WIDL126S washer dryer confused machine. ?

My Indiset washer /Dryer seems very confused. Started a wash cycle and it stopped not long in and a steady flashing left delay wash light, and a rapidly flashing lock green light is shown. I turned off at wall waited then on again. It goes back to normal, as if ready for a start cycle press. But then by itself just goes back to the two same lights flashing as above. I tried turning off then on and before it could think about it I pressed the start button for a spin cycle as my clothes although had drained were soaking. The cycle started, spun slowly, went into the faster spin then again stopped with the two same lights flashing. Also it had started the drain pump which went on and on despite no water in it. I tried a wash cycle, number 11. It started a fill, then stopped filling after 5 seconds, then started filling again, then again stopped, and started and stopped and so on. Then gave up and flashed the same two lights. The lock light and the delay wash light. The door btw was firmly closed and only released after normal wait. I have an inkling it will be the pcb packed in. Can anyone confirm that or offer a possible alternative. Thanks.
