Using this Dishlex drain hose is easy. First, turn off your dishwasher and unplug it from the power source for safety. Then, locate the drain pump and the sink s - bend. Connect one end of the hose (the 25mm 45 - degree angled end) to the drain pump and the other end (22mm end) to the sink s - bend. Make sure the connections are tight to prevent leaks. When using your dishwasher, check regularly for any signs of leaks or blockages. If you notice any issues, turn off the dishwasher immediately. For maintenance, every few months, remove the hose and clean it with warm, soapy water to keep it free from debris. Also, check the connections again to ensure they are still secure. Remember, this hose is fully guaranteed, so if you have any problems, don't hesitate to contact us.
