i have bought a second hand microwave 2 yesterday and i have a problem.

when i started it up yesterday everything worked great but when i started it up this morning the display says:

MW2P V1.3 waiting from host PWM 000

+000 +000 +000 +000

When i push the other buttons nothing happens even when i start i up several times.

Can anybody help me?
