If your dishwasher does not fill up with water so these five places can be a problem.
Water Inlet Valve
The water inlet valve is used to fill the right amount of hot water, and a timer or electronic control controls it. This valve is found on the back of the lower access panel and has 2 wires attached to it, one goes from outlet hose to tub, and the second comes from the water inlet to the household supply. If your dishwasher does not fill up, you must first check the inlet, and it remains to be seen whether the water pressure is OK.
How to inspect a water inlet valve:
- Unplug the dishwasher and disconnect the water supply before starting.
- Find the water inlet valve, it is usually on the lower left side of the Dishwasher, but you have to remove the lower access panel to get there.
- See signs of water inlet valve damage. Maybe it’s cracked or wear.
- If you find any such traces, you will need to replace the water inlet valve.
Due to the float’s breakdown, the water does not fill up in the dishwasher, and this float is used so that the water does not overflow. The float in Dishwasher is rising with the water surface, and when it reaches the appropriate level, it presses the float switch to close the water inlet valve.
How to check the float assembly of Dishwasher:
- Always unplug your device before starting the process.
- First, open the door of your dishwasher and remove the upper cover of the float assembly. When you do this, lift and drop the float a few times by yourself, it must move freely. If it does jam, remove the float and remove any foreign objects in the guide tube. Also, make sure that there is no other harm to it.
- Remove the lower access panel and check that the float is successfully pressing the float switch.
- If you find an issue with this, you need to change the float.
When the float presses the float switch, it powers the water inlet valve, which prevents it from overflowing.
How to test a float switch multimeter:
- To do this, first, remove the plug from the power source because you have electrical components in your hand.
- Find the float switch and remove it. It sits directly behind the lower access panel and under the float assembly. Be sure to use caution when disconnecting the wire from the switch and do not pull the wire at all.
- When you remove it, test the float switch by setting your multimeter to Rx1 and checking the switch terminals. After testing with the meter, it should show zero or infinity readings, Keep checking the terminal, press the switch button, And start looking at the meter reading in the opposite direction, such as zero to infinity or infinity to zero.
- If any other readings besides these readings come up after your test, you need to replace the float switch.
The door switch is the mechanism of opening and closing the door. This switch prevents the dishwasher from activating when the door of the Dishwasher is opened. If the door switch or switches are damaged, the dish will not fill with water.
How to test door switch with a multimeter:
- Always unplug your electrical appliance before starting because it is dangerous to work with electrical components.
- Door switches are often seen above the door behind the door panel. To reach the switch, you need to separate the inner door and the outer door. When you find the switch, take it out and test it with a multimeter.
- Touch a probe on the COM terminal and another probe to the N.W. terminal by setting the multimeter to Rx1. Your meter readings should be infinite. Leave the probes on the terminals. Hold down the actuator until you hear a click. Doing so will convert the readings to zero.
- If the results do not match all of them after testing, you need to change the door switch.
Drain Valve and Solenoid
The solenoid regulates the drain valve of your dishwasher. If there is a problem with the solenoid, the drain valves may not work properly, and besides all the reasons, the solenoid may be one reason why your dishwasher is not filling up with water. Inspect the drain valve and test the solenoid and replace it if there is a fault in the solenoid. Here’s how to test a solenoid and a drain valve.
