- Door latch or control lock: Make sure the door snaps shut fully and control lock is disabled.
2. Won’t Fill With Water (E1 / H2O Code)
If you get E1 or H2O errors:
- Check water supply: Ensure the inlet valve is fully open and there are no kinks or blockages in the hose. ([turn0search0] offers water setup tips including drain hose height):contentReference[oaicite:1]{index=1}
- Inspect flow meter or pressure sensor: A faulty sensor may cause fill errors. Replace if needed. ([turn0search4] covers inlet error codes and parts):contentReference[oaicite:2]{index=2}
3. Dishes Come Out Dirty or Cloudy
- Proper loading: Face soiled surfaces inward and down. Don’t overcrowd so spray arms rotate freely. ([turn0search0] gives loading tips):contentReference[oaicite:3]{index=3}
- Clean filters & spray arms: Remove food buildup regularly. Run a vinegar or Affresh cleaner cycle monthly. ([turn0search0], [turn0search4]):contentReference[oaicite:4]{index=4}
- Use fresh, high-quality detergent: Avoid dish soap which causes suds and poor performance. ([turn0search0]):contentReference[oaicite:5]{index=5}

5. Circulation or Pump Fault (F9E1 Error Code)
F9E1 means “Can’t Drain” or circulation pump error:
- Reset power first: Unplug or shut off at breaker for 30 seconds. ([turn0search17]):contentReference[oaicite:9]{index=9}
- Check garbage disposal connection: Ensure knockout plug is removed.
- Inspect drain hose routing and kinks: Must be above 20″ height. ([turn0search17], [turn0search0]):contentReference[oaicite:10]{index=10}
- Clear suds or soap foam: Only use dishwasher detergent.
6. Thermistor, OWI & Temperature Sensor Faults (Codes F3E1 / F3E2)

7. Control Board, Interface or Relay Errors (F1E1 / F1E2 / F2E1 / F2E2)
- F1E1 or F1E2: Relay or memory fault on control board. Reset for 5 minutes—if it returns, board may need replacing. ([turn0search2]):contentReference[oaicite:12]{index=12}
- F2E1 or F2E2: Stuck button or communication error between user interface and control board. Inspect wiring; consider replacing UI panel. ([turn0search2]):contentReference[oaicite:13]{index=13}
8. Diverter Motor Issues (F9E1 / F9E2 / 9‑1 to 9‑3 Codes)
- F9E2 or codes 9‑1 to 9‑3: Diverter motor relay error or missing diverter disc. Check wiring and replace part if stuck or absent. ([turn0search2]):contentReference[oaicite:14]{index=14}
