What Does Error F4 Mean?

The Haier washing machine F4 error code signifies a malfunction in the heater or temperature control system, often occurring during the wash cycle when heating should take place. In some top-load models, this error may also indicate a drain timeout issue. Symptoms include the machine stopping mid-cycle or failing to heat water, which can hinder the washing process. Addressing the F4 error typically involves checking the heating element, thermistor, or drain system for faults or blockages.

Common Symptoms:

  • Error appears during wash cycle when heating should occur
  • Machine stops mid‑cycle with F4
  • In some top‑load models, F4 occurs when the machine fails to drain within a set time

Possible Causes

  • Faulty or failed heating element / water heater assembly (medium)
  • Thermistor/temperature sensor fault (medium)
  • Drain timeout on certain top‑load Haier models (low)
