Hello, it is not easy to give an answer to this. As far as I know there are no hidden switches. If you only replaced the screen, there could be a problem with a power connector. Try disassambling the device, reassamble it again and check every single connector you opened. Are any flatcables upside down? Every flatcable pushed in place? Probably a broken cable (most times you can see this)? Good luck, John
Hi, this instruction was written by Spencer Harding. Sorry I can’t help you because all I could do is use the same search machine as you. Maybe you can find an answer in the comments given before.
Unter Schritt 5 habe ich einen Link angegeben, wo ich das Ventil bekommen habe. Es ist von Jiayin, mit “JYZ-5” beschriftet und hat eine Leistung von 17 Watt.
Unter Ihrem Link findet sich ein “JYZ-4P” von Jiayin mit 12 Watt Leistung.
Optisch scheinen sie baugleich, ob der Leistungsunterschied relevant ist kann ich leider nicht sagen.
Bitte rückmelden, falls es funktioniert hat. Der Preisunterschied ist deutlich.
Measure the resistance of the steam valve coil. If it is infinite you need to buy a new coil. I couldn’t find one. You can get the complete valve (for GC9640) here: https://shop.euras.com/artikelsuche_ma.p... (for Germany).
Sorry Uzayer Masud, I don’t have a solution for your problem. At my Kobo the adhesive still existed, so maybe you are right and the missing tape is part of the problem. Maybe you can use some other adhesive e.g. like for photos. Best wishes for success, John
Sorry Jan, I don’t know either. Maybe someone else can give advice. Good luck. (This guide was written by Spencer Harding, I only added one comment), John
This shows the batterys near end. Jens

Bei unserem bauähnlichen Milchschäumer Petra ließ sich das gleiche Problem genauso beheben.
Danke für die Rückmeldung.

With GC9640 the termistor is 226 kOhm @ 26°C.
Beim GC9640 hat der NTC 226 kOhm bei 26°C
For model GC9640: Thermistor is 226kOhm @ 26°C
In my case steam is produced and I only hear “click” by pressing the steam button.
