WAE26470AU-01

Hi All,

My wife reported that the Bosch Maxx Lifestyle (7kg, 1300rpm, WAE26470AU-01) washing machine made a noise reminiscent of a “pop” today and simultaneously tripped all the RCD’s while near the end of a 1300rpm spin cycle.

When I got home, I carefully reconnected the device. All was well until I tried to initiate a spin cycle and the rcd’s tripped once more. Figuring it was the motor, I disconnected it and found that the washing machine was then electrically stable, with the pump activating as would be expected during a spin cycle despite the drum being stationary.

I think the motor is the most likely candidate, but I found that the resistance across the contacts was fairly typical at 1.5-2.0 ohms while turning the motor slowly and increased to 150-200 ohms while turning the motor as fast as possible by hand (by turning the drum). This makes me think the motor is okay; though at 5 years, I have heard that this model will need new brushes.

Here’s some pictures (https://docs.google.com/open?id=0B6B7tNvk7SrVV1ZzMkxqUF9RY3FsV25mZFVsVGVadw). All advice appreciated. Should need be, further tests can be performed with relative ease. I have a reasonable multimeter at my disposal.

I may be jumping the gun, but any recommendation on replacement part numbers and such are appreicated. I’m in Australia, which may be a factor.

Thanks in advance for your time.

Kind regards,

brigman

95{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of the time you only need replace the carbon brushes to cure. Though when brushes finally give up the ghost they can damage the armature’s commutator segments (which will need careful inspection and cleaning no doubt while you at it) 😉

I would presume that the replacement brushes are Bosch Brushes, although the pop your wife heared was proberbly a short being created and you will be lucky if you get away with replacing the brushes and not the full motor.

Hi

If you go for the brushes as Martin suggests and you can’t find any locally in Oz they are available here in our shop for your machine the Bosch part number is 154740.

You may need to enquire with Dave on the postage at spares@ukwhitegoods.co.uk before ordering.

HTH 🙂

Moved you to your own Oz forum. 😉

THIS post suggests that you may well save yourself a large amount of money if you can source these brushes in the UK.
At the time that post was live I checked on a few sites in Australia for carbon brushes and found some unbelievable prices.

Standard Hotpoint carbons 1600474’s, less than £10 all in from this sites shop, were on sale for around £100 sterling. :eeek:

Looks like Qualtex have realised there is money to be made in Oz, still over $80 AUD for non genuine Bosch brushes though, more than 10 times the UK price. :rolls:

What an overwhelming response, thanks guys, I really appreciate it. It’s people like yourselves that make the UK a great place.

I’ll inspect the carbon brushes this evening to determine their state of wear.

Yes, many, many things are ridiculously expensive in Australia, bread, milk, fruit, vegetables, meat, fish, eggs to say the least. Anyone in Australia under any illusions about this should visit http://www.tesco.co.uk and price up their weekly shopping from the UK. If you only pay double what it costs in the UK, you are doing okay.

Hi All,

I have inspected the carbon brushes and they are worn as predicted; to the point that the copper wire suspended within was making direct contact with the commutator.

I was surprised to find that the resistance between different pick-ups/windings on the commutator was, in every case, under 3 ohms. I must be missing something as I expected them to be electrically independent. Any advice in this regard appreciated.

Kind regards,

brigman
