OK its Sherlock Holmes time - baring in mind that the only parts that are used in the dishwasher that are black are either door seals, seals in the salt cap and top spray bar connection at the rear would you just check those for deterioration and come back to me with your results.
I did - that why I asked you to check the seals and report back.
OK let us just discuss the problem for a moment, there are no mechanical things in the dishwasher that can cause this problem so whatever it is and assuming that the pipes and seals are OK has to have come from outside. How happy are you about taking the base off the dishwasher?
OK if you tip it backwards can you take a picture of the base area, I am particularly interested in the heater and water softener module (left hand side with ceramic beads held within a plastic case.
OK the water softener seems to be clean so we know that the water going in is clear. Have you put a cleaner descaler through the appliance since you started to get this black stuff?
OK - well I guess initially the way forward is to remove the heater assembly and change that, are you happy to do this, its straight forward but before you do do you have any electrical test equipment in the house?
IK I need you to set it to continuity so that when you put the two probes together you get a beep. Do you know what the heater looks like?
OK I am going to send you a 'you tube' video clip of someone changing a straight through dishwasher heater. He holds the heater in his hand as he is talking. You dishwasher is not the same make but it has the same type of heater. If you look under you dishwasher it is quite easy to spot. If you put the meter on to continuity (beep) you will find that you have two wires going into the heater connections and one that goes to the earth on the casing, If you put your beeper across the two terminals - tell me if it beeps?
OK good afternoon - where are you with things?
I sent you a message earlier but it seems to have not reached you - did you manage to empty the water out of the dishwasher and locate the tube heater and test it?
If you take the drain hose out of the drain pipe and put it in a bowl near the base the water should drain out into it.
That is fine just put a towel down to soak up the water from the air break, the water softener is a sealed unit the water wont come out of there if you keep the salt cap on.
