The front valve is the relief valve. This opens after a brewing operation to allow the residual water of the brewing group to flow into the drip tray. It should be closed during rinsing. What happens then when it rinses? Is the non-return valve still intact? I mean the brass block in the back. |
I have now also replaced the rear check valve, but the problem still exists. There is an obstacle in the pump system and no water comes out of the outlet nozzle during the start rinsing process.
As well as no coffee with the purchase. I must relieve the pressure building up over the steam nozzle with hot water supply to finish the process.
What could still be the reason . All 3 valves changed, circuit board changed, brewing group completely free with screw-on piston. I am helpless
close
