Question about KitchenAid 24 in. KUDI01ILBS Stainless Steel Built-in Dishwasher
HI. I agree with your assessment. There may be some sort of blockage within the hose assembly. I recommend to inspect all hoses that correspond to the actual recirculation pump. Check the drain hoses as well.
The recirculation hose can be responsible for problems with poor rinsing of dishes and washing as well. Minor clogs will obstruct the water flow, thus, preventing for an optimal cycle. This issue will cause a low water pressure state, which in return, will hinder the rotation of the sprayer arms. To access the drain hose remove the lower panel located beneath the door. The panel is usually held in place with two screws either above or below the panel. It may be necessary to first open the door to the dishwasher to reach the screws over the panel, then close the door to remove the panel.The drain hose connects to the pump and runs to the sink drain (or to the air gap on top of the sink). The pump has a second hose that recirculates the water back into the dishwasher. The drain hose is roughly 1 1/2 inches in diameter. While inspecting the drain hose, check the recirculation hose as well for obstructions.
When checking for blockages, disconnect the drain hose from the pump, pinch the wire clamp with pliers and slide it up the hose. Place a shallow pan beneath the pump to catch any spillage. Remove the hose from the pump; wiggling the hose may help to loosen it. Check the hose and nipple to the pump for any debris. The only way to be certain the drain hose is completely clear is to disconnect it from the sink and run water through (such as spraying a garden hose through it at full strength). Disconnect the recirculation hose and check it the same way. Once you have cleared or verified that there are no obstruction within the affected areas, simply reconnect all the components and power up the unit for a test run.
During the test run, if you experience the same issues with low water pressure to the sprayers, move on to the water inlet assembly. The only other culprit, besides a clogged recirculation assembly, will be a failing inlet valve assembly. This assembly may be having difficulties with keeping the solenoid controlled valve fully open. This will restrict the normal water flow, thus, creating the issues you are experiencing as well. Use my quick testing procedure below to confirm proper function at the valve assembly.
To access the inlet valve remove the lower panel located beneath the door. The panel is usually held in place with two screws either above or below the panel. It may be necessary to first open the door to the dishwasher to reach the screws over the panel, then close the door to remove the panel. The water inlet valve can be identified by the water hoses connected to it. One hose will lead from the valve to the pump/motor assembly in the center of the dishwasher. Check that the hoses are securely connected to the valve and that there are no kinks in the hoses which could restrict water flow. There are two wires (four, if it has two solenoids) connected to the water inlet valve. Label the wires and connections so that you can properly reconnect them later. The wires are connected with slip on connectors. Firmly pull the connectors off of the terminals (do not pull on the wire itself). You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If either is corroded they should be cleaned or replaced. Use a multimeter to test for continuity. Set the multimeter to the ohms setting X1. Touch one probe to each terminal. A reading of infinity indicates a bad solenoid that must be replaced. Different brands and models will have various measurements, but the valve should show some resistance if it is functioning properly. If your valve has two solenoids, test the second one in the same way as the first.
