Very intermittently the drain pump will run non stop. When it is acting up I can remove pressure tube from maim CBA and the drain pump will still continue to run. I can also blow into pressure tube and pump still continues to run. The pump works great and drains washer fast, just intermittently it will run nonstop. I did clear pressure dome with 3/32 drill bit, no change. The only error code is long drain.

When you start a drain cycle how long does it take to drain ALL the water from the tub? Normal would be 90 seconds or less.
It drain's tub fast, I would say 90 seconds sounds right. But the drain pump continues to run even though there is no water. Never goes to next cycle. If you allow it to run long enough all indicator lights shut off and pump continues to run. You have to unplug and wait. If you plug it back in too soon pump continues to run.
Thank you Jake. The main control board was the answer. Delay in reply was due to issue being intermittent. At this point I think it's safe to say washer is repaired.
Excellent Richard, glad to hear the new main control board fixed it.(y)

Thanks for the update!
