Thanks for the question.
You said you have 220 volts to the switches what about the H1 and H 2 they should also get 220 volts if you don't then the switches are burnt .
Look for number 54 and 54 a in the breakdown its the switches you need if their burnt out.
Heres the wiring diagram for the model check between L1 and L2 at the switches if your not you blew a breaker try resetting the breaker .
I see thats why no 220 to the switches great job in finding the problem.
Thanks and God Bless.
