Thanks for your views.

Replacing the compressor – not really a DIY job is it?

Yup, pretty hot thanks. I can touch it for maybe 5 seconds.

Does that make it a compressor problem?

Re: Bosch WTL 5400

OK did it.

Here is a step-by-step

Tools , extra long socket arm

Remove top of Dryer (if fitted)
Remove right side panel
Release the spring tensioner – this allows the drive wheels to be tilted back and gives you access to the motor shaft.
Notice that the motor shaft has a flat on it – you will need to put a spanner on the flats in order to remove the two air circulation fans
Remove front air circulation fan – lower right front – extra long socket arm needed here
Disconnect wires from motor
Remove rear panel
Remove rear air circulation fan
Look at the motor close to where the belts are – you will see something that looks like a big handle. It is a big handle, depress the catch and pull the handle. It will come away.
The motor can now be pulled backwards out of the rear of the machine. Pull it out far enough to fit the small belt.
Reverse the process, remembering to fit the belts onto the wheels just before you re-attach the spring tensioner.

Hope thats of use to someone.

Re: Bosch WFK2200GB

Thanks for the advice Martin. I did know that the brushes had a correct way round, and I am certain that I put them in correctly. Thinking about it you have to be pretty thick not to notice the 45degree angle on the business end of the brushes. 😀

I have turned the drum and there is no obvious clicking sound from the motor/comm but … the machine is pushed back into its housing and the back panel is screwed on again, so it is possible that I may have missed a small sound.

If the motor is damaged in some way – (after all something made the circuit breaker on the power side trip) what normally happens to washing machines. New motor, existing motor re-conditioned, machine scrapped ❓

On the basis that the machine is running OK for now, following the £10 investment in brushes, i think I will leave it be. It will either run happily for a while giving more good service, or it will fail again soon and the real problem will manifest itself again.

Re: Bosch WFK2200GB

Thanks for your reply.

I jumped in and did a bit of my own R&D, and found that

Error 4 is indeed drum motor related.
The carbon brushes are fairly worn – 8mm remain

So I went ahead with ordering some new brushes and replacing them. The motor is running again now, but I did not notice any clicking noise. I will go and check for this later when I get home.

The only slightly disturbing thing is a smell which comes from the motor and reminds me of the days I spent playing with Scalextric cars. I am hoping that the smell is one of 2 things. The new carbon brushes bedding in. Or old carbon dust getting burned off. I decided to clean the motor by blowing hard in throgh the various vent holes. (Very scientific I know).

I did the brushes at about 11pm last night, so the machine was not used straight away. But, by the time I get home the machine will have been used and I will have a better idea if things are working.
