Indesit drum issue

[Penfold72]

I have an indesit IS31VUK unit. I recently had to replace the thermostats due to it not heating up.
Now it’s started to misbehave again. When it turning its OK, but when it pauses to change direction the drum fails to start turning again. All you hear is a hum like it’s trying to turn. Is you try and rotate the drum by hand it’s a little stiff.
If I switch it off and on, it works OK for a while.
Not sure if it’s the belt, and with this unit to get at the belt the whole thing needs stripping out, so don’t want to do that if it’s not the issue.
Anyone any ideas. Could it be motor brushes or something

[electrofix]

its a dryer and they dont have brushes

most likely cause faulty capacitor

seems to show it as a 5uF

https://shop.ukwhitegoods.co.uk/3068008-washing-machine-tumble-dryer-dishwasher-capacitor-5uf

check value before you replace it but the value above seems to be correct

there are other things it can be but capacitor failure means motor starts with small loads but has no power to start larger ones

Yep I agree most likely the capacitor. the Indesit part number is C00109618 and it is listed on the Indesit spares site at a rip off price £33 (rounded up). if you go on ebay uk and type the part number in they are 37 quid under that number. If you type in: 5uf ducati capacitor (which is the brand indesit fit) and it is just over £10.30. This one should be of a higher quality than a £5 jobby. A great deal of the capacitors out there are Chinese and they are not overly brilliant and some are down right awful but any make can fail when it feels like it.

Brill thanks for the replies. I’ll get one of those and see if it fixes.

Would this work. They are close to me

should do

Dave

[electrofix]

probably need a rear shaft kit

drum has to come out as you have to drill out the old rivets

part no c00305794

its not a bad job to do but its common with these rear bearings

as for capacitor are they both 5uF ?

Dave

[Penfold72]

Thanks for the response Dave. I’ve seen the procedure online and it looks involved but not too fiddly. Ill just have to find a rivet gun!!
With regards to the Capacitor, yes both are 5uf, but the valves next to 425v and 475v are completely different to the one that’s in. Will it still be OK to use?
Inclined to fix this one, as I’m loathed to throw anything away, particularly as new they are at least £170 and I can fix this one for way less.
I assume the groove on the new capacitor is equivalent to the raised edge on the old. Does it matter which side the connectors go on as long as I replicate keeping the correct 2 together on the same side? 2 reds one side of groove and 2 browns the other?

[electrofix]

you dont need a rivet gun they give you screws in the kit

just need a drill to drill out old ones the correct size for the screws

capacitor connections dont matter either way round

Dave

[Penfold72]

Ok. Video I looked at on you tube showed my model having a square bearing not a teardrop one. Is the one you mentioned an upgrade to the square one? Just need to ensure get the correct kit. Assume capacitor is ok then?

[electrofix]

if yours is square then there will be 3 screws at the back of the drum dont need drill or rivets

forgot it was the 3Kg model , dont see many of them

Dave

[Penfold72]

Yeah
The video shows 3 screws holding the rear shaft to the drum but rivets attaching the bearing holder to the back of the machine. Kit also comes with rivets??
https://www.ransomspares.co.uk/parts/tumble-dryers/hotpoint/drum-shaft-repair-kit/4853.htm
Or do I just need the rear shaft and use the bearing that’s already there.
Yes.. 3kg dryers are hard to get hold of. Got it as it’s the right size to fit where it is.

[electrofix]

by the look of the pic you will have to rivet the new frame on to hold bearing securely

Halfords do the gun for £10

[Penfold72]

Thanks Dave. Looks like a new skill to learn. Still cheaper than a new machine.
As an aside, will that capacitor be ok as it’s 5uf even though the numbers by the voltages are not the same. I can take back if needed.

[andyjawa]

Now you tell us that the rear bearing is nuked this allows the belt to go slack so maybe you do not need a capacitor after all. I mean, how the hell did you miss this as it would`ve been squeaking for weeks until it lathed through the rear panel.
This is the achillies heel of the whole series. You have a stretch belt pulling 60lbs downwards with no jockey pulley putting pressure on a phosphor bronze bearing that receives no lubrication..so what the devil did Indesit expect to happen apart from the motor bearings also complaining? Poor design and they were told that years ago but did not take any notice and they never did even when I worked for them for 15 years; useless bugg*rs then and now IMO which is why I lost my temper with them in the end – chased a service director around the warehouse with an induction motor to throw at him-biggest mistake I ever made as I missed the blighter – only joking………it was a hammer! No sense of humour some folks!
The original design used a square shaped fibre bearing (obviously with a round hole!!) with a jockey pulley and that worked just dandy, the next incarnation used a phosphor bronze one with no j/pulley but also a variant used the more common infamous teardrop bearing with no pulley too hence mass confusion – typical Indesit so see the kit here, you want: kit part number C00095655. Suggest you go for ebay item number 14439519221 @ £9.70 which is probably the pattern part or go for the genuine at 14 something or other it makes no odds as they are the same kit in anycase repackaged it is just that the genuine comes with a fitting sheet (or did) of instructions.
You will need a pop rivet gun and an electric drill to take the rivet heads off – do not be tempted sticking a flat bladed screwdiver and prising off the bracket as you will just be bending/distorting metal underneath so not clever. It is easy to do just a bit time consuming circ a mere 30 mins.
As modernish t/dryers go the rest of the contraption is reasonable and well worth doing rather than investing in another, heavens forbid a heatpump model of any make…often they`re just a world of hurt you do not want- more energy efficient maybe, simple and inexpensive to repair they ain`t!
