220 and MWBC Curcuits all dead

Suddenly the other night all of the 220 and the MWBC in our house have no or maybe half power.

All the plain 110 circuits work fine.

The dryer has a control panel that will power up, but the motor will only whine and can't spin.

Obviously we have checked and rechecked the breakers and none are tripped.

Looks like about 4 completely separate circuits are not functioning correctly.

Anybody have any ideas? We were not even home when it happened and nothing was running while we were away.

Turn off all the double ple breakers and see more circuits go dead. They could be back feeding through the 240 volt devices.
