Bosch Washing Machine intermitant stopping

[Diver Fred]

Bosch Maxx washing machine display blanks, machine stops at any point in wash cycle. A time, ranging from a few seconds to many minutes, afterwards the display lights up and the machine carries on washing.
Occurred on Hot wash cycle, never reached drain, rinse, spin etc part of cycle.
Have emptied machine of clothes and water - water that was near enough boiling.

Any thoughts, please?
