The dishdrawer is making an awful noise. On a normal cycle the thing just growls like a coffee grinder 31 minutes before the wash finishes. During the rest of the wash draining is quite, but when the problem occurs it is just this once 31 mins out that the draining begins with this awful noise and then continues quietly to drain. The noise lasts almost 10 seconds. The drawer does drain and the rotor feels fine and spinning freely when removed. There is no blockage between the drain filter and the rotor location.
I did find many metal bits of grit that I removed with a magnet in the bottom of the liver filter. No error codes either.
Help and thanks.

Lincoln, it was as easy as that. I bought a new rotor and had a careful look at the old one which seems to have a metal band or strap under the plastic housing protruding for about a quarter of the rotor housing. It was smooth enough but was bulging out about 1mm. With new,it still is loudest at that 31 minute mark but not like it was.

My next problem is the '>>' button inside top of the drawer. I have dismantled the drawer and looked at it and someone has soldered a ring of solder to the sensor pad possibly to get activation from finger touch. Seems the touch pad is unavailable as a part and you have to buy a complete and very expensive new controller module. It is only the cheap touch circuit board that is faulty, the Eco switch is fine and I know it can skip across all wash cycles. Is there any way of sorting the switch touch plate to work again?

Thanks again.

Thanks Lincoln. That's the thing I didn't know..where else could those bits come from. I feel confused because it only ever happens at the exact same time in the Normal cycle and thought it would do the drain operation several times during the wash. I can interrupt it and it goes away. I just figured a faulty rotor would always play up, and both drawers do it at the same time! Be good if rotors could be rented for testing, but maybe expecting a bit much for that.

Think about it. The sump where the rotor sits is plastic. The rotor is plastic. Only the magnets inside the rotor are metal but you say the plastic coating is still good. Therefor the metal bits cannot of come from the rotor or sump. There is no other moving metal parts. I have advised you what I think the noise is from. If you don't want to buy one, find a neighbour or friend with a dish drawer and borrow one of them for a trial.

Just another note, it will be at the 36 minute mark and then skip the rest to 31 instantly. Not sure if that is relevant.

This time I caught it at the 31 minute mark just as the terrible grinding sound started, pressed the wash button and opened the drawer. It had clear hot water in the tub. Shut the drawer, continued the wash which it did without the grinding sound. All drained quietly. So annoying not knowing why!

They aren't cheap to buy and the ones I have do look good. Why it consistently happens 31mins from the end of cycle but never at any other time of draining is puzzling. I have no idea where the metal gravel came from, not from anything I have put in the wash. Surely a rotor wouldn't deposit metal bits like that!
Thanks for replying Lincoln.

Nothing really to muck around with on those. Suggest you buy one new rotor to start with and see what that sounds like before buying the 2nd one. Also make sure bottom of sump where rotor fits in to is smooth and not been roughed up by any debris.

Unfortunately both drawers do the same thing. The rotors are the newer type and look okay. Don't know what the metal bits are, they look like fine gravel. Previous owner was dodgey so don't know if he has mucked around with the motor pump!
It's a DD60DCX6.

Replace the rotor. If you have a double drawer, swap the rotors over and see if the noise also swaps over to the other drawer to confirm it is the rotor.
