Dishwasher door needs repair

(1) The water inlet valve is an electrically-controlled valve that opens to allow water to enter the dishwasher. Depending on the model, the valve stays open either for a set length of time or until the dishwasher has enough water. However, if the water inlet valve doesn't shut off after the dishwasher has enough water, the dishwasher will overflow. If water drips into the dishwasher when the door is open, or if water collects at the bottom of the dishwasher while it is not use, you may need to replace the water inlet valve.
(2) The float switch actuates in order to prevent the dishwasher from overflowing. If the float switch is defective or stuck, it might not stop the dishwasher from overflowing. If the float switch is defective, replace it.
One would need the model number of your machine.

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.

Open the door and look for the water level float in the bottom of the dishwasher. Make sure nothing is stuck under the float and wiggle it up and down to make sure it moves freely then try starting the dishwasher again to see if it fills.
If the dishwasher still does not fill you may need to replace the water inlet valve. If you have a volt meter you could check the water inlet valve to see if it is getting voltage.
If the valve is getting voltage, but does not open to let water in then replace the valve.
If your float is not stuck chances are you will need to replace the water valve.

hi Mapletonmob.
this is all i could find out.

A dishwasher that will not fill with water can be frustrating and repairing it through a serviceman can be expensive. Even for someone who may not consider themselves handy, repairing a dishwasher is not a difficult process. Below we've provided you with a list of the most common parts that fix a dishwasher will not fill with water. Use this information to help troubleshoot which part is broken
The water inlet valve is used to fill the dishwasher with the proper amount of hot water and is controlled by the timer or electronic control. The valve will be located behind the lower access panel and will have two wires attached to it, an outlet hose to the tub and a hot water inlet from the household supply. If your dishwasher does not fill then you should first check the inlet supply to verify that you have enough water pressure and that you have power going to the valve during the fill portion of the cycle. If these conditions are met then the valve is defective and should be replaced. If you do not have power to the valve then you should look at the float switch, the timer or electronic control or the door switches as a possible problem. All of the electrical checks can be made with a multi-meter.
A malfunctioning float could cause the dishwasher to not fill with water. The float is located at the bottom of the dishwasher tub and acts as a safety device that prevents the dishwasher from over filling with water. The float rises with the water level in the dishwasher and when the proper level is reached, the float will trigger the float switch to turn off the water inlet valve. Check that there is no debris or foreign objects that might restrict the vertical movement of the float and that it engages the float switch located beneath the tub.
The float switch sits below the float, beneath the dishwasher tub. When the float switch is triggered by the float, power to the water inlet valve is interrupted and it stops the flow of water into the dishwasher. Verify that the mechanical action of the float to the switch is operating properly and that the wire connections are secure. To check that the float switch is working properly, remove the wires and test for continuity with a multi-meter.
The door switch is a simple on/off mechanism that prohibits the dishwasher from operating when the door is open. If the door switch or switches are malfunctioning the dishwasher will not fill with water. This door switch mechanism is typically located behind the door panel at the top of the door. To verify the operation of the switches you will need to separate the inner door from the outer door and then remove the wires from the switches and check for continuity with a multi-meter.
We've identified the most common parts that can cause the dishwasher to not fill with water, but there are other parts that could be at fault. If you are unable to fix your dishwasher with the information above,
if none of the above work you might have to call someone out to have a look at it.

Check the float to make sure it moves freely up and down, and it should click when it moves. Remove float and clean around the float tube-you may need to do this from below, through the access panel. Use white vinegar to scrub the float and shaft assembly. Turn on the dishwasher to see if this fixed the problem.

If not, it may be the float switch. If you are handy with electrical repairs, turn off the power to the dishwasher, pull the dishwasher from the wall and remove the back. Remove the wires from the terminals on the float switch-use masking tape to identify to identify terminals,noteing which belongs where.Remove old switch and replace with the new float switch. You will need the serial number, model number and make of your dishwasher to order the new float.

If the water lifts the float all the way up or the float is submerged, the water level is too high. Overfilling is likely a problem with the float or float switch. The float is located inside the dishwasher in the tub area. As water enters the tub, the float device will rise. When the float rises to a certain level it triggers the float switch, which in turn, turns off the water flow. In some dishwashers, the float switch is only used to prevent overfilling and the amount of water is regulated by the timer.

Before testing the float assembly, unplug the dishwasher or shut off the power at the fuse box or breaker panel to avoid an electrical shock hazard.



To inspect the float assembly, open the dishwasher and remove the bottom rack. Remove the float cover (if any; it can be identified by the fact that the cover does not move up and down). The cover may snap in place or it may be fastened in place with a screw.

Lift and drop the float several times. It should move freely. If the float sticks, it may prevent the dishwasher from filling or draining properly. Remove the float and look for obstructions that may interfere with its free movement. The float usually snaps in place. If it does not come off with a small force, it may have to be disconnected from the float switch first.

You will need to Replace the float and float cover, If you found no obstructions and the problem persists, test the float switch.

TESTING PROCEDURE



To access the float switch remove the lower panel located beneath the door. The panel is usually held in place with two screws either above or below the panel. It may be necessary to first open the door to the dishwasher to reach the screws over the panel, then close the door to remove the panel.

Note the location of the float in the dishwasher's tub and you will find the float switch beneath it in the access area. The switch has two wires connected to it. Label the wires and connections so that you can properly reconnect them later. The wires are connected with slip on connectors. Firmly pull the connectors off of the terminals. You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If either is corroded they should be cleaned or replaced.

Use a multimeter to test for continuity. Set the multimeter to the ohms setting X1. Touch one probe to each terminal. You should get a reading of either zero or infinity. With the probes still in place, depress the button or lever on the switch and the reading should change to the opposite extreme.

If the switch fails either test, it should be replaced.


NOTE_ If the float, and float switch check out ok, and there are no issues here, the culprit will be a faulty water inlet valve. replace the valve in this case.

Hi, There is a float under the dishwasher to protect from flooding... If there is a leak and there is water under the dishwasher in the pan then the float switch will turn on the drain pump...
first I could remove the toe panel check in the pan for water... if no water still check the float it maybe stuck up (soap can get under the float and hold it up)
remove water and make sure float in down... if not you may need a new float switch...

in the front left bottom of the tub is a float switch; it sometimes is under a cover with a screw securing it it looks like a big round ball shaped piece of plastic and on the bottom of this float there's a pin going down a hole in the tub (the float pin sits on the switch and, water lifting up and down on the float moves the switch: listen for a distinct "click" as you move the float up and, down
you see; the float rises as the water fills the dishwasher tub closing the float switch and, signaling the washer to start cleaning the dishes
some times dirt prevents movement of the float but,waiting usually displaces the dirt/soap etc. just enough to make it work again until the float pin gets encrusted again the cure is to clean the float pin

There are three common causes for water leaking from a dishwasher door or float.

1. A problem with the wash system. Check the wash arms for cracks and or splits in the underside that can cause water to jet down and out the front of the unit. Check all water supply tubing in the unit as this can cause the same problem.

2. It is not uncommon for a water inlet valve to fail open and allow too much water into the tank causing a leak.

3. Over sudsing can cause a leak. Make sure fresh dishwasher detergent is used in moderation.
