Lucky head clean Epson XP-402

[Hugorm]

Have anyone had a possitive way to unclog the printhead of a XP-402 while the printhead was installed?
What method was used?

Maybe this method by @pharmacist will also work for your printer?

I'm currently applying this method - with very little luck and heavy ink use (for nozzle check).
Maybe I just have to be patient?
As I could not easyly buy the liquids I bought a cleaning kit from JETlitetech specially for Epson ink.
(I needed the tubeing and fittings)-

AFAIK Epson printheads are not user replaceable, so they should not be removed for cleaning outside the printer. Maybe one of the Epson experts has suggestions for other cleaning methods?

I bought demineralized water and isopropyl alcohol from "Matas", I bought propylene glycol from an online cosmetics shop. It can also be bought from E-cigarette shops. Concentrated ammonia 25-30% ("Tredobbelt salmiakspiritus") can be bought at many supermarkets.

Still no luck.
Used three sets of ink cleaning the printhead.
