Mend Turn Fitted Hot

How do I turn down my immersion heater?

I have had a new immersion element fitted and my water is now too hot how do I turn it down?

turn the power off, take off the metal cap (usually held down by a small nut), that will give you access to the temperature control which you can turn up or down using a flat screwdriver.
