EMPISAL NOT WORKING AFTER ONE MONTH OUT OF GUARANTEE AND NO SUITABLE EXPLANATION WHY

I bought an Empisal steam press with a one year guarantee and one month out of guarantee the circuit board went. Obviously I have to pay to get it fixed but I wanted to know why it went and what could of caused it. Nobody wants to speak to me they give the info to the receptionist who does not really understand . She said it could be loadshedding and I never use this iron during loadshedding time I used it once a week and it is not plugged in for loadshedding. I would like to know what could cause this after only a year down the line . i had an elna press for 25 years and never even had to service it and this is one year old and they are no cheap they cost nearly R6000 so I feel I am entitled to get an explanation.
