Check the cables and connectors. If Ok then problem is in cuicuit board.

A malfunctioning control panel or membrane can cause erratic behavior in your microwave oven. If the control panel is not registering the start command correctly, it may interrupt the cooking cycle. Try cleaning your membrane and control panel with a soft and damp cloth to remove the dust.
If cleaning doesn't resolve this issue, try resetting the microwave oven by unplugging it from the power source for a few minutes, and then plugging it back in.
The microwave may not generate the required heat to cook the food properly if the magnetron or high voltage capacitor is defective. This could lead to the timer counting down without any heating action.

H:H 80 on a Miele microwave indicates that the microwave's Keep Warm feature is in use. To end the cycle, open the microwave door or operate a selector or sensor (press a button (not the time display) or turn the selector knob). The keep warm setting runs the microwave for 15 minutes at 80W power starting 2 minutes after any program that used more the 450W of power. You can turn off the Keep Warm feature completely in the microwave settings. To change the setting, touch the menu button (arrow and three horizontal lines). Press OK and turn the selector knob until you see P9. Press OK and then turn the selector knob to change the setting. Press OK to save.

I found this in the manual for one of the Miele microwaves, http://static.appliancesconnection.com/attachments/D1418829486.pdf . on page 30. The section on changing the settings starts on page 40.

I hope this helps.

Sounds like a bad switch should have three primary, secondary, and monitor switch after 5 years change all 3 they are not the same primary and secondary are NO ( normally open ) and the monitor NC ( normally closed ) unit will not come on the fuse on the filter board is blow this usually shorts out the filter board change the switches first and replace fuse may not have to replace filter board hopes this helps.

Power Supply

Check whether there is a proper power supply. Look to see whether the cord is connected to a grounded 3-prong outlet and the cord is fully plugged in. If the electrical system is built-in and no power cord is visible, replace or reset the household fuse or circuit breaker.

Microwave Functions

Some basic microwave operational steps may affect whether the microwave is heating. Open and close the microwave door, as the unit will not function with the door open, and push "Stop/Clear" to cancel any previous settings, such as the timer, which do not heat the microwave oven.

Setting the Microwave

Once the power to the microwave has been reset, or verified as working, and the microwave is ready to run, select a new cook cycle and press "Start" to see if the microwave begins to run and cook food as expected. Allow the food to cook for the alloted time and then open the microwave door and check to see if the food has cooked or heated. Choose a longer cooking time and restart the microwave if food is heating but is cooking slowly.

Repair

If all efforts to troubleshoot the function and power to the microwave still do not get the appliance heating food as expected, there may be a repair issue that needs to be addressed. Contact professional technician for advice.

Burnt wires or connections at or bad door switch.

This is a list of possible causes. 1. Defective triac or relay 2. controller is confused (pull power cord for a minute and see if it resets) 3.Defective controller or touchpad.

That's how it would sound if you were cooking on a power level less than full power.

If you enter the cooking time and hit Start, it should cook at full power by default and not cycle like you describe.

If you are using some sensor cook setting or automatic type cooking setting, it may cycle like that normally.

The first thing to try is a "hard reset". Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.
