Customer service was here today and told me it's normal...
Huh??? Compare the first video to this one from August last year. No such noise here as the washer distributes! CLICK HERE TO GO TO logixx's LINK | ||

Ha, that's what I thought, too. They'll say it normal now and once the warranty is over.. I have a problem. Well, the repair guy is coming back once more to change the dispenser assy, as I told him that the softener dispenser fills with some water during wash and/or rinse fills, which causes early dispensing of the softener. It's not a lot of water but *just* enough to start the syphoning before the final rinse. Maybe one to two tablespoons but still...
I'll try to make him take of the belt as I talked to other people about his and they said dry belts can be (are?) a problem with these machines. As for warranty: it's still cover until the 20th of May next year. | ||

Noisey Washer The warranty may still cover this problem even if it fails shortly after it expires, be sure your complaint is in writing and their response is also written. Send a registered letter to the company with copies going to the dealer, consumer protection, attorney general etc.
The problem is not likely a dry belt, I suggested that the motor be run without the belt to show whether the motor or main tub bearings is causing the noise. This is very easy to do and I would have the technician that is coming out to fix the softener dispenser do this before you sign off on any service. GOOD Luck. | ||

some folk are just plain nuts
Running the motor without a belt on is one of the WORST things you can do!
NEVER do it. As the motor has no load on it it may well run at infinite speed when on a spin cycle with no drum to slow it down and provide resistance. Electronic they may be but there is always a chance to programmer and motor are geared for some load. We found out at a cost a few years ago whereby I nearly lost my sight from an exploding motor in a Hotpoint machine we ran without a belt attached. The Armature exploded from running at full power sending chunks of metal and ceramic towards my face. Injury may not result but you may not have much of a motor left. Bearing tests can easily be done just by removing the belt if you REALLY need to, although its not needed. Motor bearings can be detected by just removing the belt and turning the armature by hand. If they are rough they will soon let you know. Never run it without the belt connected! | ||

Running The Motor With No belt CANNOT POSSIBLY CAUSE ANY PROBLEM and is a standard and recommended test procedure, having the belt on and turning the empty drum doesn't affect the motor speed one RPM.
I don't know what went wrong with the HP washer you were testing but the motor would have flown apart whether the belt was in place or not. | ||

I too have never seen a motor explode when run without a load, and have seen repair engineers do this to test them. Sounds like the one you had, Rob, had a fault on it. | ||

Inverter (quasi-3ph) motors can only run as fast as the commutation. DC motors (brushed, like my ElectroFrigiWhite) have tachometers on the motor feeding back to the controller.
If motors actually ran away to destruction in the absence of another problem like shorted controller, every time a belt broke a motor would explode and we don't hear that. But you're right, a series DC motor with no load and no closed-loop control can overspeed to destruction. I think it would be a bad idea to design a washer that way, because an empty drum represents almost no load and could easily overspeed. But we've seen bad ideas become washer designs before. | ||
