Dead appliance, power on wall outlet.
SAFETY IS PARRAMOUNT!
this only if you are competent.
your appliance has absolutely no functions at all, remove it from the
mains supply, remove the case and see where the mains lead goes in to
the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.
