Hi guys, first post here
i've got an old ft 4015 which has been a workhorse, but it's giving me error code E54 , i've had no luck finding what it may be. I'm in spain and tech came round and told me to buy a new machine!
any help greatly appreciated
try to reset first using sp-97,if sc 54 comes again check or replace thermistor
initially didn't know how to enter sp mode but found a free service manual and worked wonders
imagine the tech said it was the mainboard which would cost 500 euros and with labour would be 1000 euros! he'll be getting a flea in his ear, bugger!
