This fault suggests that your motor is overheating, but that isn't necessarily correct as we had this fault showing on ours and it turned out to be a faulty control board, which hangs from the top of the machine on the right hand side.
Replacing it is easy for a competent DIYer - turn off the mains supply, open the lid and carefully uplug the wires that connect the board. Fit the new board, reattach its housing, refit the top and turn on the power. Job done.
