You could have a Cold Water inlet screen clogged. Turn off the Cold water supply to the machine and remove the cold water connection at the washer.
Take a pair of needle nose pliers and remove the remove the Cold Water Inlet screen as shown if it is clogged flush clean then reinstall and turn on the Cold Water supply valve.
I have my back Console cover remove for other work. The H/C water valve solenoids are seen here.
If you still have no Cold Water the valve may be stuck closed, or you have no 120VAC being applied to the Cold Water valve.
If you have 120VAC applied to the valve and no water flow the valve assembly will have to be replaced.
You can go into service mode and turn the Cold Water Valve and see if you hear it hum.
Enter / Exit Service ModeTo enter Service Mode press the Enviro Plus and Spin
Only keys (simultaneously) for three seconds or until the control beeps
the display will read 00
Now got to page 16 of the Service Manual Board Output Test While in Service Mode, pressing the Delicates key will begin the Board Output Test. This test turns on a specified output after a key press.
Now press the Spin Only key…..did you hear the Cold Water valve hum. If so the 120VAC is applied from the Control Board and the valve may be stuck closed. If this is the issue the Water Valve inlet assembly will need to be replaced. Keep in mind I’m a technical owner and would double check the 120VAC on the Cold water valve solenoid before replacing. I’m just providing general info.
A work around if you are a Cold water user only like me is to reverse the hose connections at the washer hot to cold, cold to hot then select hot water fill. You now are filling the washer thru the Hot Water Valve assembly with the cold water supply source. The p/n from searspartsdirect.com is 12002242
for the valve assembly.
If you need to replace try a local parts supplier to make sure your 120VAC connections are the same as the original Water Valve Inlet assembly.
The Service Manual will step you thru replacement if this is required.
Good luck and post back if you have questions…….Rich
