I am not aware of any float switch in this model. If this a portable dishwasher and assuming the water inlet connection is open, it is likely the water inlet solenoid could be faulty. Check this site for location of parts.

SOURCE: Frigidaire dishwasher model FDB857RJS1 not pumping

HI, under the sump housing, there is a major issue concerning the circulation motor. there is a wash impeller that is connected to the circulation motor, via drive shaft and stud. this assembly has been stripped, due to a possible jam that was caused by a foreign object. the impeller is basically, producing the grinding sound you are hearing, you will need to replace this damaged wash impeller asap. it will ruin the motor soon if it is not removed.

This wash impeller is responsible for the flow of water during the wash cycle. it is not completely off the shaft but, eventually , it will break off soon, causing major damage to the circulation motor.

SOURCE: Dishwasher always fills to float valve

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
Pump
Drain valve and/or solenoid
Belt
Motor
Timer
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.

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.

What is the float switch


I have no real experience with float switches on dishwashers, but have with some in humidifiers. It's a piece of styrofoam on a narrow metal stick that lifts when the appliance fills with water & lowers when the water empties. If this gets stuck on something, like a dishwasher rack, the unit won't fill or empty the water & the cycles won't work properly. Take a look & see if there is such a thing hung up somewhere in the dishwasher. If you can loosen it, your dishwasher should work again.

No water entering dishwasher; motor running


The water-inlet valve lets water enter the machine. First Check to see if the valve is getting water. Make sure it’s not clogged. There is a screen on the inside of the valve, this sometimes gets clogged up with debris. Check to see if you get power to valve when unit is put into operation may take a couple minutes to start a fill. If you have power and it’s not clogged up replace the valve .If you have no power to the water inlet valve check float switch. This can be done by checking the continuity. There is a video of this at http://appliancehelponline.com/dishfloatwaterinletvideo.html this will walk you checking the water inlet valve and the float switch. It may be a different model but the testing procedure will be the same. You can also enter your model # for diagrams and illustrations for most models. All parts come with installation instructions.

Dishwasher - no water coming into it


If there is no water coming in the machine check first the water supply has not a tap and this is closing.
If water is supplied regularly, then the problem is either with the inlet valve or the float switch.
See the following indications from repairclinic:

" 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."
