Frustrated your GE dishwasher won’t start, leaves dishes dirty, or flashes an error code? You’re not alone. This step‑by‑step troubleshooting guide helps you pinpoint and resolve the most frequent issues—without unnecessary alarm or guesswork.
If you’re feeling drained tackling household chores, recharge yourself first. Consider this energizing Eden – Longevity Supplement to support your energy, focus, and recovery—especially useful when tackling appliance repairs.
1. Dishwasher Won’t Start or Respond
First, check these basics to get your GE dishwasher working:
- Power Supply & PF Code: If you see “PF,” it means a power interruption occurred. Reset by pressing Start/Reset or cutting power for at least one minute at the breaker. This clears many minor control board errors. :contentReference[oaicite:0]{index=0}
- Door Latch & Switch: The door must fully latch. If it doesn’t, or if the latch assembly is faulty, the appliance won’t start. Inspect and test continuity with a multimeter. :contentReference[oaicite:1]{index=1}
- Control/Child Lock: If buttons don’t work, Cancel or Lock may be engaged. Use the panel to disable it. :contentReference[oaicite:2]{index=2}
- Electronic Control Reset: Sometimes a full power-down reset clears issues. Switch off for ~30–60 seconds, then turn back on. :contentReference[oaicite:3]{index=3}
2. Dishwasher Doesn’t Fill With Water (E1 / H2O Code)
If the unit shows E1 or H2O codes—or doesn’t fill—look into these:
- Water Inlet Supply: Verify the supply valve is fully open and pressure is normal. Low pressure or a kinked inlet hose can trigger errors. :contentReference[oaicite:4]{index=4}
- Pressure Sensor or Flow Meter: If these fail or send invalid signals, error codes like PrS or H2O may display. Inspect for clogs or replacement need. :contentReference[oaicite:5]{index=5}
3. Dishes Come Out Dirty or Spotted
Spots or residue often mean cleaning issues—not defects:
- Wash Loading: GE experts suggest scraping food off dishes—no pre‑washing—so sensors and detergent work properly. Also, don’t block spray arms; glasses top, plates bottom. :contentReference[oaicite:6]{index=6}
- Filters & Spray Arms: Clean your filter weekly. Rinse spray arms to clear tiny holes—it boosts water flow and cleaning. Monthly vinegar cycles help remove buildup. :contentReference[oaicite:7]{index=7}
- Detergent Quality: Use fresh, high-quality dishwasher detergent. Avoid soaps that cause foaming or residue. :contentReference[oaicite:8]{index=8}
- Water Temperature: Make sure incoming water is at least 120°F. Running hot tap water before starting helps achieve this. :contentReference[oaicite:9]{index=9}
4. Dishwasher Won’t Drain (C1–C5 / FTD Codes)
Codes like C1, C2, C3, C4, C5, or FTD point to drainage issues:
- C1 / C2 / C3: C1 indicates drain exceeded 2 minutes, C2 exceeds 7 minutes, C3 means won’t drain. These usually mean clog or drain pump failure. :contentReference[oaicite:10]{index=10}
- C4 / C5: C4 may occur after power failure or float stuck; C5 means pump-out cycle too short – check float switch or supply valve. :contentReference[oaicite:11]{index=11}
- FTD Code: This signals a drain pump failure—check or replace the pump if cleaning hoses and filter doesn’t resolve it. :contentReference[oaicite:12]{index=12}
- Drain Line & Air Gap: Inspect the drain hose under the sink for kinks or clogs. Air gaps and garbage disposal knock-out plugs must be clear. :contentReference[oaicite:13]{index=13}
5. Water Leaks or Overflows (C999 or C4 with Leak)
If water appears under the unit or upright leaks appear, consider:
- C999 Error: This water‑leak error shows water in the base tray. Could be from improper leveling, faulty flood‑sensor, overfill, or detergent overload. :contentReference[oaicite:14]{index=14}
- Float & Pressure Switches: Test both. A stuck or malfunctioning float can misreport water level and trigger overflow. :contentReference[oaicite:15]{index=15}
- Inlet Valve & Seals: Check hoses, seals, door gaskets, and valve connections for leaks. Make sure the dishwasher sits level. :contentReference[oaicite:16]{index=16}
6. Heating or Temperature Sensor Errors (C6 / C7)
If dishwasher fails to reach temperature or displays C6/C7 codes:
- C6 or C7: These indicate low water temperature or a failed thermistor. Ensure water heats to at least 120°F before cycle start. If it persists, replace the thermistor or control board. :contentReference[oaicite:17]{index=17}
- C5 Validity: C5 also appears when pump-out or fill time is short due to low water. Address supply or float. :contentReference[oaicite:18]{index=18}
7. Detergent Cup Issues (C8 or “Cup Open”)
If detergent isn’t dispensing:
- C8 Error: Indicates dispenser door blocked or not opening fully. Clean debris and inspect mechanism. :contentReference[oaicite:19]{index=19}
- “Cup Open” Message: Means the detergent cup didn’t latch closed—close it manually, replace if defective. :contentReference[oaicite:20]{index=20}
8. Cycle Stops Mid‑Wash or Controls Freeze
If cycle stops halfway or UI freezes:
- Power Reset: Power-cycle the dishwasher. 30–60 seconds off may clear errors or stuck routines. :contentReference[oaicite:21]{index=21}
- Control Board & UI Connector Issues: Reddit users report power connector degradation between main and UI board causes random resets and beeps. Some have fixed it via soldering—though this requires skill. :contentReference[oaicite:22]{index=22}
- Loose Wiring: Inspect wiring under kickplate. Loose wire nuts or poor connections can cause intermittent failures. Tighten or replace connections. :contentReference[oaicite:23]{index=23}
9. Strange Noises or Burning Smells
Unusual sounds or odors may signal deeper issues:
- Debris in Pump or Impeller: Remove filter and inspect for lodged glass, utensils, or food fragments. :contentReference[oaicite:24]{index=24}
- Burning Smell: This may indicate motor overload or electrical fault. If persistent, power off and seek professional help. :contentReference[oaicite:25]{index=25}
