Chosen Solution

When I press steam or water button, steam or water squirts once but the rest of the water gets collected in the tray below. Coffee maker side is working without a problem. I have even removed the frother assembly from silver pipe but same result. Please suggest what is the problem.

Did you replace this solenoid valve? Or this one behind the front panel?

CONFIRMED. Steam solenoid valve was the problem. Please note that the replacement Jura part for USA must be the 120V version, not the 230V version used in Europe. They are unfortunately more than twice the price from what @vauweh shared with us in his posts, and as of Jan 2021 both jura-parts.com and partsguru.com are out of stock. Here is the USA part I used for my C9, but it’s designed for C, F, S and X machines Jura-parts: https://www.jura-parts.com/Jura-F-S-X-Se… Parts Guru: https://shop.partsguru.com/Jura-Steam-So… Parts Guru also has a conversion kit for older S machines, which lets you use this valve instead of the original, which is apparently no longer available https://shop.partsguru.com/Jura-Steam-So… would be great to find a DIY approach here. good luck!!
