Replaced the heating element twice in one year. any idea what the problem is? The original heating element lasted just over one year and the replacement lasted just three months. The motor fan wheel seems to take off slow at first then pick up speed?

The most obvious is that quality matters. Always buy OEM parts from Hobart and not copies from China sold by eBay or Amazon.
One further off the wall thought, running a 200v element on 220v power? If the element is right for the voltage, it can't be over run. The machine is advertised as 'wide voltage' AM15 DISHWASHER TECHNICAL MANUAL 208-240V/60/3. It has a 5 KW element and voltage specs from 200 volts to 415 3 phase depending on model.
From your description of distorted, bent and flaking, certainly suggests is has been used dry. This is an interesting unanswered question. Contactor not shutting power straight way?
possible short in the wireing or a lint build up in vent and housing, blower unit etc CHECK UR THERMOSTATS WITH A METER ESPECIALLY THE THERMAL CUT OFF AND THE HI LIMIT AS WELL AS CYCLING
It sounds like your ceramic elements are cracked and will have to be replaced. This can happen when cold juices drip directly onto the red hot ceramic elements. The cracks can sometimes be hard to see. The latest generation of TEC grills have done away with these ceramic elements.
If the fan is working o/k, but there is no heat, then it is more than likely the element that has failed again.
The fact that you had it replaced a year ago, does not mean tha it will last a long tiime, it is quite common for them to fail in a relatively short space of time.
Take my advice and fit a new element.
Thankyou.
don't have a solution, but i can say the identical thing has happened to me. my heating element has burnt out after only 19 months. i don't know if i should replace it. did you buy a new machine? if so, which one.
thanks
If air flow is restricted this can cause it. Or if your voltage is high or if you have received an element that has been stretched and is loose this could cause it. You say immediate and how long in loads or time is this? Are you sure the element still has full voltage (220V aprox) to the element?
