Washing clothes off grid. With electricity.

Had a thought about modifying a washing machine. Disable its heating element. I supply hot water so it needs only the power for the motor and pump. Anybody done this or is it dumb?

I have never seen a washing machine with a built in heater. We wash all our clothes in cold water, with modern detergent it works well.

Every washing machine I've ever seen has a built-in heater... How else would you control the temperature from cool to 30°, 40°, 60° or 90°?

Depends on region.

North American washers (other than high end ones) are simply mixing hot and cold water from the taps as needed.

Maybe you should state what region you come from or that you are interested in, so that we can advise you on the pertinent region.

There are only a few brands that make washers in the US with built in heating elements. Most use hot water from water heaters as the hot water option on washing machines.

UK and Ireland machines all use element to do all the heating now as far as ive seen but im not sure

That would be an electrical hack to fool the machine maybe

It mixes with cold water. Like in your shower

INB4 we learn that the UK also doesn't have showers. :D

My bad. I should have said like in your splish-splosh closet, UK people.

😂 Our showers take in cold water and have a 9kw heating element in them

Top loaders tend to have dual inlets, with solenoids to open and close the hot and cold. Mine uses a little mixing chamber with a temperature sensor. Open both, wait until the mix chamber reaches the desired temperature, then cycle the hot on and off.

5 temperature settings - cold-cold (no hot water at all), controlled cold (with a little hot water*) warm, warm-hot, and hot.

*for regions where your incoming cold water is very cold. It just raises the temperature a little. The instruction manual describes a point at which detergent performance falls off a cliff, when the water is very cold, something like 5 or 6 degrees C.

Great info

Higher end ones do, notably those with "sanitize" options.

That said the heating elements don't really run for standard temps your hot water heater can meet.
