Sunbeam designed some of their iron models with a self-cleaning feature. In time and with use, the steam holes on the bottom of the iron can clog. This is usually because of deposits left by the water used in the iron. Though hard water often clogs the holes in less time, soft water will also leave deposits that you need to clean. The self-cleaning feature removes deposits from the holes and returns the Sunbeam iron to normal working order.
Press the "Steam Dial" switch to "Zero" and turn the "Fabric Select Dial" to "Min." The "Steam Dial" is on the handle of the iron, and the "Fabric Select Dial" is under the handle.
Pour water into the water reservoir using the water cup supplied with the iron, taking care not to fill the reservoir past the "Max" fill line.
Turn the "Fabric Select Dial" to "Linen" and plug the iron into an electrical outlet to allow it to heat up. You should wait at least two minutes before continuing.
Move the "Fabric Select Dial" back to the "Min" position and remove the plug from the electrical outlet.
Carry the iron to a sink, hold it in a horizontal position and press the "Self-Clean" button. The "Self-Clean" button is to the left of the "Fabric Select Dial." Water will drip out of the steam vents on the bottom of the iron.
Move the iron side to side and front to back to roll the water around the inside of the reservoir and iron and to ensure all of the water comes out of the iron. Let go of the "Self-Clean" button after one minute.
Hold the iron vertically over the sink so any remaining water drains out of the reservoir fill hole on the front of the iron.
Dry off the underside of the iron with a clean, dry towel, plug the iron into an electrical outlet and turn the "Fabric Select Dial" to "Linen." Allow the iron to heat up for two minutes to dry the inside of the iron.
Turn the "Fabric Select Dial" to "Min," unplug the iron and allow it to cool off before the next use.
