So, the Smonelli super-automatic espresso machine took a small dump. Indicated a "Coffee temp sensor error."
Anyway, I downloaded schematics and looked up the part. $39. No prob. Called Nuova Simonelli, and they suggested I take it to a local Italian Food Service Co. for repair.
So, in good faith, I took it over. $85/hr, one hour minimum. That's fine.
So, THREE WEEKS LATER, the tech, who funny enough was named "Luigi", called and said "I think I've narrowed it down to the temperature sensor."
"You mean when you turn on the machine and it says "WARNING: TEMPERATURE SENSOR"? Okay, Luigi. Thanks.
Anyway, I approved the installation of a new sensor, and he said he would button it up that day.
ONE WEEK LATER, They call. "Uhhhhh, well, we can't get the machine to heat, we think it's the main board.
New board is $632.
"Sorry guys", I say. "I'll come get it."
So, I get the machine home and tear into it. Unfortunately, LUIGI connected a few of the single-wire spade connectors onto the main board BACKWARDS. No electrical problem, but a problem that most likely made him replace the relay that he replaced on the board.
So, if Luigi can't even keep the connectors straight, and I have a schematic, I'm going to fix it myself. If I screw the pooch, I can buy and replace the main board, which was what he was going to do anyway.
I replaced the old board correctly into the machine and it heats fine, but the temp relay won't switch off. The new relay soldered into the board by Mario, er, I mean Luigi, had kind of a goober-ed up solder job, so I'm hitting the solder joints again.
My question, should these big fat printed traces on the back of the board (behind the relays) have continuity with each other? i'm talking about the three main big ones. They should have continuity amongst themselves, right?
I'm just trying to avoid the buying a new $6xx main board if at all possible. I'd call and scream at Luigi, but I'm not going to let his worthless ass occupy space in my brain.
TIA!
