OK, that's my espresso machine main wiring harness. I thought it had just touched something hot like a boiler tube or something so I re did the molex connector and was back in business, or so I thought.
This is the new molex after about a month. I think the connector was not making good connection as it is a 110v power wire.
They use a pretty skimpy 16ga wire for all that power.
My plan is to bypass the connector and run a wire direct to the switch from the filter. No need for a connector on that.
of course finding all this on my island is a joke so I have to bring stuff in which is a 3+ week wait
I stuck my Thermopen on that wire at startup while the boilers were heating and I was getting a 300 degree temp on that wire.
