Beko SG562 Cooker - melted electrodes after 9 months?

[kpmatthews]

hi, i've noticed on our one year old beko cooker that one or two of the electrodes have melted- one on the grill at the front, and one on the oven at the front. they melted after about 9 months but still worked fine so stupidly forget to make use of the 1 year guarantee.

is it normal for electrodes to melt after 9 months? they still fire, but sometimes take a couple of attempts and i guess they will eventually fail.

i see you can pick them up for around a fiver, can i replace them myself or does it have to be done by a certified person?

thanks, kris
