Hi I have the same dishwasher. Yes the user manual says too much inlet water ?! Which is completely unhelpful. Anyway, left it for two weeks (whilst on holiday ) and on return the error code had gone and it worked fine. However, has just happened again and this time I have found water on the floor under the dishwasher, so in fact the servivce engineer answer is correct. There is a leak detection switch to shut the dishwater down in the event of a leak, to prevent your kitchen flooding ! Now all you have to do ios work out wheer the water is coming from !
