Re: Help needed!
The electronics on these ‘Indesit’ machines are known to be very unreliable.
F04,F05 and F11 all relate to various drain pump faults. Have you checked and if needed cleaned out the drain pump filter?
F01 is more of a problem, it is supposed to be a main motor triac fault but it can be anything from a loose wiring connection to a motor or main circuit board fault.
If it is under five years old then you are covered for all parts and Hotpoint (Whirlpool) will only charge you for the labour which is just above the £100 mark AFAIK.
