You say Red float switch is activating drain pump=water in base How is the water getting into the base? Check if the pressure chamber is gunged up and not stopping the fill from the matrix which could give an overflow Your machine has the aquastop external inlet valve and...

you have a leak and water is collecting in the base and then activating drain pump via the safety float switch. Power off Panels off,kick plate and lower cover plate off will give you some access. Popular places are the front hose between pressure chamber and sump,pressure chamber...

Good luck with the valves....it certainly shouldnt fill on a dry cycle I think it should be just a trickle to condense. If it isnt a valve then it may be wiring to it (again check continuity) Failing that then it could be the control board.

May be worth checking the inlet valves -you may have some cross over on the dry cycle as this uses a cold feed condensation feed I believe. Resistance checks on the valves with the lid off and power off should tell you if the valves are ok

Check the resistances across each pair of motor pin connections. You may have a six,seven or eight pin connector some of which will be common grounds(usually end) There should be three circuit pairs eg 2,3;3,4;5,6 etc One will have a relatively high resistance say 25ohm (main coil) another...

sent you a pm with a link on another forum showing some pics...did you not get it?

If the machine is running "as normal" and you have eliminated blockages/leaks and pump problems then you should check if the machine is heating....or not To help more you should post the full model code and FD numbers located on the door rim

You need to remove the brushes and check for wear. You may have to remove the motor to do this. New brushes are probably 5-6cm long anything less than a 1cm ish There is also an excellent video on this site (somewhere?) re changing brushes on a Bosch by Penguin 45. searching on...

you certainly seem to have been unlucky...it is very hard or probably impossible to track down major spares third party for miele...its an exclusive club more or less... Before you call them out I would for sure check the brushes on the motor. Failing brushes can give all kinds of strange...

The bottom arm is pushed on with a four pronged clip the top arm is held in place with a round knob which pushes through and turns about a quarter turn-i think Diagrams are here https://www.bosch-eshop.com/eshop%28bD1lbiZjPTAwOQ==%29/bosch/gb/prodp.htm?prod=SHU9905UC%2f10&ESHOPTYPE=S

It is relatively easy to remove the matrix and pressure chamber. Please pull out the plug before tackling any of this... Remove lid side panel and front plastic kick plate. Undo both screws securing the metal plate that runs under the door -screws are just beside the door hinges. You dont...

You should post the model number and FD codes on the inside door rim/rear label or sometimes inside the bottom left drain pump cover. If the machine is only 18mths old then Bosch machines are sold with a universal 2 year warranty so I would be calling them for service! I assume you have...

JOB WELL DONE!! Congrats....

will try and help.........my 10p worth Have you checked the circulation motor is working OK? -easily checked by viewing the motor turning at high speed on the RHS of the machine with the panel off. If this isnt working/jammed or leaking then this will cause a backup and activate the...

Can you post model code and Fd number imprinted into inside door rim?

Still a good quality all steel machine-bearings are pretty cheap if you look around less the twenty quid... If you have fitted bearings before then 2nd time around should be easier... You should not need to remove the drum. You remove the pulley, unbolt the bearing cross from the outer...

You will have to remove the matrix and the pressure chamber for cleaning. You will probably have to remove the top plastic corner angles as these are sometimes used to hold corners of the matrix in place. Some also have retaining bars...... With patience all the hoses will pull away from...

good to know you solved the problem! As a matter of interest does anyone know the thermal fuse spec for the Bosch motor....just had one go oc due to PCB failure. Would like to repair the motor but would like to know the temp spec of the thermal fuse if possible......anyone? Thanks in advance

Have you checked the internal fuse for continuity? ie is it open circuit? It is also worth checking the connector block for continuity back to the main PCB -the connector block is not very good imho and a wire can easily come adrift. Worth looking at if the motor appears good with resistances...

Your machine is probably suffering from underfilling and/or poor circulation. You havent given the model number or age but you need to disconnect and pull the machine out. Remove lid,remove left side panel,remove lower kick panel and front cover plate. This will give you access to the matrix...
