Re: hotpoint aqualtis weight coil springs
Yeah special tool is needed to remove the springs, not sure if one is available to buy as no part number was supplied. Regardless if it is under 5yrs or over 5yrs the best way to get it repaired is through Hotpoint. Just priced the tub you need and its £242stg.
Electronics as such dont give much trouble on these machines as its the 3phase Arciada boards that are used but I could nearly bet there is a hole on your door seal just beside the door interlock and also the pumps get a bit rattley on these after a few years all of which bumps up the price of the parts you would need.
