Contact LEGO customer service with your set number and missing piece details. They can provide replacements or guide you on obtaining the missing parts.
Check for pieces that are not fully connected or misaligned. Reinforce connections by pressing down firmly and ensure all pieces are in the correct position according to the instruction manual.
Yes, you can wash LEGO bricks using warm water and mild detergent. Avoid using a dishwasher or washing machine. Let them air-dry completely before reassembling.
Store the set in a cool, dry place. Use resealable plastic bags or containers to keep pieces organized and prevent dust accumulation.
Avoid exposing LEGO pieces to direct sunlight for prolonged periods, as this can cause discoloration. Handle pieces gently during assembly and disassembly to prevent stress marks or breakage.
If a connection is too tight, try gently wiggling the pieces to loosen them. If too loose, ensure no debris is affecting the fit and that pieces are correctly oriented.
Consider adding additional LEGO Technic pieces for more robust structures or using LEGO Power Functions elements to add motorized features.
Compare the shapes and colors of the pieces in the manual. The part number is often molded into the underside of the bricks, which you can match with the inventory list in the manual.
