I have a Kenmore washer that works very good but recently, when it starts to fill back up for the rinse cycle the water just trickles in taking a long time to fill. At one point I was able to turn on the faucet (on high) in the deep sink next to the washer and eventually the water flow in the washer would return to normal but now, this doesn’t help and it takes a long time for water to fill the drum.
Turn off the water supply to the washer. Remove hoses from back of washing machine. Look into the inlets. There should be a screen inside of the inlet, and it is probably clogged. Clean it out. Replace hoses. Turn on water. Proceed with the washin'.
