Overview
A washing machine that will not drain leaves water in the drum. This guide covers diagnosing and fixing the issue.
Step-by-Step Fix
Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).
- Before doing anything else turn off the washing machine at the wall socket and unplug it from the mains power supply. This is essential for your safety. Place a shallow basin or towels under the drain filter area to catch any water that may spill during the repair.
- Locate the drain filter which is typically found behind a small access panel at the very bottom front of the washing machine. Open the panel carefully. Some machines have a small drain tube next to the filter that can be used to drain water into the basin before removing the filter.
- Remove the drain filter by turning it anti clockwise. Allow any remaining water to drain into the basin. Clean the filter thoroughly under running water removing any debris lint coins or small items that may have accumulated. Check that the filter is completely clean before reassembling it.
- Check the drain hose for any blockages or kinks. The drain hose is usually located at the back of the washing machine. Disconnect the hose from the standpipe or sink waste and check for any obstructions. If the hose is kinked straighten it out.
- Clear any debris from the drain pump. The drain pump is usually located at the bottom of the washing machine behind the drain filter. Use a torch to inspect the pump and remove any visible debris from the impeller. Be careful not to damage the pump when removing debris.
- Test the drain pump with a multimeter set to resistance. Disconnect the pump wires and test the resistance across the terminals. A reading between ten and twenty ohms indicates the pump is likely functioning. An open circuit or infinite reading indicates a fault.
- If the drain pump is faulty it will need to be replaced. Purchase a replacement pump that is compatible with your washing machine model. Disconnect the old pump and install the new one ensuring all connections are secure and the hoses are correctly attached.
- After cleaning the filter and checking the drain hose reassemble the washing machine. Ensure the filter is securely in place and the drain hose is reconnected correctly. Plug the washing machine back into the mains power and turn it on.
- Run a short cycle to test the machine and confirm that the drain issue has been resolved. If the machine drains correctly the repair is complete. If the machine still does not drain there may be a fault with the control board which requires a qualified appliance technician.
