Hello,
I am a new member here but have been on Vacuumland for quite some time.

I am hoping that one of you will be able to help me with a problem I have with my Bosch washing machine.

It has been making an odd noise for a few weeks and then last week I put a load of bedding in and started to notice a burning smell. I wasn't sure if it was coming from the washer as I had just put the oven on. I went upstairs and after a while my dogs were barking and the electricity had cut off. I went to the kitchen where I was greeted by a stronger burning smell. The washing machine had completed the final rinse as the conditioner wasn't in the dispenser and I assumed the power cut off during the final spin.

I immediately thought it must be the carbon brushes as my Mum's bosch had to have the brushes replaced after a few years and sure enough, when I removed the motor to check them they were completely worn down to the point of the copper wire showing at the end. I purchased new brushes, cleaned the motor and tested the machine. It tripped the electricity as soon as I switched it on and after having the motor out several times and checking everything I could, it was decided to get a new washer and the Bosch went to the garage ready to go to the tip. A new Bosch was ordered from Very online as I get discount there, but it would not arrive until the new year as they were awaiting stock.

After trying to wash clothes in the bath,which was very time consuming and too much like hard work, my partner an I decided to source a Miele machine which could be delivered in a couple of days. I was sad to admit defeat with the Bosch because when I was working on it I was impressed with the build quality and it still looks like new even though it is nearly 7 years old. I understand newer Bosch machines aren't as well built and some aren't made in Germany anymore.

Anyway, I decided to give the Bosch another go and plugged it in in the garage. This time it didn't trip the electrics and everything seemed normal apart from there was no life in the motor. The control panel lit up as it should and the pump switched on at the start of the wash program like it usually does. I researched more on the internet and read that an internal motor fuse may be the culprit. Of course, this part was not available on its own, so it was decided to buy a brand new Bosch motor which was delivered today.

Well I fitted the motor, said a little prayer to the universe and several dead relatives but they weren't listening because it still didn't work. I attempted a spin to start with and although the drum did turn very briefly, it did not ramp up to the full spin. I also put it on rinse and spin and the washer fills as normal, but the drum only turns very infrequently, like it's on a hand wash cycle.

I really don't know what to do next. After spending £130 on a motor I really want to get the Bosch working again and get another few years out of it before having to get a new machine. Please, please, please, is there anyone with any suggestions I can try to get my machine working again. I'm wondering if it is a fault with the control panel, but if it needs a new one I'm not sure I could fit it and the cost of a new panel and motor would have paid for a brand new basic washer.

Sorry for the long winded post. Any suggestions would be gratefully received.

Thanks.


Roger

Additional information

Hello,

I tried the machine again but with the top off and noticed a small green flash coming from the control panel inside. It's nothing dramatic, just a brief flash. This happens just before the motor stops after turning briefly.
It is accompanied by a small click. I don't know if this is normal as I obviously haven't looked closely at this part with the machine running before. I did notice that the control panel felt quite warm in the area near the control knob after the washer cut out for the first time.

It could be just a dry joint on the circuit board. It sounds like the problem might be the direction change relay. The old motor probably started sparking when the brushes were well worn and that will have overheated the motor, causing shorted turns in the armature. The motor then draws extra current and damages the weakest point in its supply circuitry.

Bosch Logixx machines are made in Germany still, and have a direct Magnet motor (basically its brushless so it lasts longer - 10 year Guarantee on Bosch Motor). All Bosch's are built to as good standard as the one you describe a Clasixx Exxpress 1400. My Next machine will be a Bosch due to our new Bosch Oven being extremely well made, and them winning Which awards Continuously.
As for the fault-
I think it could be the way you have re wired the motor to the rest of the machine?
Have you ensured that all the wires you plugged back into the motor are plugged in the correct way, and in correctly? Are the brushes fitted properly?

How can the brushes wear out on a brushless motor? Usually the motor wiring is foolproof, as the multi pin plug will only go in one way. For there to be any movement at all the motor wiring would seem to be correct.

The Bosch Clasixx 1400 Exxpress doesn't have a Brushless Motor - it has a standard motor with Brushes.
Only the new Logixx machines with Eco Silence Drive, plus a hand full of older Boschs (such as the previous 1800 spin Logixx model, and the classic Bosch Hydrosensors) have brushless motor.
Brushless motors will just keep going and going and going as the magnets replace the brushes.
