if you have a gate valve on the unit from the hot water tank it could be as simple as the valve on the gas system being clogged going to that bathroom,, from how it is described it sounds like that would be the problem check to make sure all valve are not stuck in the on position ans change the valve if it is frozen in place

"Pres sw open" means there is insufficient air flow. either the vent if blocked, or the blower turns too slow/ or died.

It sounds to me like the heater elements are shot or covered to thickly with calcium to function correctly

This means the solenoid to the modulating gas valve is sharing a fault. You will need to inspect the wiring to the solenoid to make sure it's ok. You can ohm out the solenoid to make sure it's not open. If it is, you will need to replace it.
