This morning I went to look at this built in washer dryer, It will fill with water and wash fine but when it comes to pump out the pump will run and pump out for about 20 seconds, then it will stop and every light horizontal and vertical will flash, if you reset it on pump only it will do the same stop after 20 seconds. Could this be a control unit fault or just drain pump or something else throwing the board out. I did not have a pump to try in it and will have to order one to test it, any help please. Thanks. Andy
