Yo, sorry for so long delay, but i tried to "try all possibilities" before spaming again. However, even after purging the system, it still fails to work properly. Upshot is, my bargraph never reads anything. even while manually purging, instead it just lights both leds. Durring drive test, i get blip of "B" along with sound of pump kicking in, and than failsafe kicks in. is there any contact on for ex. flow sensor, which is prone to fail if, dunno, is freezing, dirty, too near to source of heat, or christmass too near?
