I have Hoover washing machine. During my last wash cycle it suddenly stopped washing and gave me E03 error code.
The E03 error code on your Hoover washing machine means that the drum isn't draining - normally this is caused by a blockage, and it only takes a few minutes to fix
What I did later was completely clean the drain filter. (It was already clean when I pulled it out). One thing to mention that when I pulled out the hose to drain the water, it looked like limescale came out as well with the water.
So after the cleaning, I've put everything back together but the problem persists. You can check the video here on how it sounds when I put the drain mode:
Any clues on what else I could try?
