WHIRLPOOL GU1200XTLT1 NOT WASHING CORRECTLY

the washer is over filling because the float part is bad see the link below for details Whirlpool Dishwasher Overflows Replace Float W10345285

The float is located just inside the door either on the left or right hand side, it's a simple float, if it's stuck in the fill position then try a gentle push to release it, and make sure nothing is under the float causing it to stick in the filled position.

If this only happens when the machine is turned on,the tube from the tub to the water level switch is pinched or broken. If the clear plastic tube is not pinched or broken,the water level switch in the control console is bad. If the machine lets water through when it is in the OFF position,the water valve where the hoses connect are bad.

Hi

When the Dishwasher won't fill you'll need to check for the water inlet hose, the water inlet valve and the float switch assembly. When the water fills your dishwasher, a float rises along with it. As the float reaches a certain threshold level, it shuts off the flow of water, thereby preventing a leak. Sometimes the float can get stuck in the wrong position in your dishwasher, and it can prevent your dishwasher from filling. Sometimes it can happen due to float valve and on other occasions due to float switch. Inspect the water hose coming to the dishwasher for any blockages. If the hose is not clogged then check the water inlet valve for any clogs, if the water will not even fill for few seconds then certainly the water inlet valve is bad and should be replaced. You can also use a multimeter to check continuity on inlet valve. If you don't get any value on the multimeter then you'll need to replace the water inlet valve assembly. However, if the valve is fine then the float switch assembly should be replaced. Hope this helps... Please post back if you need more information.

Wow a 13 Dec 2009 post. I just started in Jan 2010 and am going thru questions.

Hi and welcome to FixYa. I am Kelly.

Before you go taking it out from under the counter... (at this point thre really is not a need to do so) lets back up a bit.

There are 2 main suspects at this point.

1. The internal Float and Switch assy sticking / inoperative

FLOAT (Item32 of link)
http://www.appliancepartspros.com/partsearch/model.aspx?model_id=262340&diagram_id=104009#d104009

The float should move freely up and down. If the stem gets coated with debris it can stick in the up position. Make sure the float moves up and down while listening for an audible switch "click" as it nears the top position and just as you begin to lower it again.

The Float Switch (Item 30 of above link)
This is the switch that you should hear as you move the float up and down. No click = no fill

and

2. The water valve assy not functioning correctly

Water valve (Item 16 of above link)

The failures of a water valve are:
a. An open coil
b. A clogged diaphram
c. A sticking internal needle valve that is actuated by the coil

I am pretty sure that it is either a stuck float or a bad water inlet valve.

Thanks for using FixYa.

well the timer and the float are the only two things that control your fill cycle,
so since your float is correct ie the rinse cycle
we can only assume that it would not be intermiten it is just a cherry switch

here is the link to the part (timer)
and the breakdown of how to get at it

hi. thanks for the question .if the water would only shut off ,by turning off the water .replace the water valve thanks the appliance doc

The water-inlet valve lets water enter the machine. If this valve is defective, you need to completely replace it. It's usually located behind the lower access panel on the left or right side. It's the device with the main water line (usually copper) from the house, a rubber tube to the dishwasher, and two wires attached to it.

Float switch The float switch is a small electrical switch that's located right below the dishwasher "floor." Above the switch, on the inside of the dishwasher, is a plastic cylinder that floats up as water fills the dishwasher. If this switch is defective, or if the plastic float gets caught or trapped in the raised position, the water can't enter the dishwasher. If the float switch is defective, you need to replace it.

if this helps please vote me a fix ya

Bosch dishwashers have a seperate pump for washing and another for draining. Try making it fill more than once. There is usually a timed fill and the float stops it before it overfills It also might prevent it from washing without enouth water Try defeating the door switch and play with the float during fill. There may be a sensor that won't let it go into wash. Be prepared to get a little wet if it should start up suddenly. A slightly safer way is to fill it with the sprayer from the sink. and see if it will go into wash.
