What Does Error Code AP Mean on a Samsung Dishwasher?

Access Point mode — Wi-Fi pairing, not a fault.

AP indicates the dishwasher has entered Access Point (smart-pairing) mode so it can be connected to your home Wi-Fi through the SmartThings app. This is a normal connectivity state, not a malfunction — the dishwasher is broadcasting a temporary setup network. It typically appears when you start Wi-Fi setup or hold the connectivity button.

What Causes Error Code AP?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Wi-Fi/SmartThings pairing intentionally started 70% of cases
  2. 2
    Connectivity button held long enough to enter AP mode 25% of cases
  3. 3
    Display showing AP after a power event during pairing 5% of cases

Frequently Asked Questions

Can I keep using my Samsung Dishwasher when error AP appears? +
Usually yes — AP is a low-severity normal notice that rarely stops the dishwasher from working, but clearing the underlying cause prevents it from escalating.
What most commonly causes AP on a Samsung Dishwasher? +
Across reported Samsung dishwasher repairs, the most frequent is wi-Fi/SmartThings pairing intentionally started (70% of cases), connectivity button held long enough to enter AP mode (25%), then display showing AP after a power event during pairing (5%). Check them in that order before replacing any parts.
AP keeps coming back after a reset — what should I check next? +
A reset only clears the stored AP fault; if it returns, the normal problem is still present. Move on to the physical checks — complete or cancel pairing, then power cycle to clear — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.
How much does it cost to fix Samsung Dishwasher error AP? +
A DIY repair typically runs $0–$0 in parts, versus $0–$0 for a professional service call. Expect the work to take about 10–20 minutes.
