Bill, You will want to check the door strike to make sure that it is positioned properly as the door strike can stick if not positioned properly and make sure that the latch handle was installed properly.

Hello Sergio, This unit has no fuse. You should, however, verify both door switches are good before ordering the timer. One door switch has to pass 120Vac to the timer and the other passes neutral to the timer. If either one isn't closing properly, the unit can not operate.

Richard, If you take the latch assembly and push it onto the strike, like in a situation where the door is closed on both switches it should read closed. If the latch is not in position as the door being open then the switches would be open. If you get an open circuit when the latch is closed then the switches are bad.

Andre, It sounds like you may have a bad door latch assembly. The door should latch easily. Check to make sure that the strike is meeting up with the door latch properly. If not then it may be that the strike is not making good contact with the latch to activate switches.

Hello Dan, The child lock blinking indicates that more than 1 of the keypads is stuck. You can check your connection of the ribbon cable to the control board. If the connection looks good with no corrosion or bad connection then you will need to replace the keypad.

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

1 Answer

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.
