Question about Dishwashers

1 Answer

The dishwasher will not begin wash cycle. When I press the "start" button, the "heat dry" light illuminates and the "washing" light blinks, but nothing else begins.

    the suggestions provided were great places to start, but after locating the float, removing it, inspecting for debris, and re-attaching, the same thing continues. . . blinking "washing" light. Any other ideas before I call a technician for repair?

Hi

When these lights flash on your machine it is actually transmitting a code which can be read by a technician to help determine where the fault lies.

However there may be a simple fix that you can check on yourself before resorting to service repair. I am assuming from your description that your machine is not even filling with water when you go to start the wash cycle.

As always when working on any electrical appliance make sure the dishwasher is disconnected from the mains before carrying out any work to it.

As water is filling in your dishwasher a float rises along with it. When the float reaches a predetermined level it shuts off the flow of water by activating a switch thereby preventing a leak. Sometimes the float can get stuck way up in the wrong position in your dishwasher and the switch remains activated therefore preventing the fill of water to the machine.

If the float is stuck and has not returned to the fill position it will prevent your dishwasher from filling. Therefore the first step is to check your float assembly (see below) and replace it if you need to.

Your float assembly is found inside the dishwasher's tub, on the bottom. 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. The float in your dishwasher needs to be able to move up and down freely. If it should happen to get stuck, it could interfere with your dishwasher's ability to fill.

To inspect the float assembly - open the dishwasher door and remove the lower dishrack. If your dishwasher has a cover over your float assembly remove it. The cover over the float will either be clicked in place or held by a screw.

Lift the float and let it drop several times. Its movement should be entirely unrestricted. Now remove your float. You are looking for any obstruction that may be hindering its movement. Floats usually snap into place. However, if you are unable to remove yours just by pulling on it, it may be connected to the float switch. If this is the case, you will need to disconnect it to look for debris.

If you are unable to find any debris that is blocking the float switch, the float switch itself may be at fault. - You will need a multimeter to test this.

You can gain access to your switch by removing the lower kickplate panel located just below the dishwasher door. This panel is usually held in place with a few screws. You might need to open the dishwasher door to gain access to and remove the screws. The door will have to be closed again so that you can remove the panel.

A dishwasher's float switch will sit below the float assembly previously mentioned. So when you find your float assembly inside your dishwasher your switch will be located directly below it in the access area.

There are going to be two wires connected to the float switch. They are connected with slip-on connectors. Its a good idea to label these wires so that you are able to correctly reconnect them later. Grasp the slip-on connectors and pull firmly to remove the wires from the switch. Do not pull on the wires themselves. You may want to use a pair of needle nose pliers to help you.

Use your multitester 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 your switch fails either of these tests, you should replace it.


Other possible causes of water failing to fill are;
1) Water Inlet Valve Blocked
2) Faulty Door Switch
3) Failed Drain Valve Solenoid

If you find your problem is resolved please remember to accept and rate my answer. If the issue remains unresolved feel free to post up a comment and I will be glad to continue with the troubleshoot. Many Thanks.

    Hi



    If the float is Ok and you have tested the float switch and it checks out Ok - in your case I would next look at the water inlet valve.



    Make sure Appliance is unplugged before inspecting.



    To access the inlet valve remove the lower panel located beneath the door. The panel is usually held in place with two screws either above or below the panel. It may be necessary to first open the door to the dishwasher to reach the screws over the panel, then close the door to remove the panel.



    The water inlet valve can be identified by the water hoses connected to it.One hose will lead from the valve to the pump/motor assembly in the center of the dishwasher.



    Check that the hoses are securely connected to the valve and that there are no kinks in the hoses which could restrict water flow.



    There are two wires (four, if it has two solenoids) connected to the water inlet valve. Label the wires and connections so that you can properly reconnect them later. The wires are connected with slip on connectors. Firmly pull the connectors off of the terminals (do not pull on the wire itself). You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If either is corroded they should be cleaned or replaced.



    Use a continuity tester or multitester to test for continuity. Set the multitester to the ohms setting X1. Touch one probe to each terminal. A reading of infinity indicates a bad solenoid that must be replaced. Different brands and models will have various measurements, but the valve should show some resistance if it is functioning properly. If your valve has two solenoids, test the second one in the same way as the first.



    If the solenoid is working properly, but water leaks through the valve even when the dishwasher is off, then the valve itself is the problem. Debris may be preventing the valve from closing. If the valve cannot be cleaned, it will have to be replaced. The valve can also fail mechanically. So even if it passes the electrical test, it may still require replacement. If you have ruled out all other possibilities, go ahead and replace













    google_protectAndRun("render_ads.js::google_render_ad", google_handleError, google_render_ad);
    the valve.

    Finally - just to add one thing which is a very simple check and given that your washer is illuminating the heat dry light there is a possibility that your heater element is faulty or if your lucky the thermostat has simply tripped. This may well prevent the machine from starting if it is detecting this as a fault. This is a very easy fix and has got to be worth a shot.



    Again - Make sure appliance is disconnected from the mains.



    Remove the bottom 2 screws in the panel giving you access to the underside of the machine. You don't need to remove the dishwasher. If you look inside the dishwasher you will see the element and on the left hand side near the front the thermostat.

    Underneath the thermostat is a small red button - reach in and push this - if it clicks - you've fixed it!

    Total cost zero!

    The heating element itself would need to be checked with a multimeter to determine if it is faulty as would the control panel which is the other potential problem with your machine and this really is tech territory.



    If these checks fail the other inspection would be the latch mechanism to ensure it is operating the door switch correctly and of course the door switch can be checked with a multimeter. Both of these can prevent machine starting.



    Failing all of this its technician time I'm afraid!



    Hope this answer has helped and please don't forget to rate. Many Thanks.

Talking about a kenmore 665.16389300 dishwasher. the "normal wash" button is blinking, but none of the other buttons seem to work and the cleaning cycle will not start when i press the...


Hi
Open the door. Within 3 seconds press the following sequence --Try pressing normal wash, heated dry, normal wash, heated dry, normal wash, heated dry three times within 6 seconds and then press cancel to reset the dishwasher. If that doesn't help then try pressing Saini Rinse, Heated Dry, Saini Rinse, Heated Dry, Saini Rinse, Heated Dry or Saini Rinse, Air Dry, Saini Rinse, Air Dry, Saini Rinse, Air Dry 3 times in 6 seconds and then the Cancel Button. Close the door and press Cancel.
Blinking lights would stop and should be able to use your dishwasher normally. If the light is still blinking try and reset the power to the dishwasher and try again. If still the light is blinking then check for the connections on the keypad, it may be due to moisture or shorted connections on keypad. Hope this helps... Please post back if you need more information.

Clean light won't turn off, new wash cycle won't start.


Press these buttons in succession, within 5 seconds: high temp wash, air dry, high temp wash, air dry. If the sequence is entered properly, all of the control panel LED's will illuminate simultaneously. Once this happens, press the cancel button twice. Now you should run a complete cycle again. If the dishwasher actually has a problem, it will fault again (means the unit isn't heating properly). If not, it's business as usual.

Kenmore elite model 16574


press (high temp-wash) button and then ( heated dry)
do that 3 times in that order within 5 seconds. So it looks like this:

(high temp-wash) ( heated dry) (high temp-wash) ( heated dry) (high temp-wash) ( heated dry)

That will start a short diagnostic cycle (last about 2 minutes) that will clear the blinking light and allow you to use the dishwasher. If the light comes back, your drying cycle has failed and you will need service.

Watch the light closely. If it blinks 7 times then pauses, this indicates a heater or door latch issue.
Press the following buttons in sequence: Hi Temp Wash, Heated Dry, Hi Temp Wash, Heated Dry, Hi Temp Wash.
If this doesn't work, check the tech sheet. (should be stuck to inside of the bottom toe panel)

All lights should illuminate then a diagnostic sequence will start.
Listen carefully, as soon as you hear the water begin to fill, open the door and feel the heater. if cold, check the heater for continuity (should be around 10ohms)
Also, bend the door catch on the dishwasher tub downward, this will engage the door latch better. Don't bend too far as it will hit the door while closing.
