Correcting "dumbed down" hot water flow

[thefixer]

I believe I am correct on that. After searching around with the part number for that valve, I see it listed on some sites as "Bi-Metal water inlet valve".

No PCB, but the water valve is described as "with bi-metal" (thermostat).  It's reasonable that the wiring connection is to the timer being that temp selection is there.

Could be this diagram.  Seems a given machine may have a bi-metal-equipped water valve, or not.

Yep, didn't notice that temp select was part of the timer. That is a bare bones washer. How nice. Just leave that connector disconnected if you don't want your washer deciding how hot your hot water will be.

Hi Eric,

 

Thanks for all the info... and yes you are correct.   That is the correct wiring diagram DADoES, I just opened the console to look at it.  I took photos, but cannot post them until I get home.

 

I guess the water temp from the little 30 gal electric water heater isn't hot enough to cause the bi-metal switch to trigger, because I've never witnessed it turning off or cycling the valve solenoids.

If I'm interpreting correctly, timer contact 12 is rinse temp so is always cold.  11 & 15 are wash temp.  11 for hot, 11+15 for warm, 15 for cold.  So seemingly the bi-metal circuit comes into play only on a hot fill, presumably to add cold if the bi-metal triggers on "too much" heat.

I posted a "walk around" in another thread that might appeal to some.

Hey Tec.

I do not advise doing that, that's actually against plumbing code. (At least, in Canada it is.)

You need a proper mixing valve which prevents thermal siphoning of cold water to hot water and vice versa.

A friend of mine had a portable washing machine which he used in an apartment building with an older sink and he used something like that.

The problem was, as a result of his hack, every toilet in his building was flushing with hot water. Not something that is very desirable.

The solution? Using both taps only when the washer is filling for the wash, then leaving the cold water tap on for the rest of the cycle and shutting the hot water tap off.

I'm going to say again, please do not do this unless you understand the consequences. Please use a proper mixing valve with proper check valves.
