Dishwasher Repair- Replacing the Bi-Metal Fuse (Whirlpool Part # W10258275)

Hi it’s Steve from PartSelect. Today we
are going to show you how to change the Bi-Metal thermal cut-off on your dishwasher, and it’s
a really easy job. All you’re going to need is a #15-Torx Bit, a pair of wire strippers
and crimpers and a small flat blade screwdriver, let me show you how we do it. Now since we will be working near some electrical
circuits the first thing we need to do before we begin the repair, is to disconnect power
to the dishwasher, and if it has a corded plug on it, simply remove that from the receptacle,
and if it’s hardwired like most dishwashers will be, you will need to locate the fuse
or the circuit breaker and disconnect the power of that source. Next we will open the dishwasher door and
using our #15-Torx bit we will remove the top 6 screws around the console on some models,
on others we will need to remove all the screws so that we can access the controls inside.
Take note that the length of the screws may differ typically the four across the top or
a longer screw, make sure that we hold that door together until we get all the screws
removed, at this point we can tilt that up and separate the inner and outer door panels,
so that we can access the controls and now with the controls exposed, we look to find
the existing thermal cut-off and then we will have two large wires attached to it, one black
one and one black with a white stripe on it. The first thing we will do is we will cut
those wires about an inch back from the terminals and then we are going to remove that old thermal
cut-off. We will go to that first tape joint and we’re going to unravel that tape, and
we will remove those two wires, pull them through that, and we will re-tape that joint.
Now at this point we can pry that thermal cut-off out of its holder and it should just
pop right out, and then we can discard the old one. Next we will strip back of a ¼ of
an inch of wire in that existing harness, and we will twist those strands tightly
and then we will insert those into the terminal
block on the new thermal cut-off, and the wires are color coated and the intention is
to match them up, but it is not essential because they are not polarity sensitive. So first begin by making sure that the terminal
screws are loose enough to allow us to insert a new wire and make sure the wires are fully
inserted into the terminal block, and no loose strands and tighten the screws thoroughly,
it’s important that we have a good electrical connection here, and just make the wire a
little tight to make sure that it is secure, and the same with the second wire. Now we
have off of those secure, we’ll next mount the new thermal cut-off into the bracket,
snap it into place, make sure it is seated properly, and then we will take the harness
and connector, we will tuck those away from the components and using the two wire ties
that came with the kit we’ll secure those to that wire bundle. Do that about an inch back from the actual
connector, so snug those wire ties up putting the inch back from the actual terminal block,
and make sure that that’s tucked safely out of the way and close that control housing
off again, and make sure it fits slightly to the inner door panel, and then while supporting
it install a couple of screws just to hold everything together, and make sure all the
screws are secure and now we can reconnect the power and our repair is complete. I told you it was an easy job, thanks for
watching and good luck with your repair.

  1. Quick fix method. Don't cut the wires. Just a drop or two of WD40 on the plastic hook that holds the Thermal fuse in place. Slide it out to the side and it will unhook. Remove the two connectors. Tricky part, set the fuse on a paper plate, take a can of Keyboard duster spray, "canned air" turn the can upside down and spray the fuse for three of four seconds. It should be white with frost and is now well below freezing.
    Smack the fuse sliver side down on the counter top. Reinstall to test.

  2. I don't know how, but the Quick fix method reset the fuse! I you can explain how that worked I would be interested in learning.

  3. @ Ed Tourigny, That Quick Fix was like magic! Thanks so much for posting it. I replaced the fuse 2 years ago almost to date and couldn't believe it wasn't powering up again. I was just getting ready to order a new one and tried your method. Took 5 minutes and worked like a charm! Thanks Bud!

  4. I agree with @Kaimukiguy1, just remove the terminals and attach to new fuse, no wire cutting needed.

    However, I would use pliers to "crimp down" the wire-side terminals once removed so they "bite" firmly onto the new fuse terminals – ensuring good electrical contact. If they are loose, that would be a problem.

    This kit has you cut the wires and use a terminal block – to ensure good electrical contact, since this bi-metal fuse carries all the current for the dishwasher – several amps.

  5. If you don't have the "canned air" you also could put the fuse in a plastic bag (to keep out moisture) and freeze it for a few hours, then smack to reset. Use a meter to test for continuity (zero ohms).

  6. Theoretically, what's the worst that could happen if I bypass the fuse by twisting the wires together? I'm sick of this thing tripping.

  7. Great tutorial Videos, My Model #JDB3600AWP5 JENN-AIR dishwasher does not heat the water during wash cycle. The heat element gets hot during the Plate Warmer cycle so the heating element is fine. It was suggested i replace the Dishwasher thermostat Parts #: W10339474 which is placed under the wash tub. That did not fix the water heating problem. if the Bi-Metal Fuse is damaged what Dish-washing functions would no work? What are your recommendations?

  8. Hey there – this has happened for a 2nd time in 3-4 months. Bigger issue that needs to be diagnosed, or just crappy luck? If there a way to better insulate the fuse from heat to extend the life? A $15 part works for the short term, but if something's coming I'd rather be prepared. Thanks for the video!
