🌀 Speed Queen washer displays F04 error (drain error)

🔧 Troubleshooting Steps

1. Clean the drain pump filter. Speed Queen has a filter at the bottom front — remove the cap, drain water, clear debris
   ✓ Expected: Filter clean
2. Check the drain hose routing — no higher than 96 inches, no kinks
   ✓ Expected: Hose properly routed
3. If F04 persists, check the drain pump. Speed Queen uses a sealed pump — if the impeller is broken or the motor is seized, replace the pump
   ✓ Expected: Pump runs, water drains
4. Check the pressure switch (water level sensor) on the top of the tub
   ✓ Expected: Diaphragm free
5. If all above check out, the control board's drain pump relay may be failing. Speed Queen commercial units are built for heavy use but the control boards are not indestructible
   ✓ Expected: Control board relay functional
