What it means

This is an Ariston (Hotpoint-Ariston) electronic washer code that appears when the drain time runs out and the water level sensor has not registered an empty drum. The machine stops with water trapped inside, and the same number can mean another fault on other brands.

Models covered: Ariston (Hotpoint-Ariston) washing machines on the electronic EVO platform; the code shows on the display or as blinking lights. Older mechanical models do not show codes.

Symptoms4

  • The machine stops before the spin with laundry soaking in water.
  • The door lock light stays on.
  • The pump may run for a long time without the water level dropping.
  • A little water escapes when the filter cover is opened.

Possible causes6

  • Drain pump filter packed with lint, tissue and coins.
  • Drain hose bent after the machine was pushed against the wall.
  • Blocked drain pipe or sink trap.
  • Weak drain pump or broken impeller.
  • Blocked level sensor tube, so it never reads empty.
  • Rare main board fault.

How to diagnose5

  1. Unplug the machine, and let hot wash water cool to avoid burns.
  2. Open the small cover at the bottom front, lay a towel and a flat tray, then use the small drain tube if fitted or open the filter gradually.
  3. Clean all debris from the filter and check the impeller behind it turns.
  4. Pull the machine out a little and follow the drain hose to the outlet.
  5. If the code returns, the technician unplugs the machine and tests the pump and sensor tube.

How to fix5

  1. Clean the filter and close it firmly to prevent leaks.
  2. Re-route the hose and remove the bend.
  3. Clear the drain pipe.
  4. Fit a new drain pump if it is weak or failed.
  5. Clean the sensor tube or replace the sensor, then try a spin-only program.

Frequently asked questions

How often should I clean the pump filter?

There is no single interval for every home; follow the manual, and clean it at once if draining slows or this code appears.

Can the code appear after moving the machine?

Yes. Pushing the machine against the wall can bend the drain hose behind it and stop the water leaving.
