Hi guys,
My old vaillant boiler has the I/O indicator blinking which i've read is the overheat thermostat. I've found online what the overheat thermostat looks like for other very similar models but not mine, cant find it anywhere.
Am I able to manually reset on this boiler?
Would a photo help?
Many thanks guys
