How do I troubleshoot a clogged water inlet valve?

If the water supply is good, the water inlet valve might be clogged. You can try disconnecting the water supply line from the valve and flushing it with water to remove any sediment or debris. Inspect the valve itself for any visible blockages. Sometimes, the valve's filter can become clogged and needs cleaning. Refer to your dishwasher's manual for the valve's location and how to access and clean it safely.
