Wff 2000. Why is prewash light flashing 7 times, then pausing?

SOURCE: prewash always flashing

yes i had a similar problem the prewash light kept coming on mid wash cycle and eventually stopped taking in the water just bypassing it straight to outlet without filling machine. i found if you remove the pump at the rear of machine and disconnect hoses there was a build of lets say deposits leading to a sensor through a opaque plastic connector to the top of machine . after cleaning the hoses thoroughly and removing all the crud machine worked as it should do, hope this helps

HI
Most washing machine timers are digital or mechanical. The timer controls most of the operations of the washer: water level, tub filling and emptying, length of cycles, and cycle setting sequences. For this reason, any repairs to the timer should be made by a professional service person. However, there are a couple of checks you can make when you suspect the timer is faulty -- you may be able to install a new timer yourself.

Step 1: Unplug the washer. To access the timer, remove the control knobs and the panel that covers the controls. This may be a front panel, or access may be through a panel at the back of the unit. Carefully examine the wires that connect the timer to the other parts of the washer. If the wires are loose or disconnected, try pushing them into position; they usually fit into their terminals like plugs. Use long-nosed pliers to avoid breaking the wire connections -- never pull a wire by hand.

Step 2: To test the timer, use a VOM set to the RX1 scale. Disconnect the power leads to the timer and clip one probe of the VOM to each lead. The VOM should read zero if the timer is working. Since the timer is a multiple switch, turn it through its cycle and test each pair of terminals in turn. The meter should read zero at all of these points. If one or more readings are above zero, the timer is faulty and should be replaced.

Step 3: To replace the timer, unscrew and disconnect the old one. Install a new timer made specifically for the washing machine. If there are many wires on the timer, have a helper hold the new timer next to the old one as you work. Disconnect the old wires one at a time, connecting each corresponding new wire as you work, to make sure the connections are properly made. Or, draw a diagram showing the connections before removing the old timer. After all the wires are connected, check the connections again for correctness and screw the timer assembly into place.

Hi,

This machine was made by Whirlpool and the flashing clean light is a common error code for them.If the clean light is the one flashing then your dishwasher could have a heater circuit problem (depending on the age) or this could simply just be water colder than it is used to getting.

Repeatedly press the Heated Dry and Hi-Temp Wash(scrub) which ever yours has until all the LED lights come on, press cancel twice and try the dishwasher again making sure to run the water at the kitchen sink till it is hot before starting the dishwasher, if this trips and locks you have a problem with the heating element, or temp sensor.
Press the heated dry button followed by the normal cycle button, and then repeat once. You should see all of the lights come on for a second or two, and then the dishwasher will work again.

If you haven't already, take a look under the kick plate in front to see if there is a schematic tucked in there somewhere. Whirlpool has put their diagnostics for specific models on these.
I don't have the specific repair manual for you model.
So, if the above combination does not work here are two more that have worked for me.

HiTemp Wash + Air Dry + HiTemp Wash + Air Dry in less than 5 sec
or
Hi Temp Scrub/Scour + Air Dry + Hi Temp Scrub/Scour + Air Dry in less than 5 sec


Let me know, if you need further assistance.


Hope i helped you.


Thanks for using ' Fixya ' and have a nice day!!

the error display may have to be cleared from the control manually. That can usually be done by putting the unit into diagnostic mode by pressing the key sequence 'Heated Dry, Normal, Heated Dry, Normal' and then pressing cancel.
