Questions & Answers

For Whirlpool Pump And Motor Assembly (Part Number: OEM18072192)

1 Answer

Don B, Check the power to the circulation motor at the time it should be running, using the tech sheet and a multimeter. Use the tech sheet to place the unit into diagnostics & check for error codes.

RLT 1964, You will want to test to see if the drain pump is getting 120 Vac to it. If there is not then the issue will be the control and if there is power to it then it would be the drain pump.

Hello Jessica, You should run the diagnostic cycle and pull the fault codes. To invoke the Diagnostics Cycle, perform the following while in standby: ¦ Press any 3 keys in the sequence 1-2-3-1-2-3-1-2-3 with no more than 1 second between keys. ¦ The Service Diagnostics Cycle will start when the door is closed. ¦ To rapid advance 1 interval at a time, press the Start/Resume key. Rapid advance may skip sensor checks as some checks require 2 complete intervals. NOTE: While in the Diagnostic Cycle, the Start/Resume feature is turned off (for example, Auto Resume after door interrupts) and the Start/Resume key becomes an individual advance key. ¦ Invoking Service Diagnostics clears all status and last ran information from memory and restores defaults. (Be sure to write down the fault codes as you go!) ¦ Drain and wash motors will pulsate on and off. ¦ Last ran cycles and options returned to default. ¦ Last ran delay returns to the lowest delay increment. ¦ Operating state returns to Standby upon completing or terminating the Service Diagnostics Cycle. Turn on all LEDs immediately upon receiving entry sequence (even if the door is open) for 5 seconds as a display test. Turn off all LEDs for 1 second prior to reporting customer error history. Thermistor (temperature sensor) checks: ¦ Turn Clean LED on if the thermistor is in its normal temperature range of 32°F to 167°F (0°C to 75°C). Cycle 2 and Hi-Temp LEDs flash in this interval. Press Cycle Select key in this interval to clear customer error history. Turn on Clean LED in this interval if dispenser current detected in the previous interval.

Jessica, Neither the pump or motor. It's most likely a failed "Start/Resume" key pad on the control panel W10475826 / W10475826 Console Assembly (Includes Active Overlay & Insert). Unfortunately the part is presently out of stock and would need to be ordered from the manufacturer. This will add a few days to the delivery process, once you place the order. Thanks,

Jorge, You will want to check to see if there is 120 vac getting to the drain pump and if there is not then this will be an issue with the main board.

Sam for Model Number whirlpool wdt920sadm

Dishwasher stopped working a few days back. Seems to fill fine (covers the heating element) heats fine, drains fine, but the water doesn't spray (arm doesn't seem to move at all). I have taken everything apart to check for blockage... nothing stuck. I have disassembled the circulating pump... no blockages there either, impeller turns fine. I applied voltage to the motor directly and it does seem to turn albeit not super fast. Probably could grab the impeller and stop it by hand. Since I have no clue how much these should flow nor do I have any previous experience with dishwashers i figured id ask what the issue may be. Also if motor needs to be replaced what is the latest part available? Seems they constantly replace motors with newer models.

Wayne, This unit has a thermal fuse located in the control panel. Check to make sure that the thermal fuse is not blown as it should have continuity when testing it. If there is no continuity then replace the thermal fuse. Check the pump to make sure that there is nothing that would be jammed in it that would cause the motor to not turn properly.

Thomas, To get into the pump you will need to remove the lower spray arm. There will then be some screw that are either a #15 or #20 torx head that you will need to remove. Make sure that once the cover is removed and you start taking stuff out of the pump that you take pictures so that you know how it goes back together.
