The F05 error on your Indesit Washing means the machine has detected a problem with the water drainage system, usually because the drain pump isn’t emptying the water fast enough or at all. Fix hint: in most cases this is caused by a blocked pump filter or drain hose, which you can check and clear yourself in under half an hour.

Error code F05
Meaning Drain pump fault — water is not being pumped out within the expected time
Severity Medium — the machine won’t complete a cycle until this is fixed
Time to fix 15–40 minutes
Tools needed Towels, a shallow container, screwdriver (occasionally)

What the F05 error means

Indesit washing machines use a pressure sensor to check that water has drained away properly after a wash or rinse cycle. If the sensor still detects water in the drum after the drain pump has run for the expected time, the control board triggers the F05 error and stops the cycle. This is similar in principle to the Indesit Washing F04 Error Code: Causes and Fixes, but F05 relates specifically to drainage rather than water level sensing.

The most common cause is a physical blockage somewhere in the drainage path — often something small like a coin, button, or hair clip caught in the pump filter.

Common causes

  • Blocked or clogged drain pump filter
  • Kinked, blocked, or badly positioned drain hose
  • Foreign objects (coins, buttons, hair grips) stuck in the pump
  • Faulty or worn drain pump motor
  • Blocked external drain or standpipe
  • Faulty pressure sensor sending incorrect readings to the control board

How to fix the F05 error

  1. Turn off and unplug the machine — Always disconnect power before accessing any internal parts to avoid electric shock.
  2. Check the drain hose — Look for kinks, tight bends, or blockages along its length, and make sure it isn’t pushed too far into the standpipe, which can cause siphoning issues.
  3. Clean the pump filter — Locate the small access panel at the bottom front of the machine, place towels down to catch water, and unscrew the filter cap slowly to remove debris, coins, or fluff.
  4. Inspect the pump for obstructions — With the filter removed, check if the pump impeller spins freely; if it’s jammed, carefully remove any trapped items.
  5. Test a short cycle — Run a quick rinse and spin cycle to confirm the water drains properly and the error doesn’t reappear.
  6. Call an engineer if the fault persists — If the pump motor has failed or the pressure sensor is faulty, these require testing with a multimeter and likely replacement by a qualified technician.

FAQ

Can I fix the F05 error myself?
Yes, in most cases. Clearing the pump filter and checking the drain hose resolves the issue without needing a repair technician.

Is it safe to open the pump filter if there’s water in the drum?
Yes, but do it slowly with towels and a shallow container ready, as water will drain out as soon as the cap is loosened.

How is F05 different from F02 or F03?
F05 relates to drainage timing, while Indesit Washing F02 Error Code: Causes and Fixes and Indesit Washing F03 Error Code: Causes and Fixes cover motor and temperature sensor faults respectively — each points to a different part of the wash system.
