ecologixx7 wtw86561gb/02 any suggestions ?

Switch on and after approximately 30 seconds whole machine switches off – no power to screen or dryer. Turn disl to off, wait 15 seconds and power is back on.
Pump works as can see water in tray compartment and any water I put in front drain returns to removable water container.

Machine is 2 years and 11 months old.

Have always removed lint from filters after every use. Never hadn’t water full as emptied after every cycle. Sensors in drum cleaned every now and again as per instruction manual. Paid lots and did not expect problems so soon.

Am worried it might be something serious or expensive and is it economical to repair or discard and never buy Bosch again?

Why no error codes like waging machines?

Thanks in advance Simon
