Hello,

I am new to the forum and definetely not an expert in coffee machines. I have a Siemens Surpresso Compact that I have disassembled to replace the feed pump. Before completing the assembly I have tested the functionality, but the empty water tank led is lit together with the steam knob led, as if the water tank was empty and I needed to charge the circuit again. Have tried to turn the steam knob to charge the circuit but it doesn't work.

I have disassembled again and checked for the water circuit to be filled up to the water feed pump suction, and the water is there. Don't have any clue as to the solution.

Can anyone help?

Thanks

Maurizio
