Hi @ysagri ,
According to the installation guide-p.5(click on installation guide) the dishwasher installation requires 120 deg F hot water to be connected to the dishwasher.
According to the owner manual - p.15 on a Nominal wash cycle it uses 119 deg F water to wash the dishes but it uses 145 deg F water to do the final rinse.
Basically it doesn’t heat the water for the Nominal wash but does heat the water for the final rinse
I would test the heating element (seen as part #1 - click on Heater parts) to make sure that it is OK.
If the heater is faulty (low resistance, short circuit or short circuit to earth) it will draw too much current and the Bi-Metal fuse will blow to protect the dishwasher.
This link may be of some help as it shows how to check the heater, (further down the page it describes how to check as well). The video and explanation is not specific to your particular model, just a general description.
