Your dishwasher works by spraying your dirty dishes with a stream of soapy water, leaving the dishes sparkling clean for your next meal or dinner party. The water gets to the dishwasher through a water supply hose, which is usually hooked up to the hot water supply valve located beneath your kitchen sink. Although these hoses are built of sturdy materials, in the cluttered world beneath your kitchen sink, sometimes they can kink, which can cause leaks. In that case, you'll need to remove the inlet hose from the dishwasher to replace it with a new one.
Turn off the electricity to the dishwasher. In the majority of installations, do this by turning off the electricity to the circuit that the dishwasher is on at the main breaker box.
Shut off the water supply for the dishwasher, which should be located beneath the nearest sink. Examine the sink's water supply valves. The one that is connected to the dishwasher has two water supply lines running from it. Turn the water supply knob on this valve clockwise to turn off the water.
Disconnect the inlet hose from the supply valve. Place a towel or rag beneath the water supply valve you just turned off. Determine which water supply hose is going to the dishwasher by tracing the hose to see where it goes. The water supply hose for the sink leads upwards to the faucet above, so the other line is for the dishwasher. Disconnect the line by loosening the coupling with the pliers or wrench. Wipe up any excess water.
Unscrew the bottom part of the front panel from the dishwasher. This is the part located beneath the door. Set it aside.
Locate the inlet hose on the front of the dishwasher. The inlet hose is connected to an elbow joint somewhere on the front of the machine. Use the wrench or pliers to unscrew the water inlet hose from the elbow joint. Keep a towel handy because some water will dribble out when it is disconnected.
Pull the inlet hose out from the dishwasher. Tug on the inlet hose from the end that was connected beneath the sink because this will probably be the easiest to remove.
Always use caution when working around water and electricity.
