| Some US washers don't but many do. However, US washers tend to not heat water as quickly or to as high of a temp. The video cites two reasons: 1. US power being 110V vs 220v. 2. US dishwasher heating elements being limited to 800 or 1000 watts because many are designed to potentially share one 20A residential circuit with an oven and/or fridge due to possibly being retrofitted into a kitchen built before built-in dishwashers were standard and manufacturers not wanting to create different models for retrofit vs new installs. |

| > share one 20A residential circuit 15, dishwasher manufacturers can't assume the dishwasher is on a 20. |

| ▲ | Scoundreller 5 hours ago | parent [-] | | That's funny. Code in Ontario Canada is that the fridge needs to be on its own circuit. It's funny because we have an extra-big-ass inverter drive fridge that never draws more than an amp or two, even at startup because it's inherently soft-start. Just a waste of copper and a beaker really. | | |

But also helps avoid the case where your coffee maker trips the breaker shared with your refrigerator and you don't notice until the food in the refrigerator is warm. (which was a risk in my previous apartment - the counter circuits were shared with the refrigerator). I think it makes sense to have it as a separate circuit. | | |
| ▲ | brewdad 2 hours ago | parent [-] | | Good point. I haven’t tripped a GFCI in a long while but I don’t actually know if my fridge will lose power when I do trip the GFCI. My guess is that it will since it does have a water line and ice dispenser so probably requires being wired into the same circuit. |

| ▲ | inferiorhuman an hour ago | parent | prev [-] | | Electric ovens in the US have required dedicated 40 or 50 amp circuits for decades per the NEC. Dishwashers, as well, have required dedicated circuits for a while but the 20 amp requirement is a more recent development (although it's probably been at least a couple decades). Kitchens in general have required 20 amp general purpose circuits since at least the early 80s. However the NEC (but not the Canadian equivalent) allows for 15 amp duplex receptacles on 20 amp circuits so home builders looking to save a few pennies often use those. Besides, there are few if any, residential appliances out there that have NEMA 5-20 plugs. Then again hardwiring dishwashers was pretty common up until recently. |

| in traditional times it was customary to buy a few outfits high quality clothing that would last, and wear the same clothes for a week at a time, and then really boil them clean. This is the European market. post world war 2 consumer choice culture in the US led to people buying cheaper clothing but varying their outfits every day and cleaning them (with copious availability of water) with less intensity. once these patterns are established in the market, they become more like customary and it's what consumers expect of their appliances, detergents, etc. |
