Hi All,

Type: Hoover 300 H3D 496TE washer dryer

I got an error message "E20". It says to clean the filter. I open the small door at the bottom and rotate the circular door in anti clock wise. I could rotate it only 90 degree. But i can't pull it out. The hand book and the official website doesn't gave more details. This should be a simple thing. But I can't figure out how to open it. Please help me.

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

Hoover 300 H3D 496TE E20 filter would not unscrew due to obstruction

The problem
On a Hoover 300 H3D 496TE washer dryer showing E20, the lower pump filter cap would only turn about 90 degrees anticlockwise and could not be pulled out for cleaning.
Likely cause
A physical obstruction inside was preventing the pump filter from turning fully and being removed. This was suggested in the accepted reply and then confirmed by the original poster after access from the sump hose side.
What fixed it
The obstruction was removed by taking off the main sump hose, which then allowed the filter to be unscrewed and removed. The exact object causing the blockage was not identified in the discussion.
Checks to try
  • E20 error message displayed
  • Bottom access door opened
  • Filter cap turned anticlockwise but only about 90 degrees
  • Obstruction suspected inside the filter/pump area
  • Main sump hose removed to gain access and clear obstruction
Parts or tools mentioned
  • main sump hose

Safety: Take care with residual water when moving or laying the machine down. Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hi. There’s been a few people with this problem. The most likely cause is and obstruction inside stopping it from turning far enough or pulling out. It’s described on this article All about the pump filter

Thank you very much Andy. I turned the washing machine upside down and remove the main sump hose. it allows me to remove the obstruction which prevent the unscrewing.

Thanks again

What was inside? It’s not good to turn washing machine upside down btw! Water can run everywhere. Let it stand 24 hours before plugging it back in. Best way is just to lay it down on its front.

Although if it has water inside don’t lay it down at all.
