Re: IDC75 chugging noise
The top of the pump housing is supposed to prise off and hinge backwards. it can be done with care but often as not the plastic lugs break off. You need to prise it back and try and move the two locking tabs to the side at the same time, then with your third hand……. :rolls:
Then you have to try and split the assembly to get at the pump and float chamber.
The pumps can get noisy, a bit soon for that to be happening but the quality from Indesit has gone off a cliff in the past few years. 😥
