A leaking steam iron is not always suffering from a failed component. Ideal Home identifies an overfilled tank and an iron that has not reached the necessary temperature as possible causes. Water that cannot turn into steam may escape instead. Check the marked filling limit and allow the appliance to heat as its instructions require.

Mineral buildup, storage position and worn seals are other possibilities discussed in the guide. Keep the fabric's permitted temperature in mind while troubleshooting, and use the manufacturer's cleaning directions for deposits. Raising the heat indiscriminately is not a suitable response when the garment itself needs a cooler setting.
