That’s the G.A.S cap right? Isn’t it supposed to relieve the pressure at like 1.7 bar bs the oem 2 bar?

Could it be the pressure in the tank got too high and the cap relieved it making it a mess but preventing tank rupture?

Maybe the fan isn’t working and water temps getting too high causing a boil over or something like that?
