Hello,

It is possible that the problem is with the water pump or the thermal block in your coffee machine. If the pump is not working properly, it can prevent the water from circulating through the machine and cause a lack of heating. If the heat block is damaged, it can also prevent the machine from heating properly.

I recommend contacting the customer service department of your coffee machine brand for help in diagnosing and repairing your machine. They will be able to give you more specific advice depending on your machine model.

Sincerely.
