When I plug the machine in, only the top power light goes on. When the power switch is on the boiler light does not go on. The only switch that seems to work is the brew switch. Nothing happens when I turn on the steam switch either.

Relay will be fine if you fix the real problem. Get some new seals (5 of them) into the steam boiler and check for leaks from the teflon tube at the top of the steam boiler. When you have it apart tip it upside down, you will be surprised how much hidden water there is.
There is a reset button inside on the front side of the boiler (you have to take the top of the machine off. There are 4 screws and remove the water tank). It is located between 2 black wires and is a red button. Push it in and test. There is also another problem that you might have. If the brew thermostat is bad it won't heat. To test for this, push the steam switch and wait 15 seconds. Then open the steam knob and push the middle button and see if the water is warm. If it is then you need a new brew thermostat. That is the thermostat that has the red dot on the top. It sets on top of the boiler next to the steam thermostat. If you take the top off, make sure that the machine is unplugged.
If none of these things work check the heating element with an ohms meter. The reading in the terminals should be from 12 to 16 ohms. If no reading the elements is bad and you have to replace the boiler.
Open the steam valve when you turn the machine on that will vent out the boiler, keep it open until it starts to hiss slightly and produce small steam bubbles, then close and machine should heat to temp. If that solves your problem then the vent valve needs to be replaced, until then you can turn using the steam valve open trick.
It is on the right side of the machine behind the grouphead if you remove the top panel you will see te box with the red switch sticking out. MAKE SURE THERE IS WATER IN THE MACHINE FIRST!!!!!! Do not trust the sight glass, if the level probe is in there, turn machine to 1 then disconnect the electrical connector on the side of the sight glass, the pump should kick in and water will flow in the boiler, if the level does not increase in the glass, then the machine turned itself off because the element got too hot from lack of water. The hole for the sight glass is blocked.
This is a cold boiler problem.
There are several reasons for a cold boiler...boiler element is open, no power to the boiler element, thermostat is not functioning properly, or it could even be a board problem not delivering voltage to the boiler.
First start by opening the top and reseating all connectors on the board, if this does not help then you will have to extract the insides of the machine from the case to get at any of the boiler and thermostat hardware.
Start by removing the 1 screw holding the inside workings to the outer case. This is located on the right top side of the machine beside the grinder.
Use great caution while pulling the guts out of the case and watch the dredge drawer switch does not hang-up on the case. Snake the power cord through the bottom of the case while pulling the inner workings out of the case.
There are 2 elements in the boiler check them both for a resistance (they will not be the same resistance) if either are open then then replace the boiler. Check the thermostat on the back of the boiler for resistance, if open or shorted, then replace. Check thermal breaker on boiler, this should be shorted if not, reset it by pressing the button in the center of the breaker.
If none of this works then you will have to depress dredge drawer switch front door switch and insert the brew group to depress the brew group switch, plug in the unit and turn it on.
Check for voltage on the elements on the boiler.
If no voltage then check all connections.
If you have gotten this far there is a good chance it is the board fault and it will need to be replaced.
Be shure to label all connections to the mother board as there are several connectors that can be placed in the wrong position while reassembling.
NOTE: This depth of trouble shooting should only be attemted if you are completely comfortable with electrical/electronic repair.
Hmmm. It doesn't sound like a boiler problem. The heating element is controlled by a pressure or temperature switch. Either the switch is poorly connected or malfunctioning. Temp. switches are directly on the boiler with wires that go to a relay connected to the heating element. Pressure switches just have a tube connected to the boiler with wires to the relay.
