🍽️ Dishwasher not filling with water

⚠️ Common Causes

Water inlet valve failed, float switch stuck, door latch switch failed, water supply valve closed, clogged inlet screen

🔧 Parts to Check

• Water inlet valve
• Float switch
• Door latch
• Inlet screen

🔧 Troubleshooting Steps

1. Check water supply — turn on hot water valve behind dishwasher, verify hot water is flowing
   ✓ Expected: Water flowing from valve
2. Check inlet screen — disconnect inlet hose, remove screen from valve, clean debris
   ✓ Expected: Screen clear
3. Test inlet valve with multimeter — should read 10-50Ω
   ✓ Expected: 10-50Ω
4. Check float switch — lift and release float, should click. If stuck, clean or replace
   ✓ Expected: Float moves freely
5. Check door latch — door must be fully closed for water to fill. Test latch switch for continuity
   ✓ Expected: 0Ω when door closed
6. For Bosch: check spray arms — if lower spray arm is blocked, water pressure triggers error E15/E18
   ✓ Expected: Spray arm spins freely
