Thanks for the reply "Dannyboy". Checked connectors and this appeared to work - or at least seemed to allow machine to start - but E91 code has appeared again. Will take connectors completely off and try to clean as you suggest. Many thanks. LB

take lid off.find blue loom with 5 wires that goes to the front display /buttons user interface and where it attaches to the pcb they get a bad connection and cause E90/E91 error codes.wire needs removing from pcb and connections tightening (bend them slightly with a needle) and the pcb tracks need cleaning.reconnect and hopefully all will be well.
