Krups Coffee Machine Repair

A Krups Nescafé Dolce Gusto capsule coffee machine whose water pump was not working has been repaired.
The exact cause of the problem could not be determined because when the pump was dismantled and reassembled it started to work.
Possibly some part of the pump has become lodged and when dismantling it, it has become free again.
Although it was possibly not necessary, during the assembly of the coffee machine an apparently damaged tube was replaced, for this the following components were purchased through Ali Express (total cost 7 euros):
- Braided silicone tube with inner/outer diameter of 3mm/7mm. Reference: es.aliexpress....
- Hose clamp set with 7mm diameter. Reference: es.aliexpress....
