Pull out the washing machine so you can see the hoses. Are the faucets on? Do they allow water to enter? If not, than you have yourself a problem, but you can solve it easily. If hoses are kinked, simply straighten them.
They can be heavily clogged. Unplug the machine, then disconnect the hoses from the back. The filters on the back sit in the water inlet valve. Clean them out.
Water inlet valve
If the filters are clean, you’ll need to check the water inlet valve and the water volume selector switch to ensure it is set properly and that the buttons on the control panel are fully depressed.
Very slow flow
If the water only flows and fills very slowly and both the hoses and the filters are fine, the problem will be in your house’s plumbing.
There are an additional two ground rules to follow: have a washing machine repair man you trust available on short notice, and use a detergent that is not only developed to be applicable with all machines, but cleans outstandingly at the same time: like Ariel Power Gel does.
