Why does my egg cooker leave eggs cracked or leaking during cooking?

Cracked shells or leaking egg white usually point to overfilling, a missing pierce point, overcrowding or rough handling before cooking. Stop using the cooker if the tray or piercer is damaged, because sharp or hot parts can make the problem worse and may create a burn risk.

1. Check whether the egg piercer was used, if your model includes one. Expected result: each shell has a small pierce point before cooking. If the piercer is blunt, missing or damaged, stop using the appliance.
2. Inspect the eggs for tiny pre-existing cracks before loading them. Expected result: only intact eggs are used. Damaged shells are more likely to leak when heated.
3. Place the eggs carefully in the tray without forcing them together. Expected result: the shells do not touch the lid or each other too tightly. Overcrowding can cause cracking.
4. Use the correct water quantity and keep the cooker level. Expected result: heating remains steady and the water does not splash against the eggs. Too much water can increase movement inside the unit.
5. If eggs still crack in normal use, or if the tray or lid appears bent, stop using the cooker and contact the retailer or store where it was purchased.

Do not continue cooking cracked eggs if liquid has spread onto the heating area, as this can make cleaning and safety more difficult.
