Well via partmaster your model number does not match up with the switch you have by X referencing BUT that could still be wrong.. I think this brick coloured swt is the wrong one ( looks like a Vestel one to me ) or it could be, on the other hand, a replacement one because the old one is deemed obsolete BUT the photo when you type the part number in comes up looking like the oval p/swt you have fitted so it might be right. This is typical battle with Chinese stuff – importers so keen for sales spares end up a bloody mess with no one sure about anything! Did you check the motor brushes?

[andyjawa]

Rechecked elsewhere looks as though you can still get the oval swt under the part number 0024000144 so God knows what this brick coloured swt is, maybe a p/swt in the right packet with the wrong p/swt inside and that p/swt you have looks very much like your typical Vestel p/swt even from the rear and yes the packet is written in Chinese. Do not know for sure beware!

Can I just ask you one simple question. Does the main motor actually via the belt turn the drum? Does the drum tumble one way then another and does the motor make the drum actually spin? yes or no. Does the machine fill with water and stop filling up and then does the drum go around? yes or no. Did you actually check the motor brushes as in removing them off the motor so to visually check the length of carbon? yes or no.

[Mister Linnet]

After fitting the new switch the machine was set to rinse to see if the switch cured the problem, the pump emptied the water but continued to operate on and off until it timed out with Err2.

The machine was then set to eco wash. The machine filled with water and the drum would turn anti clockwise before stopping and then turning clockwise. It appears everything works “ok” until it get to the spin cycle.

So to answer your questions :-

Does the main motor actually via the belt turn the drum? Yes.
Does the drum tumble one way then another and does the motor make the drum spin? It tumbles but doesn`t appear to spin.
Does the machine fill with water and stop filling up and then does the drum go round? Yes
Haven`t touched the motor yet or inspected the brushes.

Hope this helps 😉

does sound like the main board cant see when its empty

if you just try a spin what happens ?

Dave

[Mister Linnet]

Hi Dave,

The machine was placed on setting for spin as per photo #26 after fitting the switch, the pump will continue to operate on and off until the machine timed out and popped up with the Err2 code

[electrofix]

all you can do now is check the wiriing going to the board from the pressure sw. chacking fo bad connections. After that is sounds like the board is faulty

as a very very long shot. Disconnect the wash heater, both cables and see if it makes any difference

unless you can cure the current fault then dont replace anything on a whimm

Dave

[Mister Linnet]

Thank you Dave, as mentioned I will check the wiring as you suggest, that will be tomorrow when I next pop to see my daughter. If there are no issues to report or anything obvious I will have to assume its the main board.

Are main boards worth replacing or usually beyond economical repair ?

[electrofix]

board could well be £100 or so
at those sort of costs you have to balance the fact

1 it may not fix it
2 a new machine would give you a warranty

Dave

[Mister Linnet]

Many thanks again Dave for your reply.

I think considering the age and condition of the machine ( assuming I can`t find any obvious wiring issues ) it will be time to purchase a replacement. In theory I could spend £100 on a replacement main board for the machine, hopefully curing the problem only for something else to fail a few weeks later. That £100 could go towards a new machine complete with warranty…….and save Dad the hassle of trying to repair a secondhand machine 😉

Appreciate your help and assistance over the last couple of weeks

[electrofix]

no problem

Dave

[andyjawa]

did you have a look at the motor`s wiring loom connector block? Looking at the motor shield you might have a corroded terminal wire and as I mentioned the brushes often wear inconsistantly so you sometimes do not get the usual commutator matt colouration as you appear not to have. Still worth a final look, a miniscule amount of effort to be sure..

[andyjawa]

From memory. Have a look at brushes indesit C00196539 and its pattern part equiv car73 ( ignore that the holder/plastic pieces that just happen to be brick coloured that does not matter ).What you want to check is that the angle of the running face points the same way i.e. left or right as viewed the way the brush is fitted and that the teminal ends for the brushes wires are the same size. The Indesit ones are angled to the right.
