excellent analysis.

I'll just add that GFCI's are a lot of times, failure prone.

I responded to one of the guys who responded to you. GFCI outlets are often used to protect circuits in wet areas, so the can be affected by other items and affect other items as well. And it will typically react quicker than a typical thermal/mechanical type circuit breaker which will require time (albeit a minimal small amount of time) to heat the element up. Ground fault protection is require for all circuits in wet areas.

Pics do help, BTW

Indeed, I should have posted that, I failed to notice he had not yet reset the GFCI.

Bathrooms are protected by gfci's now.
Doubt its your fan if it happens when turning your switch off.
Turn the power off to the bathroom.
Unscrew your switches and pull them out slightly
The wires in the box should only be power in/ power out and ground.
There should be a ground wire connected to each switch and the grounds may all be connected together.
Look to see if there is any excessive ends (after they are twisted together or after they are wrapped around the ground screw.
Trim the excess
Make sure there is not excessive bare wire on the circuit wires
Wrap the switches with electrical tape
Put switches back turn power back on
Switches are very cheap so replace them if you want

My guess is a ground wire is close enough to a screw or bare section of wire that it went to ground when turning the switch off

If any of this makes you nervous or your confused hire a professional or watch a youtube how to video.

I rewired my entire house and garage, its not rocket science but you also cant just wing it.

Edit
If you can pull your switches out an inch or so and take a pic i can probably help.

This is all assuming the problem is in the bathroom (which is probably correct, according to your story).

If you called an electrician this is what would happen:

Would check the GFCI, and probably change it.

Check switches, and probably change them as long as they were single pole switches, and not some weird triple stack switch, or OEM dial that came with the HVL.

Right now you are into the electrician for about $165-175.

If the GFCI still trips, it's obviously the HVL, at which point the lecco offers to change it out at a cost of about $250-350 (or more), depending on what kind of HVL you want. (Why not change the bad part? May not be available or available for a reasonable price. Chances are that it may cheaper to replace the whole unit.)

Oh, and don't forget about the patching and painting that would need to happen if the new HVL is a different size/shape than the old one.
