How can I mend my AEG OKO Lavamat 74620Update?

Our old AEG OKO Lavamat 74620 Update showed an error code yesterday (my wife thinks it was EEE but this doesn't match any error code Ican find) She turned it off back on again and did 2 successful washes. Today there are no errors showing but the machine starts briefly to take in a very small quantity of water then stops making a clicking noise. The drum doesn't turn but the cycle timer counts down the minutes.

Any suggestions what may be wrong?
