Samsung 650p washing machine goes to water reuse when starting any wash programme.does not even fill water.

Water inlet valve. Check it for continuity with a multi meter it should show Ohms or a closed circuit. To test it when water is overflowing unplug the unit and see if it still overflows or continues to fill. If it stops when unplugged. Then it is not a water inlet problem but an electrical signal problem going to ur water inlet valve. Possibly from the panel or board. the most likely cause is the water valve. What happens is the water valve will stop letting cold water into the washer; therefore, once the washer gets to rinse it will either stop or not do anything during the whole rinse cycle.
This is because when you selected your water temperature, you selected warm/cold or hot/cold. The hot water came in and you didn't notice any problems. When it got to rinse, the cold water the cold water won't come in. Therefore, the washer does nothing.
To check the water valve, first cut the water off and remove the hoses off the back of the washer. Then one at a time point the hoses inside the washer tub and turn the water back on. If you don't have good water pressure, turn the water back off and remove the strainer that should be in one end of the hose. Inspect the strainer to see if it is stopped up, clean it and reinstall it. Now repeat this test. If you have good water pressure now, reinstall hose and your problem is fixed.
If you still don't have good water pressure, the problem is in your house plumbing and you need to call a plumber. If you had good water pressure the first time you performed the test, the water valve is bad and needs replacing.
