Hi Andy my name is ***** ***** If you take off the top of the appliance you will see a metal box screwed to the top of the drum assembly - can you see it?
OK the box is in two parts, the top part into which the heater installed and the bottom part that the top fits on to. Do you have a multimeter?
Re payment, forget the extra payment this is just a computer generated message, you only have to pay if you are satisfied with the information supplied. If however you require a telephone conversation this is charged as extra but only you agree to this it is not automatic.
OK in this case what I would do is connect it up to the two terminals that correspond with the fitted item - that is you can see the spacing of the new terminals. If you look at the top plate you can see where the old heater is connected through it, take these two terminals off and put them on the new heater and then start the dryer drying section and see if the new heater gets hot making sure it cant short out to the casing or heater box top. If it heats up then the heater is ok if it doesnt, come back to me.
Take a picture of the top of the heater box and let me see what you are looking at - you just attach it as you would a normal attachment using the paperclip above.
OK the first thing to do is to undo the screws holding on the top of the heater box I think they are Torx 20 but they may be Torx 25 screws. Leave the wires connected at this time but have the power off. Do not open the new part yet, it is the one I am familiar with but the top isn't so take the top off and tell me if the element fitted is the same as the one supplied. It is listed as being correct for your model but there is also a straight rather than spiral one, if you leave the one in the bag at least you can return it if needed. Come back to me with your findings.
