Introduction
The water pump facilitates the motion of water from the reservoir to the drip area. This guide shows how to replace it.
Tools
- 
                  
                  - 
            Unscrew and remove the heating plate layer. This will expose the internal workings of the machine. 
 
- 
            
- 
                  
                  - 
            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. 
 
- 
            
- 
                  
                  - 
            Unscrew and remove the remaining J1S1 screws that secure the water heating element to the interior of the device. 
 
- 
            
- 
                  
                  - 
            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. 
 
- 
            
- 
                  
                  - 
            Locate the coated wire that feeds into the side of the water heating element. Remove this wire. 
 
- 
            
- 
                  
                  - 
            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. 
 
- 
            
- 
                  
                  - 
            Squeeze and remove the clamp that secures the main tube feeding into the water heating element. Remove that tube. 
- 
            Remove the water heating element. 
 
- 
            
- 
                  
                  - 
            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. 
 
- 
            
- 
                  
                  - 
            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. 
 
- 
            
- 
                  
                  - 
            Locate the water pump in the interior of your device. 
- 
            Squeeze and remove the clamps securing the tubes that are connected to the side of the water pump. 
 
- 
            
- 
                  
                  - 
            Trace the three wires leading out of the water pump until you find the connector linking them to the wires in your device. 
- 
            Detach the connector and remove the water pump. 
 
- 
            
To reassemble your device, follow these instructions in reverse order.
