KRUPS Type KP1006 coffee maker - Nescafé Dolce Gusto - Review of interior components and faulty water pump.

ID: 157239

Description:

Steps:

1. Nescafe Dolce Gusto coffee maker model PICCOLO, the housing of this machine is entirely formed by plastic type hooks, so it is not a machine designed to be disassembled and reassembled several times, since the hooks deteriorate or break quite easily, I show in the photos the ones it carries

2. View of the housing from the back indicating where the anchors are located

3. View of the separated casing.

4. Detail of the ring-type anchors at the bottom, they are the most difficult to unhook since you need a hook (the one in the photo is homemade).

5. Details of the hooks on the upper part, as we can see this machine uses anchors of 3 different types.

6. Indicative photos of the various components of the machines:
7. Photo 1 Water heating boiler, internally incorporating a resistance.
8. Photo 2: Power input thermo fuse directly in contact with the boiler so that in the event of an abnormal rise in temperature, the fuse cuts off the input power.
9. Photo 3: The same as the fuse in photo 2, but it is placed on the other input power cable.

10. Photo 1: Water pump, absorbs water from the tank, sending it to the boiler, at the top of the pump, we also find the NTC temperature probe.
11. Photo 2: Rubber membrane type ON button (OFF is automatic on this machine).
12. Photo 3: Hot or cold water selection button, very typical in this series of machines.

13. Photo 1: PCB electronic board.
14. Photo 2: Detail of the RESISTANCE WITH FUSE FUNCTION located in the center of the board, but electrically linked to the power input connector, it can burn "cut" and aesthetically we will not observe anything, it would give the same type of symptom as one or both power input fuses blown, machine completely OFF.

15. Water pump or water impulsion pump, is not one of the most common breakdowns, but the breakdown can occur, that the machine turns on, the button is blinking green and the machine does nothing else, does not drive the water, in this video is the specific fault it has.
16. To remove the faston connectors from the water pump, these connectors have a tab or safety clip, so that they do not accidentally come loose, to remove them, you have to press said clip at the same time as it is stretched from the connector.

17. Example of how to remove the 2 Faston connectors.

18. Electrical check of the water pump, (I dedicate another more specific and extensive document, here I only make a note), We will use the multimeter in Ohm scale, 20 M or 10 M scale, whichever one our multimeter has, OJOOOO we must measure the pump of water in both directions, that is, +,- and -, +.
19. The winding of these pumps has a diode internally so in a +,- direction it can give us an open circuit 1. in the multimeter and falsify the measurement, which is why it is measured in both directions.
20. This specific machine has the water pump winding burned open, that is its fault, it was not repaired since the cost of the pump exceeded 50% of the cost of a new machine.
