connections down at my garage. Thank you all for the help, I need my coffee 😅
