Machine set for 1.54 cycle. got to the last 18 minutes and flashed up error 90. No such error in the manual - only up to error 20.

E90 is a communication issue with the display user interface and the main PCB.If you take the lid off you will see a blue wiring loom going to the display.where it connects to the display can get bad connections and needs taking apart and cleaning on the PCB contacts
