First I unplugged the dishwasher from the outlet. Then disconnected the water feed and waste water return lines. Removed the dishwasher from the counter and removed the lower metal panel to access the heating element nuts. Installed the new nuts and tightened them. Reinstalled the connectors to the heating element and put the dishwasher back into the counter. Reconnected the water feed and return lines and plugged the machine back in. Tested for proper operation of the machine and verified no other leaks were present.
