Water is filling up but dont stops and start owerfloawing.Indicator lights are ok but durinig owerfllowing lights disapiered.Float switch is ok what stops water.Is it pressure switch?Thank you.

It means that there is a bad water switch on the water fill sensor or stop

Do you mean the "Fill Tank" message? If so, I found the problem to be the magnetic switch triggered by the float in the water tank. Please confirm the message you see and I can provide more details.

Ok, it sounds like your unit might have the same problem mine did. I posted some of my findings in this thread:

http://www.fixya.com/support/t1898311-water_container_full_but_low_indication

Adding a magnet to the float helped for several months but then the problem came back. I found the root-cause to be the 'reed switch' (see picture in the other thread) and when I replaced it, it worked fine. Replacement parts like these are often available through web-sites (e.g. http://www.ereplacementparts.com)

In the water bucket is a float assm. scale forms on the assm. and causes it to stick. Remove the float assm. and carefully remove the scale. Should start working again once done. If not you may have to replace it.

could be one of two things
the machine is asking to be primed or ventilated , where you turn the hot water on till the light goes out.

or is asking for tank to be filled. There is a magnet float in water tank sometimes it stops floating making the machine think there is no water. to check fill tank with water and look to see if float is floating it will be grey/black in bottom corner of tank

float switch is stuck in the "down" position. The unit goes thru a fill cycle and after 1 minute, the board "Looks" at the float swith to "see" if the sump is full. If float is stuck down, it tells the board that the unit does not have enough water and stays in the fill cycle. The compressor will not come on as long as the machine "thinks" there is not enough water. let me know if I can help further

do the following steps: God bless you
To start test program, press and hold both POWER SCRUB PLUS and RINSE & HOLD program buttons, then turn unit on by pressing ON/OFF button. When program buttons are released, lights above them will flash. To end test program, press ON/OFF button.To check program indicator lights (POWER SCRUB PLUS, REGULAR WASH and RINSE & HOLD), press and hold each program button. When REGULAR WASH program button is pressed, CLEAN light also comes on.
To start testing, press both POWER SCRUB PLUS and RINSE & HOLD buttons a second time. When testing has ended and a fault was detected, the following indicator lights will be lit:
POWER SCRUB PLUS = Heater fault
REGULAR WASH = Water filling fault (over or under filling)
RINSE & HOLD = NTC (temperature sensor) fault ? note circulation motor stops shortly after it started during an NTC fault
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil, measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), REGULAR WASH light will come on and unit will continually fill and drain where testing won't be completed. If flow switch (e5) has failed (opened), water won't heat (to 150?F) and water won?t stop circulating. If NTC probe (f2/f4) has failed (opened), RINSE & HOLD light will come on immediately and testing will end shortly after water has started circulating.
If more than one fault occurs, more than one light will be lit.

Hello

Investigate these five areas if your dishwasher won't fill with water:

As water is filling your dishwasher, a float rises along with it. When the float reaches a predetermined 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. Check your float assembly. Replace it if you need to.

The water that fills your dishwasher lifts the float, and when it reaches a certain level, it acts as a trigger for the float switch. The float triggers the float switch to shut off, thereby shutting off the flow of water into the dishwasher. A defective switch may interfere with your dishwasher's filling ability.

Your dishwasher may not be filling with water simply because the water valve's filter screens are dirty and debris-filled. Gain access to your water inlet valve and try cleaning it out. This might be enough to solve the problem. You can learn how to access your water inlet valve in the replace a dishwasher water inlet valve section.

Alternatively, your water inlet valve could be defective altogether. That could be the reason your dishwasher is not filling. Test it for continuity. If it is not functioning as it should, replace it.

Your dishwasher's drain valve is regulated by a drain solenoid. If the solenoid is malfunctioning, it may not allow the drain valve to funtion properly, which in turn could be the reason your dishwasher is not filling with water. Investigate your drain valve and test the solenoid. If the solenoid is faulty, replace it.

probably a bad switch at the float assembly...check that out....probably going o have to replace that. check also for loose or disconnected wiring at the switch. let me know what happens

possibly the inlet water valve stuck open tho this is rare.

disconnect the valve electrically and see if the fault is still present. if so, the valve is stuck open and needs replacing

there is a small float and micro switch behind the LHS cover which if activated will stop the water flow. you will need to remove the top cover(dont forget to unplug from the mains first !). then remove the side cover, you should find a clear plastic unit with a red float in side this maybe gumed up with scale. if so you should clean to allow the float to be free. this float activates a micro switch via a red arm. if this switch is stuck in this will stop the water flow. or the switch maybe faulty.
