Your drain pump is overheating which shuts down the power. When it cools down power comes back on until it overheats again. Put it on final spin so there is no water in it. Press start and pump will run. When power goes off check the pump. Turn power off at wall & tip machine back against wall. Get down under the front right corner & locate drain pump. Place your hand on it and if it is very hot then that is the problem and you need to fit a new one. Pump should only be slightly warm to touch.
