pressure vessel as most likely gone are both valves flow and return open. is punp running.the vokera as a problem with the knobs on the front breaking in the pcb they feel like they are ok but are not.boiler will run but won get hot.go to boards and turn stats up manually.are rads open so water can circulate.
