TRIAC PCB ASSEMBLY

"Steam leaks from damaged o-rings resulted in damaged pcb when i noticed that it was heating the boiler without being powered on. i replaced my old pcb with this new pcb. i couldnt solder so i used twist wire connectors."

"There are screws near the brew head that must be undone so that the top of the machine can come off. you must use new heat sink paste on the triad pcb or it will fail prematurely."

"Replaced with new triac pcb"

"Fix steam leaks first. join wires and use fresh thermal paste."

"There is plenty of good advice about fitting this pcb on the bigwarehouse spares site but just to add a couple more points - take lots of phots-vids of each step - memory cant always be trusted. - dont cut any wires from the old pcb until you are ready to connect the new one. even then only cut and reconnect one wire at a time to avoid confusion. - dont forget to clean off the old thermal paste from all the surfaces and parts. it gets everywhere if you dont and dont apply any new paste until ready to install. - each wire on the pcb is a different colour and the arrangement and colours of the wires are the same on both pcbs - easy. - observe where the old wires go and remove zip-ties as necessary to allow more room to work on the part. - screw the new pcb heat sink and plastic cover lightly and temporarily in place (no paste yet) and in the same orientation as the old one. this will save any future frustration, avoids tangles, and putting unnecessary tension on the wires and pcb. it also makes life easier when connecting wires. - before cutting the old wire follow it along its path with the new wire up to the original crimped joiner. each wire goes to a different location so this way all the new wires should end up being in the same place following the same path as the old ones with no tangles and leaving plenty of slack in the wires. - connect each wire in turn using your preferred method crimped connectors, solder and heat-shrink, or a combination. two of the pcb wires each join to three others which can get tricky when soldering. all of the others join one to one. - when all the connections have been made and are well insulated its time to permanently re-install the new pcb. apply thermal paste to the back of the heat sink on the yellow plastic sheet on the underside of the case lid where the heat sink makes contact and on each of the three wire ends that screw onto the heat sink and also on their individual locations on the heat sink. you dont need much paste. apply it thinly and evenly over the entire contact surface. - clean up any excess paste after final assembly of the pcb to the case lid. - tidy up and relocate the wiring as originally found and replace any cut off zip-ties with new ones before closing up the case. - add water, coffee, and electricity. then if all is well make yourself a cup of coffee and sit back enjoy your fresh coffee and admire your handywork."
