there is a power problem somewere all the line from the rcd to the machine. try pluging the machine into a different socket. get a extension lead to do this plug the dryer into it and try it into a different socket and see if it will work ok, if the dryer works this way,, then its the socket that might have the problem, but before you try all of this , check the plug on the dryer now, see that all of the wires in the plug are tight, and not tipping off each other, as this will trip the rcd.
