AmenThe Harmans will run dependably even if you do not scrape the pot daily. Ask me how I know....
Really though, Do the recommended cleans and pot scrapes and such as many do here and just turn that bad boy on and enjoy the plethora of heat and no baby sitting at whatever temp you like.
Harman stoves are minimalistic animals in the "needy" department. Many others are still attached to Mom's teat. For life! Ouch! the bullets are already hitting that target.
Set it and forget it. Give it some love every now and then. It will love you back ten fold like a loyal old dog.
