Can's say I have seen anything re the Hertz on the display, can only think it may be a later or earlier software version than what machine uses (v106 I think). I would think it would be representitive of the RPM the motors are working at?
I have nothing in my service manuals that mention this, so a new one on me =)
I'm always using the soil type button in diagnostics, takes too long for some parts in the cycle when just checking operation.
Deffo useful for the duvet wash (main reason I wanted one) and it was a good job that it was fixed this weekend, one of the cats decided to chunder on the bed.... ewww! The drum is perfect for this.
The machine was a bargain, an eBay find for £35.00 with F11, the bridge rectifier had failed so that was an easy fix. It started to get louder as the months went by, and it was starting to struggle in contrarotate. I kept putting it off for the amount of time I knew it was going to take, and not being my daily driver wasn't in a rush.
However I am pleased as punch that it's running again, and relativly as quiet as it was. The bearing noise is starting to quieten down. Just need to get the gearbox motor replaced and the rear wheels and the beast can have a full bill of clean health lol. I would estimate by the time I have completed everything it will have cost about £135 in various parts (not just for the drum bearings but other bit's and bobs) but I think well worth it.
