Machine will not do the last part of the pump out,does the first 3 short bursts but not the end one that empties it completely so goes to E25.no blockages in pipes.can anyone help on this please.
Any disaster can occur with these Bosch contraptions! Difficult to work on too to add to the head banging experience – only Germany could design these for revenge purposes!.
You`ll have to turn the power off and remove the door panel and the plastic plinth to get at the galvanized panel 2 screws to see/get at the gubbins BUT BEFORE YOU DO ANY OF THAT CHECK 1) AS BELOW FIRST. Based on what you`ve done so far based on “pipeS, so in the plural” so presume you know how to take these things to pieces anyway. Check the simple stuff first. Refering to the Bosch uk online spares site – parts line drawings on the 4th page & I`m refering to the item number not a part number. 1) Check that the drain pump chamber cover is actually properly clipped in; 0434 – that`s the most usual problem. 2)Check the one way non return valve 0431 isn`t blocked up, this is hidden in the sumps pump exit nozzle where the semi transparent pipe joins (that then goes to the fill matrix / pump out matrix unit l/h/s of the machine that area can block up as well), can catch the unwary out, a bugger to get at to, not that common so probably not that. 3)Check the drain pump BUT you have to bail the machine out first- this twists off the sump so you can check for foreign objects, can be a fiddle to refit 0455 &; probably will not be that; DO NOT TEST this with a mains test lead just in case you are tempted! MAKE SURE you sponge any spilt water from off the base from when the pump was removed. 4) Could even be pcboard (hopefully not for your sake and you cannot test it anyhow but you could see if water has not dripped on it – if your tank base – where the filters are – is a plastic base too the plastic tank warps and allows seepage to fall over onto the below pcb fitted rear right – clever it is not!) on page 5 item 0570If you find it is 1) do that and touch nothing else.
