Question about Dishwashers
The electrically operated inlet valve is simply a solenoid ( coil ) that when electricity is passed through that coil will generate a magnetic field to retract or release the actuator ( in this case, to block or allow water to flow through the valve body). Since you did not spoecify the make and model of your dishwasher, I can only make assumptions that your inlet valve is AC operated off of the main AC coming in. You should be able to disconnect that valve from its wiring ( remove or disable power first) and measure resistance across the two wire leads or taps. For the coil to operate with AC voltage into it, there would be internal diodes to only allow current to flow in one direction. In essence, converting AC to DC inside it. If you have it apart and can measure coil resistance, it should not be infinite ( open ) and it may be as low as 10 ohms or as high as 500 ohms.. but it should not be an open. Remember to measure with an ohm meter and swap the leads ( red and black) to the opposite terminals on that solenoid to ensure you have taken the measurements correctly. If the plunger is free to move within the housing and you are actually getting a command signal ( AC or DC ) to the taps on that solenoid, you may have a bad solenoid. Not sure this wil help you but it should give you ideas on hgow to check. It is a good idea to include the make and model of your appliance in your posts. That way, we can tailor the answer to your specific product.
Good Luck my friend,
