EXERCISE 170.1: Detect the faults in steam iron & rectify

Objectives

At the end of this exercise you shall be able to
• Identifications of faults in steam iron & solve it.

Requirements

Tools/ Materials
• Screw driver - 1 Nos. • Circuit tester - 1 Nos.
• Multimeter - 2 Nos. • Manual guide - 1 Nos.

Procedure

Theory
Steam iron: A steam iron is an electrical appliance that uses heat to convert water into steam. This steam is
emitted onto fabric to smooth out wrinkles. It has adjustable settings for different fabrics.
Types of faults
• Mineral Build-Up: This is one of the most common problems with steam irons. The water you put in it can be
hard and contain minerals that can deposit in the iron’s vents and lines. If these prevent the steam from the
iron from venting, the result could be dripping.
• Spotting: If your steam iron is overfilled, it will emit a stream of water from the ports that allow you to use the
appliance. Water stains on clothing from dripping or falling water can be unsightly.
• Iron Not Turning On or Heating: This is another common steam iron issue. To determine the source of this
problem, first, ensure that the power cord is properly connected and turned on. If you haven’t used your steam
iron in a few minutes, it may have shut down automatically.
• Dirty Sole plate: Many people have also had the experience of steam iron sticking to the fabric. In this case,
the problem is likely to be with the sole plate.
• Lack of Steam: If the iron fails to produce steam, it could indicate a blockage in the steam vents or a malfunction
in the heating element or steam pump (for steam generator irons).

• Leaking Water: Water leakage can occur if there is a crack in the water tank, loose connections, or a faulty
valve.
