my dishwasher makes a sound like there is something in the bottom when it is draining. like being hit with a fan bouncing around. I can not see how to get down into the area where the pump is to see what is in there. Not sure how something could have gotten down in this area.
Answer Becky, Your dishwasher has a separate drain pump WD26X10025, You can't access it from inside the tub. Yes, it is possible to get a small article indide the drain pump and it will make noise, similar to your description. Here's some help, from the service manual " To remove the drain pump: 1. Disconnect power. 2. Remove the dishwasher from its installation. 3. Lay the dishwasher on its back. 4. Disconnect the 2 wires from the drain pump. 5. Loosen the 5/16-in. hex-head screw, then pull the drain pump off the sump." In most cases, you don't have to remove the dishwasher from the cabinet, but it makes for an awkward, "tight" area to work in.
Like another of your above questions, My dishwasher is working fine, but makes a loud rumbling sound when running. Repair guy said he would replace motor/pump assembly. It didn't exactly look like brain surgery, but I wanted is it a tough fix? Also does the assembly comes with instalation instructions?
Answer Hello Jim,
This is not brain surgury but it is a big enough job that if you have never done it before, I recommend that you pull the unit from its' installation and lay the unit on its' back to perform the repair. It is just too easy to cause a water leak with the unit in place. The new pump and motor assembly will not come with instructions.
My dishwasher has recently started making a loud "rumbling" sound, whenever the wash pump is running. It almost sounds like the pump is cavitating. The unit seems to work fine, but the noise is very irritating. The sound is definitely coming from the underside of the dishwasher. I checked the filter screens (all clear) and replaced the spray arms. No change in the sound. Before I disassemble this thing, do you have any ideas on what could cause this? Thanks...
Answer Brad, There are a couple of other things to check. Remove the sump cover WD22X10077 and remove the filter and check the lower portion of the sump for small articles such as chards of glass, seeds, etc. Check and make sure you have the proper fill level in the bottom of the tub " During a normal wash cycle, the water level in the tub will cover the sump screen or be just to the rear edge of the heater bracket. The dishwasher will fill with approximately 1.2 gal. of water. " If there's not enough water in tub/pump, the motor will make a noise. Then Make sure the detergent or rinse agent is not "foaming", this will also make the cavitation noise and increase the noise level. Thanks
I know I need to replace the motor (above part) (the blades keep getting stuck and I have to use a screw driver to rotate it manually before the wash cycle goes on). Can I use the existing Impeller / Seal by taking it off the malfunctioning motor and putting it on the new motor? Does the part above include the impeller preassembled already?
Answer Hi Ray. You can try to use the original parts as mentioned.... But consider this, the impeller is at the same motor shaft end and has taken the rpm speed and "abuse" of the issues. Inspect them carefully. The seal has to work as new. For a few bucks more you can have a new tight set up and the satisfaction of not worrying @ a seal lock up or leak(unknown to find). Impeller seal kit part # WD19X10038. Motor assy. part # WD26X10045. Thank You.
