Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today.
Okay I'm going to send you a video on how to replace the chopper assembly which is what you need to replace this but also you need to check how much water is entering the machine at the beginning of the cycle, start the machine and let the water fill and then open the door and tell me how much water is in the bottom in inches ? Does it reach the heater?
Why do you think I have this grity residue inside the machine?
Thanks for the help. I'm pretty sure the heater is working.
I'll switch to gel detergent and run some more Cleaner thru.
