Larger brain required.

[megawatt]

Is any one out there who has come across the following.
Hotpoint W100FW works OK, except when the drum should turn ACW it does nothing.CW and spin is OK.Timer replaced but still the same.
I am interested in any brilliant theories

megawatt,

Welcome to the site by the way and enjoy! 😀

You may recall my reply to you via a PM request you made yesterday as follows:

Meanwhile with the Creda W100FW I guess possibly the wiring from Timer to Motor is suspect?

I am sure others will lend a hand with your problem, meanwhile I have ‘moved’ your question appropriately into Trade Technical Enquiries 😉

Re: Larger brain required.

Hi again Martin,
I’m getting there slowly.Thanks for moving me to the correct site.I did not check the wiring as I assumed that any open circuits would loose me all controlled motor action.It is a mystery!?

Re: Larger brain required.

I don’t know this particular machine but the control unit is the same as wm51, wm61 etc. The motor reversing is done solely on the control unit and I would have suspected the timer as well.

It it a GDA motor or a FHP motor?

Does the motor run correctly on the forward tumble with a nice ramp up to spin or does it ‘lurch’ into spin?

If it doesn’t sound right it might have one faulty field coil, this might only show up in reverse tumble. Check that both coils have the same resistance.

I’ll put my thinking cap on as I am sure I’ve had this problem before.

Re: Larger brain required.

Try giving the motor relay on the timer PCB a sharp tap. Can’t be wiring – it’s the same loom for all motor functions.

Hi Bob,
It is an FHP motor and a 904 2440 17 timer.
I did’nt notice anything wrong with the motor action,but I will check that as I check the coil resistance.I’ll keep you posted,thanks for the advice.

Re: Larger brain required.

Nice logic Chris,but I’ve replaced the timer.

Re: Larger brain required.

Probably worth taking the brushes off and checking their length and that one is not sticking in its holder. Also worth tugging gently at motor wiring around plug to look for loose terminal. Maybe prod it with wooden stick to provoke it into action when it’s supposed to be reversing.

Re: Larger brain required.

Mike! What are you like!

Please don’t tell people to prod around in a live machine.

THERE’S NO EXCEPTION….

DON’T WORK ON A LIVE MACHINE !

Re: Larger brain required.

Mikes ‘big stick’ was said a little tongue in cheek I suspect 😆

In fact the expression used so very often by us in the trade is “Poke and Hope?” and that derives from our colleagues in the Browngoods Trade. As they often used plastic/nylon knitting needles to tap valves and soldered tracks for dry joints whilst being plugged into the mains! 😉

I use a 4 foot wooden broom handle to switch Indesits on …EVERY TIME! :rotfl:

Bob.
Don’t tell others how to do their work.Perhaps you take things too seriously. SOMETIMES you have to work on a live machine. I’m still here after 23 years doing this job.

Re: Larger brain required.

Sorry, I dont intend to tell other people how to work. I just don’t think it is a good idea to tell people on a forum such as this to do anything that is dangerous.

Of course there are times when you have to work on a live machine, it’s part of the business, but surely the most important thing is work safely and at a distance.

Re: Larger brain required.

Bob,
I think you are right when on the public forum but as this is the trade forum many things get said for fun but can you look up the part number for me on that wooden stick.
Regards

Re: Larger brain required.

Thanks Martin,Bob,Chris and Mike for your advice.
I am due back tomorrow for round two!
If I do poke it with something,I certainly wont mention it.

Re: Larger brain required.

Appreciate your concern, Bob.
I did vaguely hear something a while back about it being illegal to work on a live machine. Is that true ❓ I suppose this would be aimed at protecting the consumer as much as at protecting the engineer against himself.
Perhaps I do have a tendency to take a few too many risks but I’ve been very lucky so far and have never had a serious electric shock or (touch wood) lost any fingers. So far never had any claims on my PLI either. I think that is because I am sensitive to danger in general, having a strong dislike of pain, so I keep an eye out*.
I think I’m in far more danger from drivers on the road be they insured or not.
(*er, perhaps I should have said “look out”).
I’ll try and restrain my enthusiasm to advise others of my wicked ways a bit from now on and when I go to work tomorrow I’ll imagine you’re there Bob, looking over my shoulder, and I’ll try not to do anything to cause you to gasp in horror.
Mike.
PS There’s only one f in professional.(That’s my moment of pedantry).
