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"#p20141 will be able to help you

@"DavecUK"#p20141 @"DavecUK"#p20141 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 😁

@"CoyoteOldMan"#p20149 thank you, I’ll try it.

@"Roy-Foley"#p20154 As you bought retail, you would deal with the retailer.

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 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.

DavecUK

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.

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.

CoyoteOldMan

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.

Meldrew

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 😅
