High operating cost. Element has 1/2 inch hard water build-up, i.e. calcium, lime. I change the heating element every 2 months. Does the unit have a thermocoupler? can't find anything in the manual or the...

I think your problem is the buildup, which would cause your elements to work much harder trying to heat the water - especially if you have well water as opposed to chlorinated city water, although city water still has calcium, etc. in it.. Add a whole house filter to your water line where it comes into your dwelling - there are a myriad of elements available at varying microns to catch the calcium
and other contaminants. These filters normally need changed every 3 months - I would check your after a month to see what it is catching. These whole house filter systems are not expensive - check out your local hardware or plumbing store, I'm sure they can guide you to the proper set up ( after you verify what they say through some online research) . Better safe than sorry !!
p.s.there should be 2 elements in your water heater - 1 above and 1 below, so after you've installed your filter change both elements - I'm sure you'll find they last a lot longer!! Also - before you cut off water to your home for the install, fill up a clean 5 gallon bucket and RINSE the filter element , then turn off the water supply to your water heater to prevent a loss of prime and water hammer to the pipes.

Calcium buildup on heating element. It's unmovable.

The reason for the calcium build up is normally a hard water,Make sure the salt dispenser is full (located at the bottom of the machine under the lower rack,before you add salt get a descaller from you local hardware store, most carry for dishwashers.Follow instructions, this may require a few treatments before it is gone,when it is right then check salt level etc.Hope you come right.

Lime buildup

Limescale is mostly calcium or magnesium carbonate and will dissolve in acid. If you don't want to use the commercial limescale removers you could try soaking the element in vinegar, or lemon juice, or coca-cola and then rubbing at the residue with a plastics pan scourer. (Wrap the element in some cloth and keep basting the cloth with your chosen remedy for a few hours before trying the scourer.) If you can reduce the dishwasher temperature below 55C this will help a lot in the future.Hope this helps a bit!
