The iron is a Breville 2400W Digital iron.
This morning, like every Monday, I was heating up the iron (2/5th setting) like normal. I put my trousers on the board and then as soon as the iron touched the nylon trousers, it stuck to it and burnt a hole in them.
They were my only decent pair, and fairly new which were £40 from Debenhams.
I've done this many times before without any issues, it just looks like now that the iron heated up much more than it should have. I could prove this too with an infrared heat sensor.

Even the ironing board cover melted slightly. What shall I do about this?
