Airconditioner

View all 3 codes →
CodeMeaning
E5E5 means the indoor control board can't talk to the outdoor unit. Either the communication signal on the S or 3 wire dropped out completely, or the outdoor inverter's overcurrent protection tripped. Either way, the two halves of your system aren't syncing anymore, so the whole thing shuts down as a safety measure.
high
NOT-COOLINGThe unit is powered on and the fan is operating, but the refrigeration cycle is not functioning correctly to remove heat from the room. This is typically an airflow or compressor start issue.
high
NOT-COOLINGPower's on and the fan's spinning, but the refrigeration cycle either didn't start or it's running so inefficiently that you're basically just blowing room-temperature air around. The compressor's not engaging, or it's starting but can't maintain pressure.
high

Dehumidifier

View all 6 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.
moderate
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.
moderate
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.
moderate
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.
moderate
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.
low
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.
moderate

Refrigerator

CodeMeaning
BROKEN-SHELFPhysical damage, cracking, or sagging of the door bins or shelves, often caused by weight stress or temperature-related plastic fatigue.
low
E0The control board lost its reading from the ambient temperature thermistor. Basically the sensor that measures your kitchen's air temperature either went open-circuit, short-circuited, or got disconnected, so the board threw this fault to let you know it's running without that data.
moderate
E4E4 means the control board lost a usable signal from the refrigerator compartment evaporator thermistor. It's looking for a resistance value in a specific range, and when it gets a wild reading or nothing at all, it flags the fault and disables normal defrost operation to protect the system.
moderate
MODEL-LOOKUP-HISENSEThis guide helps you locate your Hisense model number sticker and decode the model string so you can pull the correct parts diagram. Without the exact code including the suffix letters, you're basically guessing at what's inside your specific unit.
low
NOT-COOLINGThe fridge isn't holding temperature in the fresh food section, the freezer, or both. Something's blocking heat from escaping the system, preventing refrigerant from cycling properly, or a sensor's lying to the control board about what temperature it actually is in there.
high
TEMP-SETTINGThe temperature control dial tells the compressor how long to run to hit your desired coldness level. On Hisense mini fridges it's a mechanical dial numbered 1 through 7. Higher numbers mean the compressor runs longer and harder. It's not measuring actual degrees, it's controlling cooling power.
moderate
WATER-FILTERThe water filter is a replaceable cartridge designed to remove impurities, odors, and sediment from the water supply before it reaches your dispenser and ice maker.
moderate

Washer

CodeMeaning
F01The F01 code triggers when the washer fails to reach the programmed water level within a specific timeframe, usually 8 minutes. It indicates a slow fill or no fill condition that prevents the cycle from proceeding safely.
moderate
F03F03 means the control board timed out waiting for the tub to empty. The pressure sensor was still reading water present after the pump ran its full drain cycle, so the board shut everything down to protect the motor. Something's blocking the water from getting out.
moderate
F04F04 fires when the control board sees that water temp isn't climbing during a heated cycle, or the NTC thermistor is sending back a reading that makes no sense. Basically the board expects to see temperature rise after it switches the heater on, and when that doesn't happen, it throws the code and stops the cycle.
moderate
