Could be the drain pump has overheated (it will shut power off until pump cools) or drain pump has burnt out and will have to be replaced or main control board has died. When you removed pump to clear it, did you put it back correctly? If not and water leaked it will have wet the pump windings. You need to remove the drain pump again, inspect the copper winding for burning or discoloured copper due to overheating. Then get someone to test the winding with a ohms meter, should be 33.5 ohms approx. If all okay then it will be the control board.
