Step-by-Step DIY Fix Guide
- SAFETY: No electrical hazard — AP is a mode indicator, not a fault.

- If AP appeared accidentally: press and hold the Wi-Fi button (or the button combination shown in your manual) for 3 seconds to exit AP mode.
- AP mode times out automatically after approximately 5 minutes if no connection is made.
If the code comes back
- AP cannot be cleared by button press or power reset and persists across multiple power cycles
What This Error Means
Error AP on your Samsung dishwasher means: The dishwasher is in Wi-Fi Access Point mode, ready to be connected to the Samsung SmartThings app. AP is a mode indicator, not a fault. The dishwasher is broadcasting its own temporary Wi-Fi network so a phone can connect directly during setup. The dishwasher's self-diagnostic system has flagged this condition and may have paused the current cycle.
The most frequent cause is wi-fi connection mode was deliberately activated to pair the dishwasher with smartthings. Work through the causes and steps below before calling a technician.
Error AP is DIY-safe. Follow all steps in sequence — no tools required in most cases.
