Washer gw712 diagnostic lights3rd from left and forth from left on and last on right

Linda. I know nothing about this washer, but I did get this info from the attached link, you may still have to call a tech.
Put into diagnostics (left, right, right, right, left, right) @ done you see errors, @ spin you run calibration(this will clear codes and reset board). good luck

Easy to check the pump but you need to have a bucket handy. Tilt washer backward pump will be on the right side. Remove and clean. Watch out for the water!

GWL Washer won't spin only beeps; Diagnostic lighs:the third light is lit up green in the bank of lights on the left; the first light on the right is lit up orange and the third is lit up red. Thanks,Hepi

The two things you need to look at is the screens on the inlet of the washer, thes can get plugged with sediment and block water flow, take the hoses off the machine and look for the screens, either in the hose or water inlet connection. Second is the inlet valve, AI will include a couple of pictures of this. If you have an ohm meter all you have to do is check for continuity across the valve, if there is none the valve is bad and needs replaced.
The control panel lifts off by removing two phillips screws on the back of the control panel. The panel then flips over. The picture below shows what it looks like with the control panel removed The inlet valve is on the left.
Not shown above are Power Control and Pressure Sensing Module, which plugs into the water inlet valve nipple, and the tech sheet, which you'll find folded up to the left of the water inlet valve. The tech sheet gives detailed instructions for entering diagnostic mode and interpreting the binary diagnostic code generated by the LED display on the control panel touch pad. anew inlet will look like this. or very similar, depending on the model.

There is no filter on this model.
You can use a washer cleaner from hardware store.

u need a new cold water valve

There is an issue with your drainage area. Best to remove the pump and check for the obstruction in the line or at the impellar.(If the water is not completely drained, the pressure switch wont send a low level to the timer to allow a spin).
