I have a Kitchenaid dishwasher about 5 years old which I now have a problem with. I started the machine, it was running, I smelled burning, looked inside, machine was running without any water, coil was heating, and of course spilled food etc was what smelt like burning. I could not get this machine to fill regardless of cycle, but what I thought was strange is that it went into the wash cycle as if it had water in it. I thought that there was a control which monitors if the water has reached a certain level, and didn't think the machine would run without water. I thought this could have been very dangerous, or even started a fire with the coil heating without water, if I had let it go and plastics melted on to the coil from the heat. I am not sure if this is a fill valve issue, or an electronic one? I am debating if I should fix the machine or replace it. The washing results of this machine has been very poor since the start, so I am undecided.
