No power to the main water valve during cycle.

kindly cehck the water inket valve Sometimes, the valve might not open fully during a cycle, causing water flow issues or it may be clogged

Sears Parts Direct is one source of the parts diagrams, https://www.searspartsdirect.com/model/1vc37q1bdj-003204/lg-wm3987hw-washer-parts . See the Dispenser assembly parts diagram for the water inlet valve. If you can watch the entire cycle, try turning off the shut-off valves for the washer inlet hoses after the rinse cycle and before the dry cycle starts. Water should not flow into the washer/dryer with the shut-offs closed.

I've seen inlet valve solenoids fail in the open position or in the closed position. I've never seen a control board that sent open messages randomly. (Sometimes, there is damage to the control board or corrosion or damaged wiring that stops the control board from sending the open/closed message to the solenoid.)

I hope this helps.

Not sure but I think it is normal, not even sure it is a countdown timer - illustration shows just a single large knob which presumably is the main programme selector, which is basically an electric clock that keeps pausing whenever the washer is busy filling, heating, etc. and moving on when it is time for the next function.

Modern cold fill, water economy washers tend to take much longer to complete a cycle with the shortest programmes taking more than an hour...

Does you tub have the air system installed? If so you may have the air system advanced function. There are two types of air system advanced functions.

1. With water level detector: A 30 second Drying cycle Will automatically start 20 minutes after the control has detected there is no more water remaining in the tub.
2. With out water level detector: A 30 second Drying cycle Will automatically start 20 minutes after the complete stop of the blower.

If you have the first type this may be normal or the water level sensor may be dirty or faulty.
If you have the second type it may be a control board problem.
. Hope this helps.

It is possible that the machine does not start off the cycle because there are errors or back feedback from the inputs. For the program to start up the main program controller must initiate the INLET valve to open up and allow water to flow into. If this does not happen then the voltage at the inlet valve must be checked or the fault relates to no voltage from the controller. This means the controller is a suspect.

If the water flows then the flow should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. Once the water comes into the system the WATER LEVEL SENSOR - normally a pressure switch- must activate at the preset/chosen level to give the signal to the program controller to switch on the motor. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor for rinse and wash.

Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the dry spin with the drain valve/pump activated so as to drain off all the water from the clothes during the spin.

Make sure that a fault in any of the cycle will relate to the specified action, so check the command from the program module and then the executing device be it the valve or motor or pump.

E62: Overheating during washing

E12 means a problem filling on dry cycle.

Unplug the appliance, take the top off and check that the plastic condenser below the fan is clear and clean.

If this is ok, the most likely fault is the triple valve isn't opening properly to feed water into the condenser.

It may be that a power off and on is all that is required to make the valve work.
The worst case would be that it's a fault with the main control board.

If you have access to and can use a multimeter you could test and make sure that 240 volts was being supplied to the valve when it goes wrong. This would narrow the fault down.

Ive had it many times when during use the valve fails. So at first it works ok and during use thats when it fails.

What you can do is set it going and say after 20 mins or so unplug it and meter out the dryer coil on the fill valve. Its the green coil. What you will proberbly find is the coil is open circuit.

If so the valve will need to be replaced and it should be back to normal then.

I have exactly the same problem. I am currently getting around the issue by letting the machine do the washing then at the end of that cycle do a manual rinse cycle.

Hi

Kindly check for the following :

Check for hose kinks or food plugging drain hose. Start at the drain port exit.
Check the check valve and drain hose for debris.
Check pump motor for reversing during the pump out make sure the dishwasher is pausing between the wash and drain cycles letting the pump/motor reverse for the drain cycle.
Check pump motor assembly for a drain solenoid, during the pump out make sure the solenoid makes that distinctive "clunk" noise
If you have recently installed a new garbage disposal, check knock-out plug at connection.



Check pump impeller for damage.
Check that the water inlet valve isn't seeping fresh water into the dishwasher when off.

Please contact for any further clarifications.

A Fixya Rating would be appreciated if.

Thanks

Hello bckp,
Welcome to Fixya


If your dishwasher does not run or stops during a cycle
Is the Start/Resume indicator flashing? Opening the door or
interrupting the power stopped the cycle. Close the door and
press START/RESUME.
Does the Start/Resume indicator flash 3 times when you
press START/RESUME? The dishwasher is waiting for you to
open the door after the last cycle. Open and close the door,
then press START/RESUME.
Is the door closed tightly and latched?
(NOTE: On models with a dual-digit display, the control
displays “- -” during a cycle if it believes the door is not
latched.)
Is the right cycle selected? Refer to the “Cycle Selection
Charts.”
Is there power to the dishwasher? Has a household fuse
blown, or has a circuit breaker tripped?
Has the motor stopped due to an overload? The motor
automatically resets itself within a few minutes. If it does not
restart, call for service.
Is the water shutoff valve (if installed) turned on?
It is normal for certain cycles to repeatedly pause for several
seconds during the main wash.

If the dishwasher will not fill
Check the overfill protection float that is able to move up and down
freely? Press down to release.

Let me know if any of these procedures helped you?

Please remember to leave a rating.

Do you hear any noises during the cycle, does water come in and drain out ?
