Ok Bill thanks for that, The problem here is going to be one of a couple, Either the valve screen is clogged on the cold side or the valve on the cold side has failed.
Pull the machine out from the wall, shut the water off then remove the water lines from the valve (where they hook up at the back of the machine) look inside the cold valve at the screen, If it is clogged pull the filter screen out then clean it. Try the machine again.
If this does not clear up the problem then the cold valve has failed and will need to be replaced.
Below I have included a link where you can buy the part, I like to purchase my parts from this supplier because they offer a 1 year warranty on all their parts plus they allow you to return them even if they have been installed unlike others.Click here to order the valve
