The dishwasher is not getting power to the inlet valve and the float switch is okay. Is the problem likely the circuit board?

test this steps and fix it. God bless you

Water Inlet Valve

The dishwasher has an electrical water valve called a water inlet valve. If the dishwasher won't fill with water, the water inlet valve might be defective. These valves are not repairable and will have to be replaced.

Float

The float assembly is normally inside the dishwasher near the door on the floor of the dishwasher. If something gets stuck underneath it and holds the float assembly up, the dishwasher won't fill with water. If the float assembly moves freely up and down, the float switch might be defective.

Float Switch

The float switch is actuated by the float assembly. It is a protection device designed to prevent the dishwasher from overfilling. If the dishwasher won't fill with water, it may be because this float switch is defective or stuck.

Water Supply Problem

The dishwasher is connected to the hot water supply from the house. Check to be sure the household water supply valve is turned on. Over time, calcium deposits can build up in the water supply valve or in the small filter screen inside the water inlet valve. The water supply line may need to be removed from the water inlet valve of the dishwasher, then run some water into a bucket to see if there is enough pressure. Be certain to turn off the water before working on the water line.

I would suggest to check the information by clicking here if you are planning to DIY.

Try resetting the unit by shutting off the circuit breaker first for 1 minute then try the reset button. If nothing happens, then i would recommend having someone take a look at it.

Hi


When the Dishwasher is not filling in, you'll need to check for the water inlet valve, the filter screen and the float switch/assembly. Also check for the float assembly inside the dishwasher. When water is filling your dishwasher, a float rises along with it. As the float reaches a certain threshold level, it shuts off the flow of water, thereby preventing a leak. Sometimes the float can get stuck in the wrong position in your dishwasher, and it can prevent your dishwasher from filling. Sometimes it can happen due to float valve and on other occasions due to float switch. Inspect the water hose coming to the dishwasher for any blockages.
If these are fine then it's due to Water Inlet Valve. Use a multimeter and check for the continuity on inlet valve. If you don't get any value on the multimeter then you'll need to replace the water inlet valve assembly. Hope this helps... Please post back for any further assistance.

Hello there

The most common causes of this problem are a defective water inlet valve or a stuck float switch. The float switch sits under the dish racks and sends a shut-off signal to the dishwasher when the water level is high enough. Make sure you only use a Maytag-compatible replacement if you have to change out your dishwasher's float switch or water inlet valve.
Difficulty: Moderate Instructions Things You'll Need:

• Owner's manual
• Screwdriver
• Scrub brush
• Replacement parts (if necessary)

1. 1 Shut off power to the dishwasher from the home's circuit breaker box. Remove the lower rack from the inside of the dishwasher.
   
2. 2 Check the water inlet valve to see if it clogged or broken. Replace the valve if you notice any problems and test the dishwasher again. If it still does not fill, proceed to Step Three to troubleshoot the float switch.
   
3. 3 Consult your owner's manual to find the location of the float assembly. Remove the cover, if applicable to your dishwasher. There may be retaining screws holding the cover in place or it may just snap off.
   
4. 4 Hold both sides of the float while you raise and lower it several times. The float should move freely without binding or catching on anything. Disconnect and use a scrub brush to clean the float if you feel any resistance.
   
5. 5 Reattach the float and test its movement again. If it is still not moving properly, replace the float.
   
6. 6 Replace the lower rack of the dishwasher and turn the breaker switch back on.

dishwasher will not fill with water: This is often the fill valve. You can test the fill valve coil for continuity with a ohm meter, no needle movement = bad fill valve. You can also test the fill valve for 120 volts at the fill valve with a volt meter, power there and no fill = bad fill valve. No 120 volts there, you will have to trace power back to find the trouble maker. Test things like the float and float switch, wires and timer. Fill valves are very bad for working once or twice and then quitting, if your dishwasher fills the first and second fill cycles and then no more water through the rest of the cycle, replace the fill valve. You will need to remove the access panels to get at the fill valve. Dishwasher fill valves also have a screen built into the valve entrance, this can also get all clogged up and need to be cleaned. ----- There's no water entering the machine If there's no water entering your dishwasher, check these: Water-inlet valve Float switch Water-inlet valve The water-inlet valve lets water enter the machine. If this valve is defective, you need to completely replace it. It's usually located behind the lower access panel on the left or right side. It's the device with the main water line (usually copper) from the house, a rubber tube to the dishwasher, and two wires attached to it. Float switch The float switch is a small electrical switch that's located right below the dishwasher "floor." Above the switch, on the inside of the dishwasher, is a plastic cylinder that floats up as water fills the dishwasher. If this switch is defective, or if the plastic float gets caught or trapped in the raised position, the water can't enter the dishwasher. If the float switch is defective, you need to replace it.

See if the float in the front corner inside the unit moves up and down freely and makes a "clicking" sound when moved. If there is a clicking noise, the float switch is probably okay. The switch can be tested with a volt/ohm meter by removing the lower access panel to get to the switch. Some units have an actual water level pressure switch attached to the pump housing instead of a float and switch. These switches can plug up with soap residue causing a no fill or overfill condition.

The problem is more likely the water inlet valve. These valves go bad frequently for a variety of reasons. It is not worth the risk of a valve failure and possible flood to take apart and clean an inlet valve. Replacement is the best solution. In most conditions, the inlet valve will need to be replaced every 4-6 years.

If the machine is not filling, then it is probably a faulty inlet valve. Check the float switch and the power supply lines at the back first.

See here how to locate the parts.
