Re: HOTPOINT AQUARIUS ( 2000 ? )
Sounds more like a drum support failure, common fault if you use to much detergent and only do low temp washes. If you have stopped using the machine at once then this is a perfectly viable repair, the drum support kit includes new bearings. If you have used the machine once or twice after hearing the noise, you may have damaged the heater.
This applies to WM machines only, if it is a WMA and under five years old then Hotpoint/Indesit is your best course of action.
