Slow leak into chamber for Bosch Vision 500 series front loading washer

Brand: Bosch
Model Number: WFVC6450UC/29 (in operation in my household for 17 years)
Main Symptom: leaking water into chamber very slowly the amount you see in the pic took maybe 10 hours

What happens & when: happens when NOT using washer but water supply turned on

Probably inlet valve? Hot or Cold I dont know how to tell my shutoff controls both hot and cold together so cant troubleshoot that way. Water cold to touch but that probably doesnt mean anything since the leak is so slow

If inlet valve how easy for DIY for me to fix it I cant get myself to call the local place if I can avoid it probably charge an arm and a leg including for the part.

Error Code (if any):

[Go to the valves and disconnect the outlet hose to the machine, and watch to see which one is dripping and replace that valve, or replace them both since they have some age on them.00422244 Water Inlet Valve | Genuine Bosch OEM In Stock

thanks, not following you completely though. at what point do you want me to disconnect, at the wall where the valve is that controls water from the wall, or at the machine where the hose goes into the machine. Its a tight space in our little laundry room on the bedroom (second) floor, I’ll need to pull the machine out I think, no way to get behind it

I do see the parts you gave one is cold water the other is for hot water though the hot water one doesnt say hot water in the title but calls it Valve-Magnet
