What Does Error F38 Mean?

The Fisher & Paykel washing machine error F38 indicates a potential drain pump failure, often linked to a malfunctioning water level or pressure sensor. This error typically arises when the machine fails to detect an adequate water level during the wash cycle, causing agitation issues and resulting in unusual noises. Common causes include a faulty pressure sensor, misreading of the water level, or a disconnected air tube leading to the sensor.

Common Symptoms:

  • Cycle stops with F38 displayed during agitation or shortly after start
  • Machine may not detect proper water level
  • Agitation may not proceed normally

Possible Causes

  • Pressure sensor / water level sensor fault or misreading (medium)
  • Air tube to pressure sensor disconnected, blocked, or damaged (medium)

How to Fix Error F38

DIY Fix Check and secure pressure sensor air tube

  1. Unplug the washer from power
  2. Locate the pressure sensor air tube (usually a small flexible tube connected to the water level sensor)
  3. Ensure it is securely connected at both ends and free of kinks
  4. Inspect for damage (cracks, splits) and replace the tube if compromised

Technician Only Inspect and test water level pressure sensor and related circuitry

  1. Disconnect power and access internal control panel area
  2. Test pressure sensor with multimeter according to service manual specs
  3. Check continuity and operation of pressure sensor harness and connectors
  4. Replace pressure sensor if found faulty
  5. Verify no blockages or restrictions in the pressure air tube path

Parts needed: pressure sensor (water level sensor), pressure sensor air tube/hose

🛑 When to Call a Pro:
  • If error persists after basic pressure tube check
  • If internal sensor test fails or you are not comfortable opening the machine
