What it is: As mentioned before, a dishwasher has plenty of electrical wires inside that connect each of its components together. That way, you’ll have a photo reference to guide you in reinstalling the new wire harness. To do this properly, you’ll want to make sure that you have the user manual or tech sheets to guide you through the process.īesides that, it would also help take photos of the older wire harness before removing it. The tricky part about replacing the wire harness is connecting everything back correctly. Why it fails: Some manufacturers recommend changing the wire harness if you’ve changed the thermal fuse more than once. So, rather than trying to inspect and fix individual wires, wire harnesses make it much more convenient to replace the entire set of wires altogether. Think of it as a complete set of wires prepared at ideal lengths to fit your dishwasher perfectly. To put it simply, a wire harness is a bundle of wires that are used inside the dishwasher. What it is: When replacing the thermal fuse, some manufacturers will also recommend changing the wire harness as well. Once you’ve found the broken wire, all you have to do is cut and splice the wire together using a wire nut.Īs a precaution, it would be wise to look out for any additional broken wires at the same time. That will require a careful and up-close inspection of every bit of wire throughout the machine. The difficult part is locating the broken wire in the first place. How to fix: First and foremost, always disconnect the dishwasher from the power supply and drain the water from the appliance.įixing a broken wire is very straightforward. That can lead to a short circuit, which causes the thermal fuse to heat up to the point that it cuts the circuit to protect the rest of the machine. The wire could be of low quality, or perhaps a part of the wire suffered some kind of impact that was strong enough to break it.Ī broken wire may come into contact with other exposed wiring or the metallic parts of the dishwasher. Why it fails: Despite being insulated or coated, wires can sometimes break for several different reasons. Those documents usually have diagrams that help you locate and identify the wires in your dishwasher. To be sure, please refer to the user manual or technical sheet that comes with the machine. Usually, they’ll be behind the panels at the bottom or the rear of the dishwasher. The exact placement of those wires may differ slightly depending on the way your particular model was designed. Then the drain motor will NOT respond and will remain off.Typically, these wires are kept out of sight behind panels that must be removed before you can access and inspect them. ➔If the control is not OK (still sees shorts with the keypad unplugged), It will respond by turning on a Drain Motor for 2 minutes.Ĭheck and/or replace the keypad if the control responds OK. ➔If the control is OK (no longer sees shorts with the keypad unplugged), Make sure all other connections are made.Ĥ. Open console and disconnect the keypad ribbon connection from the control (at P1). To determine if the control or keypad is faulty, do the following test:ġ. Indicates one or more key switch lines are stuck or shorted on either the control or the keypad. Therein it is written this simple procedure for determining whether the touchpanel or control board is the culprit:Ī rapidly blinking LED over one of the keys of the keypad (or sometimes a “dead” keypad/console) Remove the kickpanels below the door and you'll find a tech sheet in a plastic pouch (unless some sleaze bag stole it). The conundrum you face is which part to replace: the touchpanel or the control board?Įxperience says that it's almost always the touchpanel that goes bad in these cases- a keypad gets stuck closed or worn on the inside so it no longer makes contact.įortunately, there's a way to tell for sure without any guesswork! none of the lights on the panel work and the dishwasher won't runĬould take on lots of other variations but the thing they'll all have in common is that dishwasher won't run. Normal light keeps blinking but the dishwasher won't run Many times when troubleshooting a Whirlpool-built dishwasher (also sold under the Kenmore and Kitchenaid brands), you'll have a problem that looks like it could be either a bad touchpanel or the control board, but you can't really be sure.
