6 error codes

CodeMeaning
DRAIN-PUMPThe pump button triggers the control board to activate the condensate pump motor once the internal reservoir hits a set water level. When you press it, you're basically telling the board to stop waiting for you to empty the bucket and just push the water out automatically through the drain hose instead.

E1The E1 code fires when the main board loses its humidity reading completely. The hygrostat, that little sensor board near the evaporator coils, either stopped talking to the control board or is sending back garbage data. No reliable reading means no way to control the cycle, so the unit shuts itself down.
moderateintermediate
E2E2 means the control board lost communication with the ambient temperature sensor, the one measuring the air coming into the unit from the room. The board got either an open circuit (infinite resistance) or a short (zero ohms), and it won't run the compressor without a valid temp reading.
moderateintermediate
E9E9 on a Hisense dehumidifier means the room temperature sensor (thermistor) has failed or is reading outside its expected range. The board's constantly polling that sensor to decide how hard to run the compressor. When it gets garbage data or no signal at all, it shuts everything down.

MODEL-LOOKUP-HISENSEThis guide helps you track down the model number on your Hisense dehumidifier so you can pull up the correct parts diagram. Without the exact model, you're guessing on parts that might look right but won't fit or won't work with your specific control board generation.

NOT-COLLECTING-WATERThe unit is powered on and the fan is blowing, but the refrigeration cycle is not extracting moisture from the air, resulting in an empty water bucket.
