Question about Dishwashers

Dishwasher starts washing before float switch shuts off

Frigidaire gallery model CFDBV9G will not fill enough to prevent the wash pump from sucking air with the water. The float switch works perfectly, shutting off the water at the correct height BUT THE PUMP STARTS UP before the float switch turns off the water fill. I cleaned the screen in the shut-off. There is good flow through the fill hose. I was told at a repair shop that the cycle should not continue past the fill UNTIL THE FLOAT SWITCH SHUTS OFF. They said there must be a problem in the electronics which allows the cycle to bypass the fill switch shutoff.
Any advice would be welcome.

    What a waste of my time and yours !!!! 
    I was already told what the problem was. all you did is confirm it. This website is called FIxya not Confirm Ya. 
    What would be helpful is telling me if the timer is mechanical (ie can I turn a potentiometer or change out a small part)
    Or do I have to replace the whole PCB.
    Is it like an automotive PCB where a laptop has to be hooked up to re-program.

Frigidaire dishwasher shuts off mid cycle


Hello - From what you are describing it appears that the unit is attempting to run the cycle, but the wash motor is not coming on. Either the wash motor has failed or there isn't any or isn't enough power supplied to the wash motor. I personally recommend contacting a service provider to accurately diagnosis the dishwasher and to assist with the repairs.

Switch dishwasher on and starts up ok but when it comes to pumping water in it stops and does not do anything else.


Hello

Investigate these five areas if your dishwasher won't fill with water:

As water is filling your dishwasher, a float rises along with it. When the float reaches a predetermined 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. Check your float assembly. Replace it if you need to.

The water that fills your dishwasher lifts the float, and when it reaches a certain level, it acts as a trigger for the float switch. The float triggers the float switch to shut off, thereby shutting off the flow of water into the dishwasher. A defective switch may interfere with your dishwasher's filling ability.

Your dishwasher may not be filling with water simply because the water valve's filter screens are dirty and debris-filled. Gain access to your water inlet valve and try cleaning it out. This might be enough to solve the problem. You can learn how to access your water inlet valve in the replace a dishwasher water inlet valve section.

Alternatively, your water inlet valve could be defective altogether. That could be the reason your dishwasher is not filling. Test it for continuity. If it is not functioning as it should, replace it.

Your dishwasher's drain valve is regulated by a drain solenoid. If the solenoid is malfunctioning, it may not allow the drain valve to funtion properly, which in turn could be the reason your dishwasher is not filling with water. Investigate your drain valve and test the solenoid. If the solenoid is faulty, replace it.

I have a frigidaire 3 speed profesional series dishwasher that will not get my dishes clean. It is only 4 yrs old and i am getting very frustrated. Any suggestions before i pull out my hair? i am having...


Hi

As the water inlet valve is fine and it fills with water then the issue seems to be with the float switch assembly that is bad and should be replaced. Float assembly is found inside the dishwasher's tub, on the bottom. The water that fills the dishwasher lifts the float, and when it reaches a certain level, it acts as a trigger for the float switch. The float triggers the float switch to shut off, thereby shutting off the flow of water into the dishwasher. A defective switch may interfere with dishwasher's filling and/or draining ability. Use voltmeter to test the switch. Set the device to the ohms setting x 1. Take each probe and touch them to one switch terminal each. This should produce a reading of either zero or infinity. Continue to touch the probes to the terminals, and press down on the switch's button. The reading should change to the opposite extreme. If the switch fails either of these tests, you should replace it. Hope this helps...please post back for further assistance.

No water is coming in the dishwasher. I can hear the water running, but the water is not coming into the dishwasher


If you can hear the water running - but it's not filling, you most likely have a drain problem, which is being stuck open. Usually the motor kicks in and either pumps the water through the wash arms (during wash cycle) or through the drain (during drain cycle) the switch that/or flap could be stuck on the drain and it is pumping it out the drain all the time instead of the wash arms.

Water will not fill the washer


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.

Model: Frigidaire GPDB998JC0 It fills and drains


Check your water level to see if the water valve is even filling up properly. After starting the cycle, listen when the water fillup begins and ends. Open door and see if there is enough water at the bottom. Should fill up to the float valve. If there is not enough water, the valve needs to be replaced. Costs about $25 and can be replaced diy if you are handy with pushing back the hose clamp and undoing and redoing the water line connection.
Make sure you unplug the electric, and shut off the water before you even want to look behind the toe plate. Dishwashers have high electric hazard behind the toe plate..

Dishwasher will not run after filled with water


The float switch in the tank is bad,also if water only trickles in your fill valve is going bad which will not let it fill all the way to start wash cycle. Fill tub with pot of water to raise float, if wash cycle starts,replace fill valve,if not,replace float switch.
