Questions & Answers

For Whirlpool Door Switch Kit (Part Number: OEM9310752)

Trey for Model Number Whirlpool Dishwasher DU840SWLQ0

2 Questions: First- I can't find this model# on the Whirlpool site, Google or your site as a correct model #. Second- The washing machine is running a full cycle but the door is not opening to release the soap. I pulled the door handle switches and there is a little discoloring on the metal connectors but nothing extreme. Do you think it's the switches or the timer? I have the part number for the switches but what is the part number for the timer if that's what you think it is? Thanks

Trey, Since your dishwasher detergent and rinse dispenser are a "mechanical" operation, you'll need to dismantle the door assembly and control panel and check the timer, timer cam and cam follower. We'll send you some "basic" information for your model number that you supplied,it should be helpful.

Steve, You're just a little off target, a faulty door switch would distrupt power to the control and you'd have no lights and the unit would do nothing at all. You most likely have a fault in the control panel/key pad assembly 8051721 " If the control detects that a key is stuck in the depressed position, dishwasher operation will be suspended and the control will flash the light for that key until the condition is corrected. If a key without a light is stuck or multiple keys are stuck, the control will flash" You will also need to reset the control "HI TEMP WASH, AIR DRY, HI TEMP WASH, AIR DRY or POWER SCOUR, AIR DRY, POWER SCOUR, AIR DRY If the sequence is entered after starting a cycle, the Rapid Advance feature is turned on, which allows the operator to manually advance the currently running cycle, interval by interval, by pressing the Pots & Pans/Antibacteria or Heavy/Soak & Scrub key." and allow the diagnostic cycle to run the complete test mode. Thanks and Good Luck

Hello, you will want to look at both door switches 4318273. You will need a Multi Meter: TJMA-DMT3 to test the switch, it should read closed when you press it in and open when you release it. If both switches are reading good you might have a defective timer. Unfortunately the timer is no longer available, sorry.
