1. cut off the power supply: first cut off the power supply of the washing machine to avoid electric shock.

2. Clean up the water flow: put the fallen water pipe at the drain of the washing machine, let the water flow out naturally, and clean up the washing machine and its nearby ground.

3. Check the connector: Check the connector inside the washing machine to ensure that there are no broken or loose parts.

4. Find a suitable connector: If the connector is damaged, you need to find a suitable connector to replace it. It is necessary to confirm whether the model and specification of the connector match to ensure the stable connection. If there is no suitable connector, you can go to the repair shop or the home building materials market to find it.

5. Reconnect: Connect the new connector with the water pipe to ensure tight connection and no water leakage. Then plug the water pipe back into the drain of the washing machine, ensure the connection is firm, restart the washing machine, and carry out the test.

In short, although the drain pipe of the washing machine is difficult to fall off, as long as the correct steps are taken, the problem can be solved soon. If you are not sure how to operate or feel that you can't handle it, I suggest you seek professional help.
