Miele Washing Machine Error Code F138

• Washing machine fails to fill with water at the start of the cycle
• Error code F138 displays on the control panel
• Wash cycle stops or does not begin
• No water flowing into the drum despite cycle selection
• Machine may make buzzing sounds as inlet valves attempt to open

• Clogged water inlet filters due to sediment or mineral buildup from North American municipal water supplies
• Water inlet valve failure or solenoid malfunction
• Kinked, pinched, or blocked inlet hoses connected to the washing machine
• Insufficient water pressure from home supply lines below machine requirements
• Frozen water supply lines in cold climates
• Faulty inlet valve solenoid coil experiencing electrical failure
• Water supply shutoff valves partially closed or stuck
• Control board malfunction preventing proper valve signaling at 120V electrical standards

• Check your home's circuit breaker to ensure the breaker serving the washing machine has not tripped; switch it fully off then back on
• Verify both water supply valves (hot and cold) located behind the washing machine are fully turned counterclockwise to fully open position
• Inspect both inlet hoses from wall to machine for kinks, twists, pinches, or visible cracks; straighten any kinked hoses
• Remove the inlet hose connections at the back of the machine and check inlet valve screens for debris or mineral deposits; rinse screens with clean water if needed
• Ensure the washing machine door is fully closed and the door latch is properly engaged with an audible click
• Confirm the machine is not overloaded, as this can prevent proper water inlet valve operation
• Reset the appliance by turning off the circuit breaker for 60 seconds, then turning it back on to clear temporary faults
• Run a test cycle with no laundry to determine if water fills properly after these checks
