I have a fridgidaire gallery dishwasher. It doesn't shut off at the end of the cycle, pump sounds like it's running and the bottom spray arm doesn't spin when in a cleaning mode. It spins freely when the machine is shut off. Please advise.

Remove the bottom rack and check the pump area to see if there is a lot of debris in it. When the pump clogs, the spray bar wont spray and soap just sits at the bottom. The spray bars could also be plugged.

Many Frigidaire dishwashers come with the promise of being the "quietest dishwasher in its class," according to Frigidaire. However, a quiet dishwasher doesn't necessarily mean that the dishwasher is silent, as some noises are normal. It can take some troubleshooting at times to determine if a noise coming from the dishwasher is typical or if it indicates a larger problem Listen for the sound of water filling and draining throughout the wash cycle. These sounds are normal and do not indicate an issue.

2 Pay attention to the drain motor, which operates at the beginning of each cycle. This noise should be fairly quiet and should not sound like a loud, grinding or banging sound.

3 Note that the sound will change when the wash cycle moves between the lower and middle spray arms. This sound should be temporary and fairly quiet.

4 Look for hard items in the dishwasher grinder or filter if a loud crunching, buzzing or grinding sound is heard. The dishwasher can typically grind up these items within one or two cycles, but the item may be lifted out and discarded to eliminate the sound.

5 Remove the bottom rack and spray arms from the bottom of the dishwasher if there is a loud noise coming from the dishwasher that does not resolve itself. Look inside for the impeller, which is round and spins. Remove any debris that may be clogging up the impeller or pump.

There is only one motor -- it runs a water pump for recirculating the water when it's washing and runs a water pump when it's draining.

It sounds like the spray arm is making the noise -- this is the part thru which the motor / pump forces the water during the wash cycle -- the pumped water causes the arm to rotate -- a warn or loose spray arm or mount is likely the problem.

Or, it could be just some utensil stuck in the bottom of the dishwasher which the spray arm is rubbing.

More info, let me know.

Remove the lower spray arm and take off the pump housing and upper pump section. Inspect the pump impeller for damage. I expect you will find some garbage stuck in there, perhaps clogging the pump outlets. (Also, look inside the spray arm and remove any debris.)

Next, remove the trim panel at the bottom front of the dishwasher, get out your work light, and inspect the motor housing for evidence of a leaky pump seal (e. g., dried soap from drip tracks). A damaged or worn impeller or a leaky seal indicates the need to install a pump rebuild kit (dishwasher pump parts are not often sold separately because it is presumed that these are all routine maintenance wear parts).

Is water also standing in the bottom like it isn't getting pumped out? If so, probably the drain system is plugged and everything below the lower spray arm needs to disassembled to the deck--noting the position of each piece as they are removed. Look for food plugging holes in the deck and any obviously damaged parts. Clean the large screen in vinegar and hot water--let soak for a while to remove water and food deposits. Check the drain hose from end to end looking for kinks or other restrictions. Make sure the pump mechanism at the bottom turns freely. Check both spray arms for plugged spray holes or split seams. Reassemble in reverse order. Run a cycle without dishes to clean further--make sure the water drains out at the end. Listen for proper water movement while running. Open the door to inspect progress several times.

If its just that corner check that it is level (if not leak could be somewhere else)

Then check your hoses and valves for holes or leaks (try putting some food dye water when running to see easier

Most likely a loose hose connector or hole in the rubber hose

Dishwasher Basics The main parts of a dishwasher are: Control mechanism
The control mechanism is located inside the door behind the control panel. Many units use a simple electro-mechanical system: a timer determines how long each part of the cycle lasts and activates the proper function at the proper time (such as the detergent dispenser, wash spray and draining functions). Units that are more expensive might have a computerized control system. Modern units also have a door latch that must be closed for the unit to run. Some also have child safety locks. Intake valve
This is where water from the home's water supply enters the dishwasher. The unit's pump doesn't pump the water into the basin – when the intake valve opens, water pressure drives the water into the unit. Pump
An electric motor powers the pump. During the pump cycle, the pump forces water up into the spray arms. During the drain cycle, the pump directs the water into the drain hose. The motor-pump assembly is mounted beneath the basin, in the center of the dishwasher. There are two main types of pump:

• Reversible
  These pumps switch between pumping water to the spray arms and pumping water to the drain by reversing the direction of the motor. Reversible pumps are usually vertically mounted.
  -->Reversible pump
  
  
• Direct-drive
  The motor runs in one direction, so the direction of flow is switched from spray arms to drain by a solenoid that opens and closes the appropriate valves or switches one hose connection to another. Non-reversible pumps are usually horizontally mounted.
  -->Direct-drive pump
  
  

Dishwashers can be installed in either a portable or a permanent configuration. Portable units have finished sides and top that can be used as a countertop. When not in use, the machine sits in place next to the wall. When it's time to run a cycle, the unit can be rolled on casters over to the sink, where it connects to the faucet and plugs into a nearby outlet. In a permanent installation, the dishwasher goes underneath the existing countertop and bolts into place. Hoses underneath the kitchen sink connect directly to the hot water line and the drain line, and the unit usually plugs in under the sink as well. Both types of installation require a 120-volt grounded line.

possible you have a leak and the bottom tray has water in it. tilt the machine back to 45deg and see if water runs out of the back. if it does, after putting upright, the machine will work - then find the leak!!

check the drain pump for foreign object in the pump if nothing is found replace the pump

If the washer is not used regularly the shaft can stick to the seals and prevent the motor from spinning. This happens quite regularly for me if I don't use the washer often. You can just take off the bottom panel - after shutting off power to the dishwasher - and access the motor. you should see some fins and then just try to spin the motor by hand. It usually takes about 90 degrees of rotation before the motor breaks free from the seal. You'll have to fight through the spring-like resistance created by the seal-shaft adhesion. After it breaks free the motor spins freely and you should be all set to go. I haven't found a more permanent fix for this other than running the dishwasher more regularly.

1.does motor run? no. replace motor. 2.open door and leave the bottom rack inside dw.spin the spray arm underneath the bottom rack by hand. it should spin freely without binding. if it doesnt spin freely take out the bottom rack and try again. if it does spin freely then your bottom rack is laying on your sprayarm preventing it from rotating. 3.you could also not be getting enough water into your dw.
