Why is the pressure in the line low on my omi DD144 Dehumidifier?

Verify that all valves are open and check the condition of any filters. If air flows continuously through the condensate drainage, clean or replace the drainage solenoid valve. Verify the condensate drainage times set on the electronic control board (C8 and C9). Check the signal from the control board, and if it is continuous, replace the control board.
