Panasonic Bread Maker

[SemiTech]

Many thanks SDK.

I'd rather pay the extra handling fee and be confident of getting a quality component, rather than take a punt on whatever might turn up if I ordered a capacitor on Amazon.
From the posts earlier in this thread, I'm thinking that this would be the appropriate part - https://cpc.farnell.com/ducati/4-16-10-03-14/capacitor-3uf-450vac-lead/dp/CA05801

Semi,
My pleasure.

Fully understand that as I do also buy from ebay, and items can be defective (eg once received a mains cable that was all protective sheaf with a single strand of copper inside. Above are my 'trusted' suppliers.

The values on you selected cap look accurate and correct.
Also a good brand.

But I have not actually fixed a bread maker (have changed caps on a lot of other equipment inc lawnmowers and DVD players) so cannot confirm shape is correct.
You may need eyeball failed capacitor to confirm shape yourself before purchase.


Edit: I think This is the RS one:

You'd be better off with something with a higher temperature spec, like 105°C...

 

[SemiTech]

Can you recommend one @EightyTwo please, that meets BS EN standards?

For this application I would not bother with a special high temp - 85oC is enough as the circuit should not be getting hot, either from operation or from cooking.

But FYI for the slightly more harsh industrial rated caps I would then be looking at Mouser whose TDKs are rated at 100oC:

But I think they might be B2B sellers.

@EightyTwo, which supplier do you use? Would be good to add to my list.

I like the look of the TDK one, not too big either!

Like many others, I bought mine from Maplin in the early days of this thread! It's still working now (in fact, I have a loaf baking at this very moment!). I had a quick look through some other suppliers but most seem to be 85°C and around a fiver.

Many thanks @EightyTwo

Just to say that I also managed to repair my SD-ZB2502 with the 3µF cap replacement!
Kneads like new, now!
My machine is over 6 years old and has been baking nearly everyday since we bought it (sometimes even twice a day).
The last year, the bread also sometimes didn't seem to rise properly, but not always, until last week 4 loaves faile in a row. I already had replaced the overtemp sensor within the last year, so I feared that I would finally have to buy a new one, until I found this thread (found some similar info on a dutch forum, BTW, but the info here was more clear).
I just hate to have to throw out an otherwise perfectly working machine.
I'll admit that you need a little understanding of how to take apart home appliances and a bit of electronics, but all in all a fairly easy fix!
Thanks a lot, guys!

This is just to day thank you very much for the clue regarding the motor capacitor. (And apologies for being a little late to the party.)

My Panasonic SD-255 had been sat on the worktop for well over a year (probably nearer two) doing nothing after it began not mixing the dough, apparently. I hadn't had much time to look at it but then I caught The Bug and was stuck at home not being able to work. Time to tackle the domestic job list and so I fitted a new drive belt - no difference. Then I found this thread and so I checked the capacitor - less than 1uf. A new part - from RS Components to ensure quality - did the job; very happy.

One thing to note is the solder on the Panasonic circuit board is high temperature so a 25W soldering iron won't touch it (or at least mine wouldn't). My 100W iron did it easily, but you need to be quick to avoid collateral damage.

So, a big thanks to the folks who sussed the problem and posted on here.

I’m almost looking forward to my one breaking!

Good to hear. May I ask which capacitor you replaced and what was the capacity? I took mine apart today and I noticed there are three capacitors, each 0,1uF/300V. Is there another one besides the ones on the main circuit board?

 

[SFK]

You are looking for a capacitor that is separate from the PCB. Coke can shaped, About 5cm in length.

On page 4, there is a photo, and it is the light blue item on the far right.

 

[JonathanK]

Is it covered by a separate piece of the white plastic housing, just above the circuit board? I’m looking at the pictures I took earlier. That would explain why I can only see smaller capacitors.

 

[SFK]

Image on page 4 suggests that it might be.
(I have changed many caps in equipment, but never actually on this bread maker).

It seems the circuit board on the 25xx models is turned 90 degrees anti clockwise, but there is a white plastic bulge a capacitor would fit into. I have ordered a replacement, will post back when it’s done (with pictures).
