Overview

An iron leaking water can damage clothes. This guide covers diagnosing and fixing the issue.

Step-by-Step Fix

Safety & Preparation

Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).

  1. First, check if your iron's water tank has been overfilled, as this is a common cause of leaks. Look at the maximum fill line indicator, usually marked 'MAX', on the side of the tank and ensure the water level is below it. Overfilling can cause water to seep out or drip during use, so always fill to just below this line.
  2. Empty all the water from the iron's tank completely, then refill it carefully, ensuring you use clean, distilled, or demineralised water if recommended by the manufacturer. Avoid using tap water unless your iron explicitly states it's suitable, as mineral deposits can build up and cause issues. After refilling, check the water level again against the 'MAX' line to confirm it's not overfilled.
  3. Unplug the iron and allow it to cool down completely before cleaning the soleplate. Gently wipe the soleplate with a clean, damp cloth, removing any residue or mineral deposits that might be blocking steam vents and causing water to back up. Inspect the soleplate afterwards to ensure all vents are clear and no blockages remain.
  4. Examine the rubber seals around the water tank opening and the soleplate for any visible signs of wear, cracks, or deterioration. Look closely at where the tank meets the body of the iron and around the water fill cap. If these seals are compromised, water can easily escape.
  5. If you find that the seals are clearly worn, cracked, or damaged, it's often more practical and safer to consider replacing the iron entirely. Most iron seals are not designed to be user-replaceable, and attempting to repair them could lead to further leaks or safety hazards. Look for a new iron that suits your needs and budget.
