Re: how to fix a belt back
The belt used on most of the recent Indesit machines are like most machines of today, ‘stretchy belts’ that is to say the belt is not adjustable but relies on its elasticity to remain in situ. It is not uncommon for these belts to come adrift on Indesit machines. Refitting will be a temporary cure, a new belt is your best option.
Also make sure the drum revolves smoothly, small socks or similar jammed in the drum can throw the belt off.
Remove plug at all times.
