Frigidaire dishwasher noticeably louder - circulation motor?

Our Frigidaire dishwasher (Model GLD2450RDB0) has recently started making more noise and is quite a bit louder than normal. It still seems to wash & dry OK, but it sounds to me like the circulation motor, or possibly the drain pump, is going out. The noise seems to occur whether in upper rack or normal wash mode, and seems to pause with the cycle. Any easy, specific way to confirm the problem so that I can order parts?

Try to position the machine, so that you can run the cycle and watch the dish washer. Remove the back panel and hear the sound of origination. Take suitable action as per your convenience. You can clean & replace the bearings if they are worn or replace as a whole unit.

Circulation pump not running


Hi Dok, thank you for your post!

I'm not sure what you are referring to as the circulation pump; however your Frigidaire dishwasher, FPHD2491KF, does have a drain pump. Therefore, if your dishwasher is water left in sump, then more than likely it would need replacing. Is your dishwasher making a grinding noise? If so, then it would be advisable to connect with a professional to accurately diagnose the drain motor. You can locate a certified technician directly through the manufacturer website or in your local directory to determine what may be causing the issue at hand.

Best regards!

Check for obstructions inside in the bottom first and or the pump might be clogged. If it's not some type of obstruction or clog it is likely your motor has died or is almost dead. Start planning on replacing your dishwasher. I suggest to go with a higher end brand. Kitchenaid Superba EQ, Electrolux Wave-Touch, Bosch 800 Series for example.

Drain Pump

If the dishwasher is loud during operation, the drain pump might be defective or might have some debris in it. This is a common problem.

Circulation Pump

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the circulation pump sound, it's likely that the circulation pump motor bearings have failed. Once this happens the circulation pump will have to be replaced, the bearings are not repairable.

Drain Impeller

If the dishwasher is loud during operation, the drain impeller might be broken, or there might be debris in the pump. Generally, to gain access to the pump the top of the pump housing will have to be removed.

Pump and Motor Assembly

If the dishwasher is loud the motor bearings, drain impeller or wash impeller might have worn out. All three of these components are part of the pump and motor assembly. It may be possible to replace one of the impellers, but the motor bearings cannot be repaired. In that case the pump and motor assembly will need to be replaced.

Wash Impeller

The wash impeller is a small, plastic blade. The motor spins the impeller forcing water through the spray arms to clean the dishes. If one or more blades has broken off of the impeller the dishwasher is loud. The impeller can also scrape against the pump housing if it is damaged, warped or bent.

Circulation and Drain Pump Motor

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the motor sound, it's likely that the circulation and drain pump motor bearings have failed. Once this happens the motor will have to be replaced, the bearings are not repairable.

Water Inlet Valve

The water inlet valve is an electrically controlled water valve. When it is new, the water inlet valve is very quiet. Over time, the diaphragm inside the valve deteriorates and deforms. This deformation interacts with the water rushing in and can cause a loud vibration, buzzing, squealing or other noises. If the dishwasher is loud during the filling cycle, replacing the water inlet valve may solve the problem.

Frigidaire dishwasher model GLD2445RFCO is making noise


I have the same problem with my dishwasher. If you remove the kick plate while it is running, There is an electric motor underneath. If you push up and pull forward on the electric motor, the noise will stop. I used a block to prop it up and the noise stopped. You may want to try it.

All of a sudden, the dishwasher motor is making a loud noise. What might be causing this? Approximately 7-10 years old. Model # 665 15595792.


Hi.

First of all have you noticed whether the noise happens through the wash cycle or when it drains the water?
If its the former then it will be in your wash motor, the later in your drain pump.

Have you noticed whether a drinking glass was cracked or broken when you emptied your dishwasher?? if so it could have found its way into the wash motor or drain pump.

If the noise is high pitched ( like a saw mill) it is most liokely to be a wash motor bearing thats failed. If so you are looking at a new circulation (wash) motor.

Hope this helps

Diswasher motor making noise during wash cycle


It could be the impeller on the motor. The impeller fits over the shaft of the motor and might have split/broken up. That funny noise is probably the shaft spinning inside the damage impeller. Fortunately the impeler is fairly inexpensive and easy to replace. I believe there are one or two parts/covers to remove that are held in by a roughly half dozen torx screws.
