In addition to cutting the power, you’ll also want to shut off the water supply to the dishwasher. You can verify that the power has been effectively disconnected by checking that the display on the control panel cannot be activated.
Shutting off the electrical power will help prevent any possible electrical shocks while you’re working on the appliance. In this case, simply remove the designated fuse from the fuse box. If you own an older home, you may have a fuse instead. At your home’s circuit breaker, switching to the Off position will completely shut off electrical power to the dishwasher. Before you begin the replacement of your LG dishwasher’s door springs, the appliance needs to be disconnected from the power source.
