exactly, the timer will advance to the wash cycle whether it takes in water or not

All models?

Seems like a design flaw.

look at it this way, lets say your dishwasher is filling great no problems but then your float somehow gets jammed up or the switch fails. The dishwasher continues to fill and fill and fill because there is no way for it to shut off because your switch is stuck in the normal closed position. Disasterous. not such a design flaw after all.

Maybe so. Still seems like there would be a better way.

Seems like a timed inlet valve independent of the float valve would stop a continuous flooding conditon.

I'm thinking as in an icemaker inlet valve. Run 5 or 6 seconds, or whatever, and shut off. Looks like a time could be set on a diswasher similiar to this.

not exactly sure what your point is , I'm thinking you do not understanding how a dishwasher fill circuit works. there is no float valve, all it is is a float and a micro switch. Timer or circuit board engages sending power to float switch,water valve gets power through float switch, water fills into tub, water raises float , float trips micro switch cutting power to valve. Plain easy and very effective you have double protection in case of failure.

No, not all models. Mine (LG) will fill until the time expires. If the fill level sensor is not satisfied, it will go "ding ding ding ding ding ding ding ding ding ding ding" to let me know it is on strike until I open the door and close it which resets the fill timer.

exactly. At least I do not get the surprise of the machine having had run without enough water to actually wash the dishes though. That would tend to piss me off as well, I suspect the heating element not being covered with water, if needing to run, would be subject to damage as well.

Thanks everyone for the advice. I've tried it all.... Cleaned the filter inside, flushed the pipes and cleaned the screen. But all I have to show for it is a huge bruise on my elbow. The dishwasher is running better, but still not great. I think I might need to call in a plumber, or get a new dishwasher. I learned a lot though!

Hehehe, actually, I know it is not a float valve. Not sure why I kept using the word valve, I did not have one pictured.

They do get stuck, and I believe there should be a better way to stop the flow.

I admit I am not that familiar with dishwashers as I fooled with washers, dryers and fridges more. Not really in a professional way. Buy them , fix them, and sell them for the most part. That was years ago.

Didn't come across a lot of dishwashers. The ones I did come across, I did not think were worth the time and effort to fix.

Listen to the H/Wman, don't buy a new d/w-they're nowhere near as good as the old ones-if you have at least 20# pressure to D/W-your valve[fill] is bad, common problem....just to add; the float sw is only for safety, [to H/W point].. most older d/w used only the timer for fill. there is a flow washer in the valve to accomodate different water press'. some d/w do time out on the float sw-older Maytag for eg but that's a design thingie as they use current flow through the mtr to control the det cup trip mech. it also ensures on the first fill if the tub is cold and water hot you won't get a surge coming out the door. over the years some manf used a press sw to control level but that basicaly fell out of favor..many of todays electronic E D/W use sensors, current flow, turbidity or back to the old press sw to determine fill-your LG beep...so now we're saving water? but the dish' aren't clean--????

Hmmm? The heating element on mine only comes on after all the water has been pumped away. It dries the dishes!
For washing, hot water must be supplied from a hotwater heater.

Was there any sign of sand in the valve or filter?

I guess you would be right. I forgot about that.

Mine heats the water if it is not up to proper temp or I use the "sanitary wash" where it heats it to "will cause damage to human skin" temp.
