Why do new GE dishwashers open the drain solenoid during the fill cycle and right before entering the dry cycle with the motor shut off? I can't figure out why, but my curiosity is driving me mad lol.

New GE DWs ?

What models are you talking about, only the basic builders models have a drain valve the last decade or so and because the DV coil is only an intermittent duty coil it could only be energized for about 15 seconds at best, so I don't see why this would be driving anyone MAD, LOL.

Perhaps not new in the design sense, but new in the sense they are somewhat different (ie now come with a filter, use less water than several years ago, ect).


The drain solenoid engages for about 15-20 seconds on some fills and after the motor shuts off for the last pump out. I can post the tech sheet if need be.


Its not the sound that driving me mad (I've always liked the snapping), but my curiosity. I have to know why its doing this- the purpose- the reason lol- as I can't see why it would need to.

Possibly a timer thing? Maybe to not have more then 1 switching action happening at the same time? The difference you describe should be exactly 1 timer increment...

Its in the tech sheet- the solenoid engages during several fill cycles and after the motor shuts off.

My guess is that it's to create vibration to "unstuck" the filter soil chamber check ball.
Not to say it always sticks but maybe it's their insurance policy in the programming.

I didn't know

those were still in production. Simple enough, and inexpensive for apts., etc.
Any uplevel model today has a separate drain pump.

Those racks with the dish loops rather than tines.  Reminds me of my 1980 Kenmore.  Talk about the epitome of cheap.  The racks look like what I've seen in Chinese produced products.

@John300- that has to be it- and makes perfect sense! I know for a fact the motor needs to shut down because the running motor actually keeps the drain flapper open even when the water has all been pumped out. GE took out that second drain assembly spring. I guess the same happens with the sump ball- but from the pressure of the drain hose water pushing back. Interesting theory.


@Appnut- cheap- but durable. IMHO those looped tins are better than the straight ones. Much harder to bend out of place, and dishes fit better to be honest. On my current Maytag with straight tins the plates roll when you pull the bottom rack out. Over all these new GEs are a significant improvement from their late 90s early 2000s models which are complete trash performance and durability wise.

Pulse

They likely pulse the drain valve to make sure it moves freely and can seal when the pump starts. Otherwise it might drain some of the precious bath water...

My Boyfriend has one of these. I was listening/watching it last night at his place after we loaded the dinner dishes. During the fill, you will hear a snap f the solenoid. Listening to it, it would seem that it is flushing any remaining dirty water from the sump before allowing it to fill completely for the next cycle.
