Water is coming out of the bottom during the rinse cycle Do I need certified repairman or could I fix it?

Check recirculating pump at back of machine , it might need replacing if it is making noise

WASHER WILL NOT RINSE:
If your washer doesn't go through the washer rinse cycle, 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.
TIMER
If your washer doesn't go through the washer rinse cycle the timer may be the problem. Sometimes the timer gets stuck in the middle of the cycle or won't turn at all. If the washer runs, but the timer doesn't turn, the timer is bad and needs replacing.
Do you have anti-flood hoses leading to the machine. If you do there is probably a loose tube in the back causing a small leak. When the hoses detect that water is still flowing after a certain amount of time due to the leak it shuts down and causes the machine to turn off during the rinse/spin cycle

Go to repairclinic.com and have model number ready. They have videos how to check it

Check the rinse pump. The tubing needs to come from the supply into the bottom of the pump, and the pump should be running clockwise. If the pump tube is worn, the rinse pressure will blow through the pump filling the bottle

In the rinse cycle it will use cold only to rinse with.
You need to see how fast the water is going into the machine on rinse
Things that can effect slow fill, low water pressure, Faulty cold valve
water hose & valve filters clogged, Kinked hose

Take the cover off the back, and look up, next to where you put the soap in, when it's filling/rinsing. There is (like) a (white) plastic valve body, and look to see if water is dripping out of it. I haven't figured out a solution to that yet, other than to replace it.

Also check the boot, coming off the pump. You could have a bad/dry boot, or a loose hose clamp.

most new washers have cold water only rinse and spray rinse ck cold water coming into machine during wash if no cold comes in suspect cold side of fill vale not opening ..could be wiring issue or a bad valve

check the pump it could be stuck
