The drain hose in the part that carries dirty water from your dishwasher and drains it away. The hose is usually made of corrugated plastic which is prone to kinks, blockage or leaks; all of which lead to a huge mess on your kitchen floor. While it is possible to clear a clogged drain hose, a damaged one simply has to be replaced. Fortunately, you don’t have to worry about the cost of hiring a plumber since replacing a drain hose is one of the simplest plumbing DIY projects. Here are some steps you can follow to get your dishwasher back in business:
- Adjustable wrench
Step 1 – Disconnect the water and power supply
Always remember to shut of the power supply before you begin working on any electrical appliance in order to avoid the risk of electrocution. Unplug your dishwasher’s power cord from the wall outlet or switch off the power from the circuit breaker box. Before you continue, confirm your appliance is really off by trying to switch it on. The next course of action is to disconnect the water supply. Do this by closing the supply valve of the appliance; it’s usually located beneath the sink.
Step 2 – Disconnect the drain connection
Locate the drain connection below the sink then detach it. Use your adjustable wrench to unscrew the nuts that usually hold the drain connection in place.
Step 3 – Pull out the dishwasher
The unit is secured by brackets that hold it in place below the counter. To access the drain hose, you need to move in from beneath the counter. Use your screwdriver to loosen the screws holding the brackets then pull out your dishwasher. If you’re having trouble sliding it out, the wiring or water supply lines don’t have any slack and are probable tangled. Untangle or disconnect them entirely before proceeding.
Step 4 – Disconnect the damaged drain hose
After sliding out your dishwasher, it should be easy to locate the drain hose. It’s usually found at the bottom of the unit towards its left side. Trace the hose to find its two connections, one at the drain pump and the other one at the sink drain. Before disconnecting both ends, place a bucket below the sink drain connection and a towel below the drain hose’s connection to your appliance. This is to collect any dirty water still inside the hose when you disconnect it. Using your pliers, squeeze the wire hose clamps that hold the ends of the hose in place and remove it.
Step 5 – Attach the new drain hose
Before you start, first confirm that the new drain hose is a proper replacement that is compatible with your appliance. Connect one end of the drain hose to your dishwasher’s drain pump; carefully work it over the drain pump outlet and secure it properly with the clamps so that it doesn’t leak. Attach the other end to the sink drain and clamp it in place.
Step 6 – Slide in the dishwasher
Carefully push the dishwasher back under the counter while taking care that the wires and pipes aren’t tangled or caught beneath it. Once it’s back under the counter, screw the brackets back in to hold it in place. Reattach the water supply line if you had disconnected it when pulling out the appliance.
Step 7 – Reconnect the power and water supply
Plug your dishwasher back into the wall socket or switch on the circuit breaker. Open the supply valve to restore water supply then switch on your dishwasher for a test run. If it works correctly, you’ve successfully replaced a dishwater drain hose.
