Dishwasher Wired to Switch.....Have You Ever Seen This?

By
Home Inspector with Fort Worth Home Inspectors - Green Tag Inspections

 

I ran across this again today and am wondering:

1. Why they are wired this way.

2. Do they do this in other parts of the country.

3. How many of you have seen this also.

The first time I saw this was about 7 years ago when I was inspecting a fairly new home and noticed the dishwasher was not powering on. I checked the breakers in the panel and none were tripped so I just assumed that the washer was not wired or broke. I then turned on the garbage disposer but at first flipped on the wrong switch above the counter and noticed the dishwasher came on. I could not understand why the dishwasher was wired through a wall switch, so I just assumed the electrician messed up on the wiring. But over the years, I have run across this a few more times and again today. Do any of you understand why they do this? I guess if you answer the phone in the kitchen and want to pause it, you could flip the switch, but it would be no more trouble to just crack the door open. On these newer electronic models, I'm wondering if this would cause it to lose the cycle program and reset.

Any thoughts?

Hey Kent,

I use to have a house w/o a dishwasher, so I installed one. In the course of wiring it up, I didn't realize that I wired it into a switch in the basement. It took me a few days to figure out why it was only working speradically..... When I realized what I did, I couldn't believe it.

I have yet to find a home with a switched dishwasher, but as a child-proofing safety measure it does make a lot of sense.

Using a switch for the disconnect means is OK unless you have a shared neutral. Then a cord and plug is required.

This all depends on what was codified in your area at the time of installation.

Its for code.  Some areas require a serive switch installed

In Austin area, it's common to have the on/off wall switch.  I've had several buyers call me after the sale wondering why the dishwasher all of a sudden wasn't working not realizing there is a on/off switch.

I have never heard of that before. Thanks for the info. Now if I ever run across a dishwasher that has no power, I'll be on the lookout for a wall switch.

Nick,

It sounds like you are connecting the hot (black wire) and the neutral (white wire) to the switch, causing a short and blowing the breaker. The switch should just break the hot (black) wire so connect each side from the dishwasher and the electrical feed wire of the black wire to the two switch terminals, then white wire from the disheasher to the white wire from the electrical feed. Then connect the bare ground wires together.

Hope his helps,

Kent

With all the recalls on new dishwashers, because they can catch on fire, its a great idea to have a switch and turn it off when you're not using the dishwasher.  Sounds like someone was thinking ahead :-)

Here's a good reason: I am instaling a switch for the dishwasher in my mom's house. Why? It's a KitchenAid with soft touch controls on the front (not the top). Every time my mom reaches up for stuff in the cabinet above, she bumps into the switches on the dishwasher and turns it on. There IS a lockout switch on the dishwasher - but that's difficult to engage and clear.

Maybe the people who have the dishwasher wired this way have similar issues : - )

I know this is an old thread but I think it's an important one. Several days ago 11/15/2015 while at home my wife started the dishwasher a Kenmore Elite series purchased in 2005. As we walked away we both heard a strange sound (sizzling) as I turned toward the dishwasher, that just started it's cycle I saw what I thought was steam but in fact smoke followed by spark than fire coming out of the circuit. I was close so I opened the dishwasher to stop the cycle but it kept running and the water shooting out. Water + Electric = bad situation. I immediately shut off water under sink than ran to electric box to turn off breaker (great idea to have them labeled) As I though about the situation, a "kill switch" above the dishwasher would have been very handy. This is why when installing new dishwasher I am putting one in. As A side note I will NEVER purchase another Sears/Kenmore product ever again, not because this "accident" happened and would have burnt my house down if we just started and left the house, but because of the response from Sears "customer support" to my inquiries. There only response was that it is no longer in warranty so the only thing they can do is send over a service person at x.xx per hour to take a look. I told them I was not interested in warranty, just interested that this does not happen to someone else, but they didn't seem to care. After some looking around on the internet now I know why. you can check for yourself http://kitchenaidfire.com

Peter, thanks for your input.  I agree that a switch at the location, or that it be required to plug-in under the adjacent sink cabinet would be a good idea.  However because you situation is so rare it is not likely to become a code issue until someone dies.  It is a really good idea to make sure homeowners are aware of where to turn things off in a hurry and to make sure that everything is properly labeled.

I like it wired this way so when my toddler turns the dial for fun she doesn't turn on the dishwasher because we keep the switch off until we run it at night.

This is an old thread, but I've seen this all over the place. The dishwasher is an "energy vampire" like a TV. It's on a switch to reduce electricity usage/bills because unplugging it is not practical (unlike a TV).

Bought a manufactured home in Franklin County VA. 2nd trip down dishwasher was "broke" (Old model with mechanical control system) Started taking it apart, but no apparent failures. Checked under the counter for wiring problems (vermin attack?) -- Found the wall switch above the dishwasher and it worked. Was going to change it to hardwired, BUT - after this thread, I will stock a 20 amp switch and get a dymo label maker to make sure the next guy doesn't gut the house looking for the problem. Grandma used to "break" her tv evert week, She unplugged the TV to Vacuum and forgot to plug back in!
