OK lets see if we can make some progress here - I'm not surprised that KnowHow declined the repair as the appliance has a sealed tub (meaning you cannot change the bearings you have to change the complete tub assembly) which would cost you £189 for the tub alone and then you would have to pay labour on top plus VAT. With regard to the wash performance, the problem is that to actually clean dirty clothes satisfactorily you have to force water through the fabric ~ the detergent then lifts or desolves the grime and keeps it in suspension in the water which is then pumped out. On these low water content washing machines there is not enough water to cause this to happen so you get left with half clean laundry. I had to buy my wife a washing machine with a adjustable water level facility for this very reason. By coincidence it was a Creda (same company) My suggestion to you whilst not what you want to hear is to run this one into the ground and then replace it with a suitable replacement.
I would doubt that you have a limescale problem with an 18 month old appliance, much more likely to be a problem with a build up of undesolved washing powder/detergent. I would not expect to get a scalling problem on an appliance less than 5 years old.
Do you use the low temperature washes most of the time?
OK getting late now, if you come back to me tomorrow I will explain things. In the meantime dont be doing any washes at 90C you will ruin your clothes.
Hi John - Not a problem I took yesterday off too - if it were me I would be replacing it with a Bosch or Gorenje - the trick to purchasing another appliance is to look at the Labour guarantee (forget the parts warranty) if the labour warranty is long then the manufacturer expects the appliance to last, if only 12 months then not so long. Secondly see if you can find an appliance with replaceable bearings as many are not sealed units for cheaper production costs. (they dont want you repairing your machine, they want you to buy another)
