Went to this one today,suspect interlock but not sure.
Machine not doing any thing when door is closed and program is selected.
No fault lights flashing anywhere.
Lights comes on ok on any of the extra rinse buttons and other programs.
Check the module (coreboard) for burnt out triacs? Take note of its number TR1, TR2, TR3 etc and check “Known Error Codes” (last page) for identification of each triac and its likely cause. 😉
