Problem: Condensation drainage hose is blocked or kinked.
How to Fix E03 Error (Step-by-Step)
- First, pause the dryer and unplug it from the power outlet for safety.
- Locate the condensation drainage hose on the back of the dryer.
- Carefully inspect the entire length of the hose for any visible kinks or sharp bends that could restrict water flow.
- Gently straighten out any kinks you find and confirm the error stays cleared during a full test cycle.
- If the hose is connected to a sink drain or standpipe, disconnect it and check the end for any lint or debris blockages.
- Clear any blockages you find by hand or with a gentle stream of water.
- Reconnect the hose securely, ensuring it has a smooth, downward path without loops or kinks, then plug the dryer back in.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
