You probably need to remove the hoses at the back of the machine and clean out the screens inside the inlet connections. Just to be sure it's not a piping issue put the hoses you just disconnected into a bucket and turn the vale on to check the pressure. If you have a single lever valve be sure to hang onto both hose as the water will come out of both when you turn the valve on.

Thanks, i also forgot to mention that the new faucet had very low pressure. Which is weird because the spray arm is strong.

What new faucet? is it different than what the washing machine is connected to?

Customer: replied 1 year ago.
the connections for washer are under the sink in the laundry room. This is what i replaced, 3/8 connections for hot and cold lines for faucet, with washer fittings shutoff. I used the shark teeth connectors.

Ok, washing machines typically require a full sized 1/2" supply. So it's possible your supply lines are too small. The inside of a 3/8" OD line is only 1/4" so the volume through that pipe probably isn't enough for what sounds like a fairly new machine that monitors water flow. But try what I suggested. The screens could be clogged with debris that got stirred up when you turned the water back on.

One other thing, the faucet may have low pressure because the aerator at the end of the spout is clogged. Have you tried cleaning it out?
