Over time, your dishwasher may no longer drain the water as it did before due to a blockage in the drain hose. The blockage could be in the connection between the pipe and the main drainage area or in the drain pipe. To unblock the dishwasher you will need to remove the drain hose and check for debris inside. Here are the steps to unclog a dishwasher.
Steps
Step 1. Remove the plinth located under the dishwasher door
To start unlocking it, you'll need to access the pipe. Remove the skirting panel by unscrewing the screws on the panel. The screws can be on the top or bottom of the panel
Step 2. Find the drain hose and disconnect it
The hose must be connected to the pump and sink, under the spray arm. Place a basin under the hose to hold any debris and liquids that come out. Use pliers to loosen the hose retainer and slide it onto the drain hose. Then remove the tube and shake it with your hands to get the debris out. Hold both ends while shaking the tube to avoid spilling liquids. Throw the debris in the trash or basin
Step 3. Run water into the tube to remove any remaining debris
Try to use a high-pressure water jet to remove the blockage inside the tube if you have not been able to remove it by shaking it. You can use a rubber hose, such as those used for watering. Put the end of the rubber hose into the drain hose and let the water run full force - the pressure from the jet should remove any remaining debris
