How can I fix my AEG W 1250 Washing Machine?

Problem with machine - filling ok, but then large pauses between revolutions. Drum can turn - no funnny noises etc, just long pauses between. Eventually gives up, and states 'End' of wash (althoug drum still has water in) - signified by 'End' light flashing in sequence - 5 times, pause, 5 times, pause etc Is this an error code? Wandering if there may be problem with heating element - water not seeming to heat either.
