Bucket full- will not run
For model number ZD300
Hello Pat, Thank you for the question. This is normally an indication the Main PCB Assembly will need to be replaced. We hope this helps!
Unscrew and detached front and back panels, and inside framework holding the sheet metal to the body, after removing the sheet metal, unscrew the box enclosing the control board, use needle nose pliers to unhook the sensor module from the board and place the new sensor into the spots where the old sensor was connected (thermostat area, humidity Sensor, bucket switch, and control board). Close up the unit and your good to go.
