The motor is making a whirring noise after starting.


If your Swimming Pool or Spa Pump Motor is humming and/or has very little or no water flow, please follow the following directions.

1) Remove the pump motor from the system. 2) Disassemble the front half of the Pump Pot Housing from the back half.
3) Check for any foreign obstructions which would jam the Impeller and remove it
4) Next, inspect the Pump Motor Impeller itself. (This is a high suspect part). See if there is any sign of wear or breakage. (This happens over time from debris in the water passing over the impeller). If so, your Impeller is damaged and requires replacement.
5) Next, remove the cover from the rear of the Pump Motor. Using a large standard blade, (straight), screwdriver or wrench... turn the main motor shaft. Listen for grinding and/or rumbling and feel for any restrictions while turning. If you hear or feel either, your bearings and/or brushes are damaged and need replacement.
If everything seems to be in good working order, then you need a new pump... not just replacement parts.

If everything seems to be in good working order, then you need a new start capacitor or your motor windings are fried and you need a new pump.

We have taken apart the bottom of the dishwasher to be sure no food was clogging the exit. It is clear but the water still willnot drain


HI In most dishwashers, the water pump is located under the lower sprayer arm. This component pumps the water through the dishwasher. The pump has two impellers, top and bottom. These, as well as other components, can become clogged with food or detergent. Here's how to disassemble the pump:

Step 1: Remove the cap that holds the sprayer arm on.

Step 2: Remove the sprayer arm, the screen, the pump housing, a bolt, the upper impeller, the food disposer blade, a spacer plate, the impeller hood, a flat plate, an O-ring, and the lower impeller. Lay the parts out in order as you disassemble them so that you'll be able to reassemble them properly.

Step 3: Clean the parts thoroughly with a mild detergent solution. If any parts are worn, replace them with new ones made for the dishwasher.

Step 4: Replace any seals, such as the O-ring or other washers, with new ones.

Step 5: Reassemble the pump, keeping the parts in order.

To reach the water pump, remove the sprayer arm and screen and then the pump housing. Remove the bolt, and the pump components can be disassembled.

On some dishwashers, the lower impeller serves as a drain pump. This type of system usually has a reversible motor; machines with nonreversible motors have drain valves, as detailed previously. If your machine possesses this impeller pump system, and the water will not drain from the dishwasher, clean the lower pump impeller. This may solve the problem. Otherwise, call a professional service person.

Mine is a FDB635RFS4 model - issue is loud screeching noise


i recently had the same problem of a loud screeching noise. my unit was installed new in 1999 and has worked well up to this point.

when i disassembled the tub water filter i found the filter was heavily clogged (it is supposed to be self cleaning), and i also found glass shards from a broken wine glass. i further disassembled the plastic housing under the filter ( held in place by three torx drive screws ) which covers the pump impeller and holds the lower spray arm. while i did not find any blockage in the pump area, and no abnormal sound when i turned the impeller by hand, i did find that one of the pump impeller vanes has a small chip which probably makes the impeller unbalanced resulting in more than normal vibration. i cleaned the water filter and reassembled the parts and the original screeching noise is now gone.

Check and make sure that there is nothing blocking the pump inlet underneath the mesh removable filter. It should be making a whirring sound like it's trying to pull water in in a cycle. If it's not making that noise your pump is shot.
