Ninja Coffee Bar CF086 Power Cord Replacement

Step 1 Water Heating Element



• Make sure the Ninja Coffee Bar is unplugged and that you have a dry, clean workspace for this task.
• Remove the carafe and water reservoir and set them aside.
Step 2

• Unscrew the T-10 screws from the bottom cover of the machine, and remove that bottom cover.
Step 3
• Unscrew and remove the heating plate layer. This will expose the internal workings of the machine.
Step 4
• Locate the water heating element in the interior of your coffee maker.
• Unscrew the two indicated J1S1 screws at the base of the water heating element.
Step 5
• Unscrew and remove the remaining J1S1 screws that secure the water heating element to the interior of the device.
Step 6
• Grasp and remove the clamp securing the tube that feeds into the base of the water heating element.
• Detach the tube from the water heating element.
Step 7
• Locate the coated wire that feeds into the side of the water heating element. Remove this wire.
Step 8
• Locate the two wires leading out from the water heating element that feed into crimp connectors.
• Using side cutters, sever these wires near the crimp connectors.
• Use the side cutters to cut the remaining wires that feed into the crimp connectors from the coffee machine.
Step 9
• Squeeze and remove the clamp that secures the main tube feeding into the water heating element. Remove that tube.
• Remove the water heating element.
Step 10
• Using wire strippers, strip the cut wires from your coffee machine near their cut ends to expose 2 cm of metal conductor from each.
• Use a similar procedure to strip the wires from your replacement heating element. Using wire strippers, expose 2 cm of metal conductor from the ends of the wires.
Step 11
• Prepare two crimp connectors by filling them with dielectric grease.
• Use a crimp connector to connect a stripped end of the wire leading from the replacement heating element to the stripped end of the corresponding wire from the coffee maker.
• Using a second crimp connector, repeat for the remaining pair of stripped wires.
• Using the appropriate crimping tool, crimp the connectors.
Step 12 Power Cord
• The power cord splits into two and feeds into two closed-end crimp connectors. Two wires from your coffee machine also enter these connectors.
• Locate the neutral wire that feeds into the crimp connector from the machine. Mark this wire.
Step 13
• Using side cutters, cut the wires from your device below the crimp connectors.
Step 14
• Using wire strippers, carefully expose a 2 cm length of the metal wire from each of the cut ends.
Step 15
• Apply dielectric grease to the insides of two new crimp connectors.
• Insert the stripped ends of the wire into the crimp connectors.
• Locate the ends of the replacement power cord. These should be already stripped; if they are not, strip 2 cm from them using wire strippers.
• Feed the ends of the replacement power cord into the crimp connectors. Crimp the connectors using the appropriate crimping tool.
