Frigidaire 24' doesnot clean the dishes after complete wash cycle. sometimes it seems as if the top rack does'nt even get wet please advise

Then use the other rack....or wash dishes in the sink.

Good Afternoon Stephanie,

I understand the spray arm is not raising all the way in your Frigidaire dishwasher, model# FDB750RCC. I also see that the dishes on the top rack are not getting clean due to this. The spray arms are stationary where they are attached to, other than turning due to water pressure. Please try the following solutions:

• Choose another cycle for longer washing time.
• Check rack loading section for proper loading-avoid nesting items.
• Home water pressure may be too low- should be 20 to 120 pounds per square inch (psi).
• Check incoming water temperature. It should be at least 120 degrees F.
• Select HI-TEMP WASH option.
• Check water hardness. For extremely hard water, it may be necessary to install a water softener.
• Use fresh detergent.
• Check to make sure funnel in top rack is not blocked.
• Make sure items are not blocking the spray arms, preventing them from rotating.


I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your appliances status has changed successfully. Hope this is helpful.

-Best Regards-

It is likely that sufficient water is not coming from the top arm. These dishwashers oscillate the water flow between top and bottoms sprays alternatively. This ensures water is pumped with adequate force. It is possible this mechanism is not working correctly. The device called check ball item 58 in this diagram actually does this function. The ball might be out of shape or not sitting properly causing incorrect wash water movement.

Possible that the motor impeller has good particles in it, causing poor water pressure, which would be most evident on the top rack. You would have to remove the spray arm, then the filter, then the torx screws to get at impeller....unfortunately, that model of dishwasher isn't the greatest in the first place for washing, since it only has the one spray arm.

I expect your filter is clogged which does not allow sufficient water to get from the pump to your spray arms. Thus they do not clean out the detergent nor do they clean the dishes. You might test this by placing a glass right side up in the top rack and run a normal wash cycle. The glass should fill at least half way with water.

Factory Defect, where I was given full refund plus re-installation costs from Lowes...

HI,

The top rack is not cleaning because of low water pressure from the wash motor to the upper spray arm.
Assuming the top spray arms are clear of debris, remove the lower spray arm to access the wash motor. Remove the 4 torx screws and the filter (accumulator assembly). Remove the torx screw and the inlet protector that covers the chopper assembly. Make sure the chopper is not broken (broken chopper will fill with debris and block water flow). While holding the chopper blade, reach inside the "D" shaped opening on top of the motor and spin the wheel/motor by hand in each direction to make sure either the chopper gear or the motor gear that drives the chopper is not broken. Replace the chopper if necessary . If the motor gear is broken, replace the sump and motor assembly . Remove any debris from the sump area in the process.
You don't have to shut the power off to the dishwasher because the door will be open, but if you feel more comfortable, do so.

thanks,

Clean ot replace circulation pump.

An aging water-inlet valve can sometimes fail slowly, rather than all at once. It can shudder on and off rapidly, causing the incoming water lines to shake, rumble, and rattle--sometimes violently. If yours is doing this, replace the inlet valve.or may be its due to
Heater fanIf the heater fan bearings are rusted or worn, they may squeal, or scrape loudly during the drying cycle. If this is the problem, replace the fan motor. Alternatively, the fan blade may be loose. If so, you need to replace it.

If the unit is cleaning the bottom dishes normally, try unplugging the unit for 5 minutes to reset the control board.  If that doesn't work, then the control board needs to be replaced.  The problem is that control board is not diverting the water to the upper wash arm during the cycle.  Possibly a program problem
