Re: indesit
When you set it to a wash programme does it appear to be making the ‘normal’ noise.
Set it to wash and during the cycle open the door quickly and see if there is a good jet of water coming out of both spray arms.
TBH, we generally advise the use of separate detergent, rinse aid and salt if required. There are lots of problems associated with Indesit machines in particular due to using combination tablets.
Fairy Active Bursts are also a better alternative to tablets.
