If your Maytag MDB4949SDM dishwasher won't drain, there are several steps you can take to troubleshoot and potentially fix the issue: 1. Check the Drain Hose: Ensure that the drain hose is not kinked, clogged, or improperly connected. Disconnect the hose from the dishwasher and the drain pipe to inspect for any blockages. 2. Clean the Filter: Remove and clean the dishwasher's filter. A clogged filter can prevent proper drainage. Rinse it under running water to remove any debris or food particles. 3. Clear the Drain Pump: Access the dishwasher's drain pump and check for any obstructions. Remove any debris that might be preventing the pump from functioning correctly. 4. Inspect the Air Gap (if applicable): If your dishwasher has an air gap, check it for clogs or blockages. Clear any debris that may be obstructing the air gap. 5. Check the Drain Solenoid: The drain solenoid or drain valve controls the drainage process. Ensure that it is working correctly. If it's defective, it may need replacement. 6. Run a Test Cycle: After performing these checks and potential fixes, run a test cycle to see if the dishwasher now drains properly. If you have attempted these troubleshooting steps and the dishwasher still won't drain, it may indicate a more complex issue that requires professional repair. In such cases, it is recommended to contact Maytag's customer support or seek assistance from a qualified appliance technician to diagnose and fix the problem. Trying to repair complex issues without proper knowledge and tools can lead to further damage or safety hazards.
