Indesit Difp 28t9 dishwasher Excessive noise

Dishwasher is 2 months old. It is very quiet however it has developed a terrible noise at part of the cycle. I have cleaned the filter, checked the arms turn and it fills and empties fine. How do I go about checking what it could be?

I will try and help with this problem Indesit Difp 28t9 dishwasher

This is very hard for me to identify as I’m not in front of the Dishwasher and I cannot hear where the noise is coming from but you may have something loose in the pump or on the main distribution motor which circulates the water around a machine, if any piece of food has got past the filter or even a small piece of glass or fragments of china then this would make a noise on the motor whether it is the pump all the distribution motor I have put a couple of videos below to assist you but as you did not include your model number I cannot be more help
