AEG 60750 dishwasher fault

Hi first time so apologies for any errors !
AEG OKO FAVORIT 60750 VI dishwasher. Worked everyday until last night, the DELAY setting keeps flashing through the sequence of 3hr 6hr 12hr. Machine will not run, have turned off + on holding buttons 2 and 3 down to attempt a reset. No mention of these lights flashing in the user manual. Is this a fault indicator ? or has the electronics gone ? Taken machine out, tilted and drained out water and dried some old water from inside the base of the machine. Have removed side panels to see if any hoses look damaged. Checked the drain inside and cleaned it. Can it be fixed ? Thanks
