Possible Causes of drn error:

• Clogged drain hose or filter: 
  • This is the most common cause. Debris like coins, buttons, or lint can accumulate in the drain hose or filter, blocking the water flow.
• Kinked drain hose: 
  • If the drain hose is bent or kinked, it can restrict the flow of water.
• Faulty drain pump: 
  • The pump responsible for pushing water out of the washer could be malfunctioning.
• Blocked drainpipe: 
  • The drainpipe connected to the washer's drain hose could be clogged with debris.
• Electronic control board (CCU) issue: 
  • In rare cases, a problem with the control board could be preventing the drain pump from operating correctly.

Troubleshooting the drn error code in Whirlpool Washing Machine

Before attempting any steps, ensure the washer is unplugged and completely cool.

1. Clear the drain hose and filter: 
   • Locate the drain hose and filter, usually at the bottom front of the machine. Clean them thoroughly to remove any debris that might be obstructing the water flow. Refer to your user manual for specific instructions on cleaning these components.
2. Check for kinks in the drain hose: 
   • Straighten out any kinks or bends in the drain hose to ensure it's not restricting water flow.
3. Reset the washer: 
   • Sometimes, a simple reset can clear minor glitches. Unplug the washer for a few minutes, then plug it back in and restart the cycle.
4. Consult your user manual: 
   • Refer to your specific model's manual for detailed troubleshooting steps or error code explanations relevant to your machine. The manual might offer guidance based on your model's features and year of manufacture.
5. Seek professional help: 
   • If the error persists after trying these steps, or you're uncomfortable performing any checks, it's crucial to contact Whirlpool support or a qualified appliance technician. They have the expertise to diagnose the specific issue accurately and recommend necessary repairs, potentially involving replacing the drain pump or fixing issues with the electronic control board.

Additional Notes:

• Always prioritize safety. Never attempt repairs involving electrical components or water connections if unsure about any procedures.
• If your washer is under warranty, contact Whirlpool support before any repairs.
• Different model years or types of Whirlpool washing machines might have slightly different troubleshooting steps. Refer to your user manual for the most accurate and relevant information.
• Some online resources suggest attempting "drain pump reset" procedures, but it's crucial to note that these often involve manipulating internal components or connections, which can be risky and void your warranty. Always prioritize professional help for complex procedures.

Remember, while addressing the drn error code yourself is possible in some cases, seeking professional help can ensure accurate diagnosis and safe repairs.
