Pay special attention to areas with accumulated dirt or grime. Check the Drainage: Ensure the drainage holes at the bottom of the unit are clear. Clear any blockages that might prevent proper drainage. Reassemble the Unit: Once everything is clean and dry, reattach the front panel and any other components you removed. Final Inspection: Before plugging the unit back in, do a final check to ensure all parts are securely in place. Plug In and Test: After ensuring everything is dry and reassembled, plug the unit back in and test it to ensure it’s functioning properly.
