Dishwasher (Oulton Broad NR32)

Bosch SMS6ZCWOOG. White. Manual. Works sometimes but we continue to receive an error code. May be something to do with the drying system - Zeolite - but unsure. With no knowledge of repairing such items we decided to buy new. Shame because it is only just over 2 years old. Usually Bosch last a lot longer. I hope someone with the skill and ability to diagnose and fix will take it, otherwise we will make sure it is recycled sensibly. Dean
