Hi folks Found this forum whilst trying to get some info about our Esse cooker, and was hoping that some of you may have one or experience of cleaning these. The big advantage with this model is that it can still run if the electric goes off as it is a vapourising type, albeit the pump would stop. The manual states that there are three flueways, but I have only ever found two (one behind the splashplate at the top, and the other between the two oven doors). The third one is described as "A removable access door/cover at the top back/rear of the boiler" (unfortunately there is no diagram). I have spoken to someone at Esse but still haven't been able to get to the bottom of this - this is not a current model).
