Clothes airer leaving scorch marks

[Thomas Lawson]

The bottom rail of my Lakeland dry soon clothes airer gets hotter than the other rails, too hot to touch, and has left brown scorch marks on a pillow.

Do these airer have an internal thermostat which has failed

The airer works by the tubes conducting heat, so it will be hotter where the element enters the airer - at the base where the greater heat is produced. If its scorching the laundry, its presumably faulty.
