Whirlpool help

Hi All:

I need to replace the heating element in my whirlpool dishwasher, however the unit was in when we bought the house and after searching everywhere on the unit, I can’t find any model info. I removed the element & took it to a local appliance parts place, but I was told they could not match it without the model number. Any assistance would be greatly appreciated.

Here is where the model labels are usually located

Thanks, but I have searched every inch of the unit, and there is no model or serial number. They are completely missing. Any other suggestions?

Try to find a number off a part then perhaps by cross referencing this back you can find a model number.
Probably the best part to try would be the timer or control board depending which is used in this unit. They are more likely to be used in fewer units/models.
