Tilt the coffee machine and disconnect the bottom housing by pressing a flathead screwdriver against the snap-fit (CAUTION). There is a total of 6 snap-fits. (Two snap-fits at the rear are not visible in the picture)
Beware of not applying too much force when pressing snap-fits to avoid bending (ánd breaking) during the repair.
Disconnect the two cables (white-brown) from the red pump by pulling gently. If the cables are hard to remove, carefully use flat nose pliers to pull the cables.
Remember the position of the cables for reassembling the Senseo machine. Marking the location and the cable with a different color marker, can be a solution.
Disconnect the red, blue and green/yellow cables from the boiler.
Remember the position of the cables for reassembling the Senseo machine. Marking the location and the cable with a different color marker, can be a solution.
Remove the two white cables, so the printboard (PCB) is no longer connected to the internal components.
Remember the position of the cables for reassembling the Senseo machine. Marking the location and the cable with a different color marker, can be a solution.
Remove the nut from the plate against the PCB, using a Phillips screwdriver.
The order of loosening the snapfits now is important. First carefully press out (in an upward direction) four click fingers (from plastic buttons) that hold the plate in place, and then push out four pins in the PCB (holes marked with black arrows), which loosens the buttons. Beware of not affecting the transistor integrity when removing the plate.
Remove the snap-fits of the PCB, so the plate and the PCB can be disconnected. Use a flathead screwdriver for punching and sculling.
Obvious characteristics of a damaged capacitor are leakage of a brownish fluid, corrosion, or severed leads. Non-obvious signs could be measured with a capacity gauge (for the professional handyman).
Search for the pegs of the capacitor on the PCB and warm up the soldering iron. Remember orientation (left-right)!
The capacitor specification should be: 470nF, min. 275 VAC, 22.5 mm pitch. Only use X2-Class qualification which can be distinguished on the part. Capacitors come in blue and yellow colors.
Caution: the soldering iron will be hot. Perform this action in a well-ventilated area.
Replace the capacitor by soldering a new capacitor of the same type on the exact same spot:
scratch the green plastic of the printboard (with flathead screwdriver) to improve conductivity and cohesion;
keep the capacitor on the right spot, hold the tin against the pegs of the capacitor and heat the tin with the soldering iron. The tin will cool down and the capacitor will be fixed.
Caution; the soldering iron will be hot. Do not breath the soldering fumes. They are toxic. Perform this action in a well-ventilated area.
Reassemble the Senseo coffee maker. The suggested actions during the disassembly should now help you greatly. Be careful with connecting wires (in the right way), tilting and reconnecting the boiler, and closing the housings and snap-fits.
Tip: by following the previous 15 steps in reverse order, reassembly should take 15 minutes.
