Problem with Cubica Plus. Water flows through the brew head as normal until handle is filled with coffee. It then struggles to push the water through. Presume this is an issue with the pump, if so, is it worth fitting a new pump or do I use this as an excuse to buy a new machine?

Have you tried the usual tricks to remove an airlock. Does it produce steam ok.

My Cubika plus was a bit asthmatic, a descale sorted it out.I used the Gaggia descaler but others work ok.

Are all the holes in the basket blocked? Did it come with different baskets for one and two scoops? Swap them over and see if the other one works…

Have had this with a well used machine

Have you ever cleaned it with “puricaffe”

might be worth a shot
