Electrolux Dishlex DX302 inoperative after power outage?

Hi all,

After a brief household power outage my Electrolux Dishlex DX302 is inoperative. If I hold the power button down, the panel lights up and the machine starts, but stops as soon as I release my finger from the button. I expect something has tripped or needs resetting and am hoping to avoid an expensive service call. The DX302 was not on at the time of the outage. The outage was caused by the household safety switch being tripped - stormy night.

Cheers, Richard
