Cold water trickles, hot water fills fast as normal

If you switched the feed hoses over and the problem reversed itself, cold has gone from fast to slow useing the hot water pipe and hot from slow to fast useing the cold water pipe then this would indicate a fault in the water supply from the hot pipe. What sort of pressure is coming from the hot pipe when not connected to the machine but filling in to a bucket? Are there any shut off valves before the pipe that supplies the hot water? Are they fully turned on? Any kinks in the feed pipe for the hot water? Has the hot water feed pipe collapsed internally? Change the pipe to check this and not just at the machine side.

Turn the cold water off and remove the hose at the machine. You will find a screen located there and you will need to clean it out.

regarding your filling problem , most washers have small screen filters at the water intake, take your hot and cold hoses of of your machine and observe the fittings on the machine you will likely find the filters there they are just a mesh screen, remove them and clean , then reassemble this should solve your slow filling problem

your hot water goes through the water heater so contaminates settle in the heater. the cold does not, there is a screen inside the fill valve where the hose hooks to the valve on the machine. if this in not plugged then the fill valve will have to be replaced. because of the build up of contaminates..

Hi, You need to remove the fill hose and see what is plugging the inlet valve screen. This should make a guge difference.
Please let me knwo ig I can assist you further.

Thanks

turn off water valves at wall, disconnect the supply hoses from the washer. where the hoses connect to the washer, there is usually a stainless steel screen/strainer inline on both the hot and cold inlet. corrosion on the cold side is pretty common. Menards, Lowes Home Depot stores sell the replacment screeens.

hot/cold selector switch replacement imminent.

remove fill hoses and inspected for debris or cloggs ,,,,

There are filter screens where the supply hoses connect to the washer. On some brands there is a screen where the hose connects to the water valve at the wall. The screen is probably full of sediment.

its in your cold water line valve to the washer if it works good with hot water the valve are incoming line being blocked when you turn it on the pressure comes in fast then when pressure is gone water slows down so when its off the pressure builds back up it runs fast then slow
