Question about Frigidaire 24 in. FDB126RB Built-in Dishwasher
The dishwasher fills only to cover the "screen" in the bottom and does not reach the overfill valve. What can we do?
SOURCE: Indesit dishwasher overfilling
There are two ways that dishwashers generally fill. One is a float inside the tub, the second is a tube which fills with water, loops and goes to a pressure switch below the machine. That switch is usually about 1.5 inches in diameter, two wires and a small hose going to it. The float witch is found below the float in the motor area. With the float, sometimes they jam with too much old detergent or food goo. Clean out. Both can have the switch weld closed. Change the switch in either case. Since the unit is not filling with the power off, I'm going to guess the water solenoid is okay.

Couple of things that come to mind here... May be helpful or not - but after all this is free ifo and probably worth what you are paying!!!
1: Have you tried removing power from the appliance?? All these modern appliances use a microprocessor and - like MS WINDOWS - need a kick up the bum now and then - (Well.. with Windows it seems to be every day- hour -minute - or so)
2: Dishwashers are installed with water reduction valves, so there could be a problem with one of there (particularly the hot water side).
3: The water inlet is controlled by soleniod valves (read: electronic valves). If the valves are not opening, no water will enter the appliance, so there could be a problem with the valves.

An Idea: the Overflow sensor or float is bad, stuck, disconnected and its messages to STOP filling aren't getting thru to the CPU
This is usually located in the right frony of the machine or in the side wall. Float types get gummed up with 1/2 dissolved soap powder (god what we do tho the water systems) see if it moves. Sensor types have a hole that feels or senses water. If clogged, they lie. Clean out with toothpick and blast with a bit of hot water and air. Retry
If fixed, let me know... if not, see the yellow pages for parts dealers ;-)

There are actually several possible causes of your problem. I will briefly describe each in hopes that you can isolate the problem and will then know how to proceed.
If the water doesn't drain from your dishwasher, check these:
Drain line/air gap
Drain valve and/or solenoid
Drain line/air gap A clog in the drain line or air gap (if there is one) is the usual reason that a dishwasher won't drain. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. If you remove this line, you can clear any debris from the hose or hose connection. Be sure to reattach the hose before starting the dishwasher again.
Pump Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support.
Look for an impeller--a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.
Drain valve and/or solenoid Many dishwashers use a drain valve with an electric solenoid. When electricity flows to the solenoid, the valve opens and diverts the water to the drain. Sometimes the solenoid, or the diverting lever, sticks and prevents the dishwasher from draining or filling properly. Try to free up the solenoid to lubricate the lever. Otherwise, you may have to replace the solenoid or pump assembly. With these systems, the motor always rotates in one direction. When it's energized, the drain valve diverts the water.
Other dishwashers simply reverse the direction of the motor to drain the dishwasher. These units don't have a drain valve. Instead, there's a drain hose connected directly to the pump housing.
Belt One brand of dishwasher uses a belt to drive the pump. If this belt is broken or has fallen off, replace it.
Motor If the motor isn't turning or working, the unit won't drain. First check to be sure you have power to the dishwasher. If not, see the section "It doesn't work at all." If the motor hums but doesn't turn, it may need to be replaced.
Some dishwashers are susceptible to getting stuck if you don't run them regularly. If you haven't run the dishwasher for more than a week, you may need to manually spin the motor to free it up. If the motor is defective, you need to replace it. Dishwasher motors can't be serviced.
Timer Part of what the timer does is control the motor and drain valve. If the timer doesn't work properly, the water may not drain and you need to replace the timer. This problem is uncommon.

using FixYa. If the dishwasher is overfilling it's caused
because of water-inlet valve going bad. This valve is usually at the bottom
left or right of the dishwasher, behind the lower access panel. It's the device
with the main water line from the house, a rubber tube to the dishwasher, and
two wires attached to it. If the water-inlet valve is defective, you need to
completely replace it. Please rate the solution if the issue is resolved or post a comment
for further assistance.
