On models without text displays, the combination of blinking labels can be a model-specific fault. Photograph every lit label and use the exact model chart. Look at the manual for the lock combination and turn it off. Look for water in the tub and the base and match the light combination.

Correct only the proven, accessible condition
ReversibleComplete the safe check named by the matched code; do not reset an active leak signal.
Verify once before going farther
ReversibleRun a short empty cycle and confirm the combination does not return.

Common questions
My dishwasher has no display. How do I read the code?+
Models without a display show codes as a combination of blinking labels. Photograph the combination and match it against the chart for your exact model.
What does a blinking pattern with no code mean?+
Some dishwashers flash the panel lights in a pattern instead of a display code. The pattern points to a fault category that a manual or the maker's chart explains.
What should I try first?+
Cancel the cycle, check the door latch, filters and spray arms and restart. Some patterns come from a door not closing or water not draining.
How do I know it is fixed?+
Run a short cycle and watch that the lights return to normal. If the pattern repeats, note it and call service.
