What Does Error EH Mean?

The TCL dehumidifier EH error indicates a malfunction in the humidity sensor, often resulting in erratic display readings or ineffective humidity removal. This may be due to a faulty humidity sensor or misalignment of the water collection bucket, which can trigger a sensor fault. When this error appears, the unit may fail to operate normally, showing 'EH' instead of the standard humidity reading.

Common Symptoms:

  • Display shows 'EH' and unit may not run normally
  • Unit may show EH instead of normal humidity reading
  • Machine may not remove humidity effectively when code appears

Possible Causes

  • Faulty humidity sensor (medium)
  • Water bucket misalignment or sensor switch not engaged (low)

How to Fix Error EH

DIY Fix Basic checks and reset

  1. Unplug the dehumidifier and wait 5 minutes, then plug it back in to reset the control.
  2. Ensure the water collection bucket is seated properly and fully engaged with the sensor switch.
  3. Verify the ambient temperature is within normal operating range (avoid very low temperatures where sensors may misread).

Technician Only Diagnose and replace humidity sensor

  1. Disassemble the dehumidifier casing following service manual procedures.
  2. Locate the humidity sensor (often clipped near the evaporator coils or mounted inside).
  3. Measure the sensor output/continuity to confirm failure.
  4. Replace the humidity sensor with an OEM-compatible part and reassemble.

Parts needed: Humidity sensor module

🛑 When to Call a Pro:
  • If the error persists after basic checks and sensor replacement attempt
  • If internal disassembly is required and you are not trained or equipped
  • If other error codes or symptoms appear indicating broader system faults
