have you confirmed the socket you are using has a secure earth connection ?also are the clothes you talk about nylon or cotton. Static is more likley with man made fabrics. Try using tumble dryer sheets as these reduce static and see if it helps

Thanks for the reply – I still think there is a possibility of the drum becoming live .. not a huge probability maybe , but still a possibility. Live wires running at the top of the cabinet , and for beko models with a drum light wires going near the drum there and the heater at the back.
Yep, I think there were some mixed cotton and synthestics. if the dryer had a earth strip at the back of the drum I predict the static would have just discharged down through the earth.
iadom wrote:Perfectly safe, depending on the design an earthing strip is not always needed and I would say that not many manufacturers have actually used that simple strip found on the Creda based dryer. Some types use an electrically conductive belt for instance. If you don’t have the means to do so I suggest you get an electrician to check the wall socket ASAP.
you seem to be more fixated with the earth protection to the tumble dryer rather than the real problem that there is this large area of metal that is not earthed and apart from static electricity issue that it does not appear to be safe if the drum is not earthed on a tumble drier – all I can do is hope for more replies to balance things out a little more
iadom wrote:You need to test the Earth in the wall socket the dryer is plugged into, you can’t do that properly with a simple multi meter.
Regardless – just push that to one side, because the earthing is fine in this house and I am sure the earthing is fine at the socket and onto the dryer cabinet.
Pushing that to one side , have you any view on that they do not fit the earth strap and do you think its safe or not safe that they dont earth the drum on their dryers?iadom wrote:It sounds as though you have an earthing problem on the machine as a whole. Have you checked the condition of the mains socket this machine is plugged into, particularly the earth in the socket. That earthing strip was only fitted to the Creda based Hotpoint dryers, it wasn’t used on previous models and isn’t common on any other makes.
With a continuity tester (multimeter) it beeps when prong is touched to dryer cabinet and earth pin on the 13a plug of the tumble dryer. But no continuity when one prong on earth pin of plug and touched on inside of drum – its exposed metal. I think it should be earthed for safety .
I can see why there isnt earth there because the drum rolls on rubber bearing wheels at the front of the dryer drum and at the rear the bearing is made of plastic it looks like. The spindle on the drum shaft is metal

The list of all the various eeproms for the whole of the Indesit/Hotpoint/Creda/Ariston range runs to several pages. The Hotpoint engineers are supplied with blank eeproms that they can load the required info onto, it should follow that any updates could also be done in the same way.
Unfortunately none of this information or the required hardware is available to the independant trade. 😥
I don’t know the exact figures but I hear that failure within the first few months due to the Indesit type electronics now used in the Hotpoint machines has greatly increased. 😥
With reference to your ‘extensive’ web site, I have one or two comments regarding your suggested improvements. To soundproof the motor is not a good idea, it needs to be allowed to cool iteself and is not a source of major noise. You have to remember that if you had bought a machine to this specification from Hotpoint/Hoover or similar, more than 20 years ago it would have cost you well over £400 then. Fast forward to today and all your improvements will not be implemented for one reason only, cost. you can have all the features you desire today, but as we here are fond of saying, ‘ you only get what you pay for’ buy a higher priced Bosch or Siemens or better still a Miele and you will have a solid, quite, reliable machine.
Thanks for your reply. Points noted about my website I must update the bit about the soundproofing around the motor housing. i didn’t take into account about the ventilation.

I have just dug out the Invoice from the engineer and he has put down 120rpm rotation speed on wool wash on the print-out.
I know there is not much difference from 90rpm to 120rpm but I wonder if this is right to be rotating at this speed (120rpm)
He also put down on the print-out : Advised normal operation as advised by helpdesk.
I lose a bit of confidence when a proper Hotpoint Engineer comes out and has to phone up a help desk to check what speed the drum should rotate at as he said to them: ‘ I haven’t got any paperwork on this kind of machine’. (WF840)

Thank you for the reply. I think there is a big difference between ‘gentle agitation’ and stick to the drum.
Also I cannot understand how we used to see the clothes gently go over the paddles when we used to do a wool wash but now it sticks to the edge of the drum. I am sure we were not dreaming it! 🙂
