Water dispensing into ice maker won't shut off

There should be a float or electronic water level sensor that will tell the water to shut off, if it has calcium from the water on it or the float is damaged it will keep sending water until manually shut off(pull the plug). I would look for a water level sensor of some sort and clean or replace it. If that doesn't work it could be a sticking water fill solonoid which you should then replace

Switch dishwasher on and starts up ok but when it comes to pumping water in it stops and does not do anything else.


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.

The dishwasher is not cleaning properly, I have used the finish dishwasher cleaner twice the salt is full and rinse aid is full. I have taken the drainage bits out and wash properly, but everything seems...


If the water inlet valve is fine and it fills with water then the issue seems to be with the float switch assembly that is bad and should be replaced. Float assembly is found inside the dishwasher's tub, on the bottom. The water that fills the 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 dishwasher's filling and/or draining ability. Use voltmeter to test the switch. Set the device to the ohms setting x 1. Take each probe and touch them to one switch terminal each. This should produce a reading of either zero or infinity. Continue to touch the probes to the terminals, and press down on the switch's button. The reading should change to the opposite extreme. If the switch fails either of these tests, you should replace it. Hope this helps...please post back for further assistance.

Water will not fill the dishwasher, it runs but it will not fill with the water inlet plugged?

Hello there

The most common causes of this problem are a defective water inlet valve or a stuck float switch. The float switch sits under the dish racks and sends a shut-off signal to the dishwasher when the water level is high enough. Make sure you only use a Maytag-compatible replacement if you have to change out your dishwasher's float switch or water inlet valve.
Difficulty: Moderate Instructions Things You'll Need:

  • Owner's manual
  • Screwdriver
  • Scrub brush
  • Replacement parts (if necessary)

  1. 1 Shut off power to the dishwasher from the home's circuit breaker box. Remove the lower rack from the inside of the dishwasher.
  2. 2 Check the water inlet valve to see if it clogged or broken. Replace the valve if you notice any problems and test the dishwasher again. If it still does not fill, proceed to Step Three to troubleshoot the float switch.
  3. 3 Consult your owner's manual to find the location of the float assembly. Remove the cover, if applicable to your dishwasher. There may be retaining screws holding the cover in place or it may just snap off.
  4. 4 Hold both sides of the float while you raise and lower it several times. The float should move freely without binding or catching on anything. Disconnect and use a scrub brush to clean the float if you feel any resistance.
  5. 5 Reattach the float and test its movement again. If it is still not moving properly, replace the float.
  6. 6 Replace the lower rack of the dishwasher and turn the breaker switch back on.

1 Answer

Hi I had a leak in my water line to the ice maker. I replaced the line, now it will not make ice. Water is not going into it.

The fact that it was running fine before you replaced the pipe indicates the problem is with either the connections on either side or possibly the pipe is kinked or the wires from the solonoid pipe have been accidently moved. Firstly Dissconnect each end and see if pipe is clear and round on both sides. if good, blow into one end and see if blowing is possible. Then replace one side of pipe onto solonid side. With the opposite end open activate the valve. Water should come out in about 3 seconds. no water = vave not activating.If you are not farmiliar with mains power i suggest you dont test solonoid by yourself. Get help. Put a lead onto the solonoid and plug into mains. Switch on briefly and see if sol. activates with water exiting on the open side. If so switch off and reconnect pipe onto connecter that old one came off from.Once connected, have someone check inside at the icemaker while you put power on to the valve again.If water comes out, switch off- pull plug out then reinsert solonoid wires back onto the sol. Must work. Very seldom will the valve be a problem. Another thing you could do is to activate the test button function.

Bosch Exxcel Auto option

There should be a float switch inside the dishwasher sometimes these get hung up on the full position which in turn keeps the solenoid from allowing the water to come on. remove the bottom rack and check to see if this is the case. Dislodging the float should fix the problem. If not listen to see if the solonoid Clicks when you turn the cycle to fill position if not it could be either solonoid or the timer. if you hear click and still no water check strainer in water line could be clogged or water is turned off some where.

Power fine, but no water filling the tub

difficult not seeing the valve firsthand but if you could connect a tester to the solonoid and confirm that there is power on the terminals, then you know there is an issue with the valve. typically, if you have a leak, it to will raise the float and shut off the valve.
