My Wife did a wash last night and when she came down she found the machine with all the lights flashing, I checked the filter and found the pump had a plastic label in it and some grey crude I removed the plastic and cleaned the crude, the machine fill file and the drum turns but I think when it tries to pump the water out I just hear humming noise, could it mean that the drain pump needs replacing?

Solution Summary

AI-generated from this discussion

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

Indesit IWB71250UK stops with lights flashing and drain pump hums

The problem
After a wash, the machine was found with all lights flashing. The filter was checked and a plastic label plus grey debris were removed. The machine then filled and the drum turned, but when it appeared to try to drain there was only a humming noise.
Likely cause
Most strongly supported diagnosis is a drain pump obstruction, with something small still jamming the pump impeller. Pump failure was suggested by the symptom, but not confirmed in the discussion.
What fixed it
Recommended action was to inspect the pump again and rotate the impeller to check whether it was stuck. The discussion did not confirm whether the pump needed replacement or whether cleaning resolved the fault.
Checks to try
  • Filter checked
  • Plastic label removed from pump/filter area
  • Grey debris cleaned out
  • Observed machine fills
  • Observed drum turns
  • Observed humming noise when attempting to pump out
  • Advised to inspect pump impeller and rotate it to ensure it is not stuck

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

There could still be something small jamming the pump impeller. Have a good look inside the pump again, rotate the impeller to make sure it's not stuck.
