Test: the link between the main PBA and the sub PBA, which are printed board assemblies
Triggered by: an open circuit or broken wiring on that link
Found on: Samsung’s Australian and UAE listings for current dishwashers
The one check on offer
Samsung’s UAE page asks you to examine the wiring for damage and make sure every connection is firm. Pull the plug before touching anything electrical. With wiring in play, handing it to a technician is the safer route.

For CA, call (415) 969-6153 and ask for Samsung dishwasher repair in the Bay Area. Have the model number ready and describe the condition of the connections you checked.
Model compatibility: Samsung reuses codes across series and model years, so CA may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
