I had the water turned off for a day and now the cold water just drips into the washing machine. I took the end off that was connected to the machine because someone told me there was a filter that caught debris when the water came back on, however I didn't see a filter.
Shut off the power to the machine at the circuit breaker, unplug the machine, turn off the valves at the wall, slide the macchine out from te wall far enough, unthread the hose from the machine, put the hose in a bucket, and turn the valve back on. If you get a good supply of water, the problem is in the machine. If not, disconnect the hose from the valve on the wall, and see if you get a good supply of water from the valve. If so, the problem is in the hose, and if not, the problem is in the supply line.
Sometimes the filter is at the end of the hose attached to the wall faucet.
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
