We are working on a 2 year old ge top load washer that will not pin out at the end of cycles.

We have tried a used pump and board, new lid switch and pressure hose.

All hoses, pressure dome and tub are all clean.

This is the second washer of this style were we have run into this problem without being able to figure it out.

It pumps out the water for aproximately 10 minutes before coding out or spinning.

Error codes 16 and 18 (slow drain) keep on happening.

Hello
Error #16
Fill tub using service mode test 7 and check drain pump operation using service mode test 12.
• Check drain hose for blockages.
* make sure drain hose does not have check valve.
• If pump does not operate, check that the resistance of the pump matches resistance table and verify
120VAC while pump is operating at J512 between the purple and white wires.
• Check pressure tube for pinches where it goes through top cover grommet.
• Use pressure sensor test 10 to ensure correct pressure sensor operation.
• Check pressure tube for trapped water.
• Ensure pressure chamber port is free from obstruction using drill bit size 1/16″ by hand so as not to drill through the inner wall.
