    thanks for your reply,motor has no burnt odour at all and the commutator was very clean,I polished the surface with 400,s wet & dry made sure all gaps were clear.
    The machine has relays clicking but no action from the motor 99% but sometimes it will make as if to start momenteraly. Just once the motor ran normally but not since.
    I am trying spin settings 5 & 8 the pump runs to empty and I can find no restrictions in the pipes

    best regards

He means you would see considerable burning on the commutators where the brushes rub Or burnt windings on the motor.Usually changing of the brushes will fix it .Hope this helps Cheers.

    You can check the relays with a 9 volt battery on the coil of the relay and your meter on the switch contacts(ohmsx1).They may be burn,t away because of the current drain .Also check the field winds for continuity.Hope this helps.

I bought a pride wrangler mobility scooter. Did not move could hear a click coming from left motor. took right motor off and tore it down. It was all glazed over.

If two 24v batteries are the standard fitment it isn't likely it would be fitted with a 36v motor - unless some bright person fitted the wrong one...

I am not sure what you mean by "glazed over" unless it is the commutator you refer to? A commutator made from quality materials and fitted with brushes made from the correct grade of carbon or copper/carbon and being run at approx. the correct voltage is likely to become well polished and may become carbon black in colour but that is without detriment.
It is permissible to clean the commutator. I find spinning the armature in a drill and using a fine emery cloth is adequate.

Once reassembled the motor can be connected directly to 24 volts for testing.

Washing machine motor issues with brushes and carbon dust read this if your...

due to carbon dust build up around the drum motor in most washers that have non linear motor that have carbon brushes
you can get a state of error i call a ghost error
as its just due to the build up of carbon powder around the motor its connector and stator coils {speed pickup}
as the brushes deplete you end up with a pile of it building up between the brush contact and the motor housing leading to electricity leaking to earth of the motor metals

so a stiff dry new paint brush and give the motor a good brush around to remove the conduction path the dust creates

this effects the low voltage sensors in the motor like its speed control etc
leading to the mcu controller board miss diag the motor as bad and you get a E or F motor error
also this can and will trip your homes MCB detector and ECLD mains power switch

as i say its a ghost error and easily solved

any engineer worth his salt when fitting new brushes or even looking at this fault
will do this first to try to clear the fault if the brushes are aok
before he condems the controller board ... as bad

a new set of brushes should be part of a service you should carry out
much like an mot when its outside its warrenty period

and brushing out the old dust
should be done anyway when new brushes are fitted when needed
or there condition checked as still ok

basically brushes should be about at least 3/4 " long for a life left of about a year
and have enough preasure on the armature to ensure good current flow too it via the stator
if you have motor F or E fault conditions or a machine that trips your mains on spin etc
this prob needs done anyway
a set of brushes it cheep and a brush is also cheep

so give it a good brush out
then reset the machine
you power off at the mains
you hold in a button or two
you power on at the mains
ive read some machine need the program switch to be placed and then dialed like a safe to reset the main board from some types of motor fault
caused by carbon dust build up typical candy auto washers.. and others
they make it hard to make people money

Error E30 flashing on washing machine

What brand. Ih it is a hotpoint. I found this on the net from a washer help site in the uk

Error 30 (on Hotpoint) just means the motor isn't working. Several things, including the power module, can cause this. The most common cause though is worn carbon brushes. There is also a 7.5 amp fuse on or near the power module, which can blow. This fuse is on the motor circuit to protect the circuitry of the power module. If it blows, then the motor won't work and you will get error 30.

If it has blown, it's likely to be caused by the motor. I had one last week where the armature in the motor had shorted to earth which blew the 7.5 Amp fuse.

To check the brushes, with the machine unplugged! Have a look at my Hotpoint and Creda carbon brushes diagnostics You can also Buy Hotpoint & Creda carbon brushes

Mercedes heater blower motor e220 comes on and off when it likes and will not select speeds

Check that the fuse is not loose but I suspect that the carbon brushes on the motor have worn or more likely have become ineffective. You may also notice that the fan engages when you turn in one direction but disengages again when you turn in the other. The motor moves slightly on its bearings due to weight transfer and the armature touches the corresponding brushes. You will need to get the motor out to overhaul it and this often means removing the windscreen wiper motor assembly first. The kitchen table on plenty of newspaper is great place to over-haul electric motors; the paper is to keep the mess down and the wife happy. With the motor out strip out the brushes. If they look to have plenty of carbon on them (5mm+) check out the pressure springs that press them to the motor armature. Carbon black and oxide build up can often render the springs action useless causing the the brushes to become fixed in their galleries. Clean everything, armature facings and brush galleries, with an old tooth brush or some such (my wife's old mascara brush works a treat) and lubricate with a squirt of WD40. With everything clean and lubricated reassemble the motor and it should run like new and for a long time.

My wasmachine (asko 10625) doesn't spin at all Not

either motor winding is failed or motor brushes or no power to motor. needs to be tested with a multimeter

1 Answer

Asko 10625 will not spin

it is probably the belt, take off the back of the machine and look at the black rubber belt that spins the cleaning drum. The belts break after about 5 years, you can get a replacement belt at you local Asko dealer, I recall that is was pretty easy to change, like doing a bike chain, Talk to you Asko dealer about how to change it.

I am a technician for Asko in Australia.The blackness on the motor control unit(circuit board) is probably carbon dust from the carbon brushes in electric motor.Likely problem is motor brushes have totally worn the armiture in motor or the MCU needs replacing due to earth leakage or short.Purchasing the parts from Asko should be no problem, but if you purchase and install electrical componenents only to find problem unresolved, you can't return installed parts for a refund. Also the breather hose from the detergent dispensor to outer tank can leak from tank connection when spinning load , and result in water running down outer tank and onto the electric motor causing circuit breaker to trip.....possibly damaging motor too. Goodluck!!

Asko 12003 washing machine- just replaced brushes as it was not spinining well (growling) They were well worn. I ahve fitted the new ones,washed well but was slow spinning and then began to smell. I have...

if you've replace the brushes, and smells... are you sure you got the correct brushes. If too close, especially if there were already some bad windings... could have physically caught some. Burning smell very bad in DC motor. The internal windings could be melting, which means the end of that motor. I would either look for another motor if you're so inclined... or new washer time. However in looking at the model you reference, it would seem you got a very good run out of that unit. If you can afford it, it might be time to say goodbye to the old friend and move on. Sorry, I hope I'm wrong! Good luck

Do I need to do anything special when replacing the brushes in a lamb ametek 117500 motor? It looks like I can just remove the old brushes and insert the new ones. Is it this simple? Will the motor work again? Thanks

I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Make sure they are the right carbon brushes for your particular lamb motor and once you have installed the new ones then there is a seating chalk that you place against the armature to help seat the carbon brushes, you can pick up the seating chalk @ your local vacuum cleaner store or contact Lamb / Ametek listed below. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.
