Samsung sw50usp washing machine. cold water only doesn't flow into machine.no blockages in connecting hose from tap to machine.if set on hot water only machine does fill up.

i don't know. for drain, if in a stand pipe, it seems the drain pipe may be partly blocked. if hooked hose runs into sink, sink drain may be partly blocked, if drain water comes out too fast, consider a tywrap to hold a small towel around hose end to stop splashing. do not block the hose outlet.
low hot water flow may indicate supply hose is restricted. please shut off both cold and hot water supply . remove and inspect hot water hose for blockage. some hose have a screen filter in the end that needs cleaning.
if practical, connect the hot water hose to the hot tap and run water into sink to test for a good flow.

yes
it is connected to the bottom of the tub by a small hose
it sits up top and as the tub fills , air pressure acts against a preset spring tension and switches the water solenoids off at the same time it starts the wash
the problem is probably the water inlet solenoid / valve that is not working or the diaphragm is split
to test , change over the cold and hot water hoses at the taps and press the hot water button
if the flow stops at the required setting it is the cold water valve unit

problem in hot water tap
hot water solenoid not activating to let water in
to prove either switch the hoses on the taps and press cold water wash
that proves the tap
then press hot wash and that proves the solenoid

Hi just read your posting.Now just a couple of questions.What water temp have you set the machine for,Is it cold,cold or another setting.Have you got the cold hose going from the cold tap to the cold water valve on the machine with is marked with a C and the same for the hot which is marked H.Please reply with answers to all the questions and I am sure I can help you with this fault.Looking forward to your reply.

Hi and welcome to FixYa, I am Kelly
Turn off the water at the wall connection remove the hoses noting the positons of HOT and COLD. Then clean the inlet screens in the water valve. (lift out by using a knife blade on the outside of the screen) Wash the screens by rubbing your fingers ofer them under slow running water then reinstall them.

Before you start try a hot wash.. and then cold wash to see if either has water coming into the machine. If it works there is a way to back flush the water valve using a warm water wash. You remove one hose and stick it in a bucket. Turn ON the other hose and let water flow into the bucket while gentily tapping on the hose connection with a screw driver HANDLE. Reverse hose connections and repeat hose in bucket and tapping on hose connection. Reconnect both hoses then try HOT and COLD wash fill cycles. Let me know what happened.
Thanks for choosing FixYa,

The best way to stop your situation is to connect the hot hose to the hot tap. A hardware store should have a female cap you can screw onto the back of the machine, or get a male plug, same thread as a tap and plug the end of the hot hose. Elevating the end of the hot hose may help..It's normal for water to flow out the hose as you've described...Good luck...Nomess

Hi and welcome to FixYa. I am Kelly. This sounds like either the hose or the water inlet valve screen is clogged. Possibly the pinhole inthe diaphram itself of the water valve. Here is what you can do.

1. Get a bucket
2. Turn off BOTH water valves at the wall.
3. Remove the HOT water connection at the water valve. Then check the inlet screen for debris. You can remove the screen from the water valve by using a knife blade on the very outside edge of the screen tugging outward. Hold the screen up to the light check it for debris. If it is dirty wash it under a light flow of water in the sink. DO NOT reinstall just screen just yet.
4. Use a measuring cup or something similar to catch water at the water valve HOT connection. Select a WARM wash cycle and start the wash cycle. Let the water flow into what ever it is you use to catch the water exiting the HOT water connection.
Tap on the cold water hose connection to try and free the debris inside the water valve as the water is flowing. Do this a few times until you have let water back flow through the water valve for about 20 seconds.

Machine timer off.

5. Reinstall the inlet screen in the water valve and reconnect the hose. Place the HOT water hose in the bucket and start the WARM fill cycle again. This will flush the hose.

Machine timer off.

6. Reconnect the hose at the wall connection and turn on the water at the wall.

7. Select HOT wash and test water flow. It should by now be (fingers crossed) flowing.

You can repeat the above for the cold water side if you need to.

Thanks for using FixYa,

hi from uk assuming you have checked the stop taps are turned on ? there is electrical supply to machine? check plug fuse ? machine req's electric to function the inlet valves hot/cold at the rear of machine where the hoses fit to valves if all ok above? then turn off the supply hoses where they connect to house hot/cold supplys (under sink?) then disconnect hoses from stop valves then with a suitable bowl/bucket undrneath each stop tap slowly turn each one on a little to see if water is flowing ? if so? reconnect hoses if your stop valves are not allowing water flow ? you will have to check the stop valves for operation and possible blockage ? follow the above checks as suggested in order and come back with any info or success ? or if you req further d i y help best wishes

take it back for a new one
