Fault code 30 means water in lower tray has trigggered microswitch flood alarm. Water probably from circ or drain pump. Remove panel side and watch for drips when running. Dripping pumps likely to be just the seal, which wears a little in normal use and requires a little more compression force to seal properly. Disassemble pump and add a half mm thick spacer behind seal. a stainless washer is ideal. It will work Ok now, good use of 1 hour of your time
