zanussi fls 1183w

[fasetester]

went to repair a zanussi washing machine model fls 1183w needed new set of brushes. after fitting new brushes connected up machine to test.

machine would start to fill then bring in the pump. after about 15 sec stop and timer would rotate the whole program would be speeded up. then come to the end of the program would the brushes burning out have

damaged the control card checked the connections at the timer thanks fasetester 😕

Probably just a tacho connection problem you have there fase? Were the brushes stuffed then? As the symptoms you describe are usually as a result of a motor connection problem and NOT a module problem. 😉

thanks martin for the reply checked connections at motor. do you mean a broken wire at connector block at the motor. or broken wire going to taco or a loose taco magnet . fasetester

Re: zanussi fls 1183w

any zanussi engineers care to comment on this problum before i replaced the bruses. when testing on a wash program the machine filled up then when the motor would start to wash. you could here the timer click .

as if the motor signal was ok. no timer spin checked on spin program same as above. brought in water on final rinse pump kicked in but no spin program working.

then after replacing the motor brushes the problum started i think it is a cesnet motor thanks fasetester. 🙂

I was referring to the possibility of the tacho magnet not in place or that the tacho coil was maybe open circuit?

You’ve already changed the brushes, so if the magnet and coil are OK and you have continuity throughout the motor then the connection to it may also be suspect?

The point is that if originally the problem was just that the brushes had worn out and since you’ve changed the brushes the problem has occurred then the problem has got to be associated with the motor rather than the timer…..is my take on it anyway? 😉

Would be checking motor & everything else for earth leakage, those motors seem prone to it i have found.

Re: zanussi fls 1183w

thanks martin for your reply reading some of the other posts. the motor most likely to give problums with taco is the zensole. is the most likely problum with the taco when it does not feed the infomation back from the motor the motor speeds up.

but then on some machines the module shuts the motor down when the fault is found does the machine just start as normal. or does any thing have to be reset to tell the module that the motor is back in action. thanks fasetester 🙂

Yes! fasetester thanks martin.

Re: zanussi fls 1183w

the problum when first told was machine was not empying clothes wet. but after fitting the brushes. the lady of the house then told me she thought it was going throught the program very quickly so the program problum was already their.fasetester

going a bit of track when checking for low insulation. with a megger does any engineer say from a plug top ect. disconnect the module as the megger can damage the electronics fasetester 🙂

Re: zanussi fls 1183w

It’s OK to do a 500 volt insulation test at the plug as that’s what you do when PAT testing a washing machine. For diagnosis purposes you are better disconnecting individual parts such as the motor and heater and using your megger on the particular part.

It should not damage the electronics as long as you are careful to make sure that both live and neutral on plug are firmly connected together to one side of the 500v. If you were to accidentally put 500v dc between say neutral only and earth you could easily damage a module. (Could Tony come on and confirm that?). (Perhaps if I type EMW here, his ears will burn 😆 ).

thanks mike for your reply what kind of reading would you be looking for between the shorted live and netural and earth 1megohm fasetester 🙂

Just to clarify here for you fase. For quick Megger testing of an appliance first check the earth pin on the plug to a suitable grounding point on the appliance. The maximum acceptable reading there should be 1 ohm. Having established that the appliance is suitably grounded then bond the live and neutral pins of the plugtop together. The other on the earth pin and switch the appliance on. The reading on the megohm scale, should be no less the 1 megohm. (Acceptable limit as per 17th edition standards)

I personally would be less that satisfied though at such a high reading and would need to investigate further. In my book less than 5 megohms tells me something ain’t right and would get the tools and and see.

Have you reached a conclusion on this job yet I wonder? 🙂
