How to Replace a Dishwasher Drain Hose in Toronto

The drain hose is what carries the dirty water off your dishwasher, and it’s often the main culprit when you’re in need of dishwasher repairs. That’s because the drain hose is vulnerable and easily damaged which usually leads to a mess on your kitchen floor when it leaks. So if you find yourself in such a situation, there’s no need for panic. Replacing a dishwasher drain hose is pretty simple; here’s how you do it.

Step 1: Shut off the power supply and water supply to your dishwasher

First things first, disconnect the dishwasher from the power supply to avoid the risk of electrocution. You can do this by unplugging the unit from the wall outlet, flipping the appropriate circuit breaker switch to the off position or removing the correct fuse from the fuse breaker. Try turning of the machine afterwards to verify that the power supply to the unit has been disconnected. Also, cut off the water supply to the unit by closing the supply valve beneath the sink.

Step 2: Disconnect the drain hose from its connection under the sink

Open up your sink cabinets and locate the end of the drain hose. It will either be connected to an air gap or the sink drain. Loosen the clamp that holds the drain hose in place then disconnect it. Place a shallow container below the point of connection to collect any dirty water left in the drain hose after disconnecting it.

Step 3: Pull out the dishwasher

Remove the brackets that hold the unit in place below the counter. Before pulling out the dishwasher, disconnect the water supply lines and the power supply lines from their connections within the cabinet. Use a crescent wrench to loosen and disconnect the water supply line to the unit. Only when your unit is completely disconnected should you carefully pull it from under the counter.

Step 4: Remove the damaged drain hose

Once you pull out the dishwasher, you should easily locate the end of the drain hose connected to the drain pump of your unit. It’s also secured using a clamp. Loosen it then disconnect the drain hose completely. Check to ensure you disconnected the other end of the drain hose below the sink then pull it out.

Step 5: Push the dishwasher back under the counter

Fit the end of the new drain hose completely over the outlet then secure it tightly using the clamp that comes with the new hose. Manoeuvre the other end of the drain hose through the hole in the back of the cabinet leading to the sink. Feed as much of the hose as you can through the hole before pushing the dishwater back under. Do the same for the water supply line and the power line you had disconnected. Push the unit back in the cabinet then gently pull the rest of the drain hose and supply lines through the holes and into the sink cabinet.

Step 6: Final touches

Connect the end of the drain hose to an air gap or sink drain and secure it by tightening the clamp. Reconnect the water supply line and power supply line. Turn on the power and water supply to the unit and that’s it, you’ve successfully replaced your dishwasher drain hose.
