The power comes on but i cannot get it to start. No response from any buttons apart from power button

It seems like you're experiencing an issue with your Panasonic microwave oven NNT551. If the clock button is not responding and you only see two dots when pressing the stop button, there might be a few things you can try to troubleshoot the problem:

1. Power Cycle the Microwave:
   • Unplug the microwave from the power outlet.
   • Wait for about 30 seconds.
   • Plug it back in and try setting the clock again.
2. Check for Child Lock:
   • Some microwaves have a child lock feature that can prevent certain buttons from functioning. Check your manual to see if your model has this feature and how to disable it.
3. Reset to Default Settings:
   • If there is an option in the manual or settings to reset the microwave to its default settings, try doing that.
4. Inspect for Physical Damage:
   • Ensure there is no physical damage to the control panel or any other part of the microwave that may be affecting its functionality.

Turn off the circuit breaker inside the panel until landlord can repair it.

To clean it , you need to take the printer apart.(messy)

Try resetting the error message:

1.With the printer powered off but connected to a power source,
press the Power button while pressing and holding the Stop/ Reset button.
2. When the Power is lit, press the Stop/Reset button two times
while pressing and holding the Power button.
3. When releasing the Power button and the Stop / Reset button (regardless of order),
the printer will move into a service mode. (Waiting for menu selection)
4. When the on/off lights in green, press the Stop/Reset button the
specified number of time(s) according to the function listed in the table below.
(Each time the Stop/Reset button is pressed, the LED lights alternately in orange
and green, starting with orange.)

Note: press 4 times for waste ink counter reset.
