more to consider!
Tony, you should never see the element glowing red unless there was no water at all in the tank and it was in the heat mode.This event can cause serious damage to the element and nearby plastic pieces of the pump and filter assy.Until the 21 series machines and I mean anything less than a superba model, the element never came on during the drying period. Since your machine was the first and only complete series of models that had no heated air dry, there would be no heat at all during the dry period and you would not see any glowing of the element.
Hard to say why the counter was so hot unless the machine DID in fact keep heating the water in the tank.
Did you open the door and see water in it? If so, then it may have the stuck open heat thermostat scenario and may have been close to hitting the hi limit. However, sometimes conditions around the machine could drain off enough heat from the tank into the surrounding area, that while the water was at the sani level, it never reached the hi limit safety level.Like how much heat did that thin insulation blanket really hold in?
I know that this may sound confusing, but the downfall of this model series was the piss poor drying job it did and how it had to have all the best of conditions to retain heat in the tank to dry the dishes. It didnt take Hobart long to go back to the fan forced heated dry system on the -20 series with the no heat option button. The 19 and 20 series cycles were nearly identical with the exception of the heated dry setup.
if you can, try to see if you can tell if the element is heating when it fills.
What does it do now when you use it and was this a few isolated events? I would be interested in knowing.
If you are really handy electrically, you can remove the thermostats under the tank and test them against a 60 watt light bulb who's surface should get hot enough to trip the switch contacts inside of them. dont confuse them as one is the sani stat and one is the safety. the sani stat should "click" before the safety.
Let me know what happens. you can email me directly if you want.
