I inherited a Spazio EK espresso machine, and the boiler won't heat up (I think the water level got too low). Is there a reset switch that will fix this, or am I out of luck and have to replace the heating element?

It does not say, what causes high level of water in the steam boiler. ... High pH in your water supply can cause foaming and water feeder troubles; .... I have a clearenough understanding of the condition of your water feed valve .... My system has separate McDonnell and Miller automatic water feeder and Low water cut off.
Problem is either the element, the pressure stat or the reset thermostat on the boiler left side if the model is equipped with one, has tripped, possibly because the machine is low on water in the boiler or the contacts for the pressure stat are damaged or dirty. First I would check the water level in the boiler then remove the left side panel and check the reset switch and press it in, then turn on machine to see if it heats up. If you do not have a reset switch on the machine then check the element and pressure stat to make sure they are working properly, do a resistance test.
If the red light is on then the machine is not getting water and or level is low in boiler. Try this remove the bell looking softener and run it under the faucet to see if water flows through, it could be that is blocked and not letting water through, and if so then the reset switch for element might have tripped because machine has low water.
Check the wire on the water reservoir to make sure that it is properly connected.
Check to make sure the wire connection is clean and making good contact.
If the machine turns on the connection is dirty, so you will need to remove nut and clean.
There is a level probe on top of the boiler (actually 2) The right one (yellow wire) is the low level probe and it will not let the boiler turn on unless it sences water at the probe. If it is scaled it can't tell if there is water in the boiler and the element will not heat. Remove and clean the probe.
Yes the machine should not be left on for that long, it only takes a few minutes to heat up. It does not have an auto refill if the boiler is low on water. If it heats up the water in the boiler for over an hour, it is safe to assume, that the water might at some point turn to steam, when you use it for the first time, it flushes out all the steam, and fills the boiler with water.
When you say no pressure do you mean steam pressure or water pressure? If it is steam pressure the machine is not heating up, then the elements could be damaged, disconnect the machine from power open top 4 screws on the top panel, you will see the boiler and element(middle of the boiler with 1 wire on each of the terminals) disconnect both of the terminals and check for resistance between the terminals, if you get a reading then the element is fine.
The bottom level sensor is not reading the water level and told the machine to not heat(stainless steel probe sits on top of the boiler there are 2 of them one checks the min water level and other checks the max water level, disconnect one of them and using ohms meter check reading from the stainless steel level to the top of the boiler, if there is a reading connect and then check the other one using the same method. If there is no reading on any one of those they might be covered with scale buildup or there is no water in boiler.
The machine cannot read the water reservoir(screw with ground connection on water tank).
There is also the Pressure stat(black box which sits on top front right of the machine with 2 electrical wires going to it), remove wires and check with ohms meter.
