BEKO manufacturer not earthing their Drums on their Tumble Dryers

[electrofix]

that why i have a miele appliance much better build quality and the element power goes through a seperate relay not though a cheap door switch etc

as for you earth strap all you need is a piece of phosphor bronze strip or wire and make your own

or use fabric conditioner which is anti static

Thanks Dave – i can most probably knock up a strip of metal. Do you know if it would have to be brass or would something else do? if i were making something in the picture?(I think that was off a Hotpoint dryer)
A bit off with static dryer sheets after reading in the past they leave a ‘film’ inside the dryer on parts. I think I even read once that a dryer sheet got sucked into the dryer or vent hose and caused a fire in a house. Plus the dryer has a sensor and i think I read dryer sheet can leave a film on the sensor and then sensor needs cleaning , and believe me they have put the drum sensor in a stupid place in this new Beko dryer now , underneath the fluff / lint filter – really hard to get to, to clean – at least on the old Beko’s it was in the drum at the bottom on 2 strips of metal which was easy to keep clean.

Yeah , we use lenor fabric conditioner .. is there a special one for anti static is there on the market?

Meant to have said I have come across when I have fixed old dryers that the earthing straps used to have a carbon piece on a ‘springy’ tip that touched the drum shaft, but I dont suppose you can get them these days can you still?

That wasn’t an earthing strip, it was a conductive connector used to sense the dampness in autosense dryers.;)

agree

zanussi drums had that. in fact the rear and the front of the drum were electrically seperate and could not be earthed otherwise the sensor would not function
you can see the rear carbon in this pic

Number 584A is a carbon brush for earthing purposes isnt it?

even those cheap white night tumble dryers have earthing strap on them

[iadom]

The carbon brush is NOT an earthing device. On electronically controlled SENSOR dryers a small current is fed into the drum and is monitored by the electronics. As the clothes dry their electrical resistance increases. This is fed into the electronic controls via the carbon brush to allow the dryer to switch off when the clothes are dry .

Get yourself one of these, a small price to pay to keep yourself safe.

ah right thanks – I was just going by this diagram from here which said 584a was an ‘Electric Brush Earth Carbon‘

to be honest your both right
the rear carbon brush does connect ot earth but the front and rear of the drum is electrically isolated so the second carbon brush running on the front section (item 184) is the sensing wire from the module
what this means from our previous conversation is the front part of the drum has no solid earth connection only a sense wire to the pcb and athough this will stop static it will in no way protect anyone should the drum become live
so even in this case the manufacturer so no need to earth the drum
