Okay. So either it’s pulling too many amps…or there’s a problem at the electrical source (i.e., the outlet, the breaker, etc.)
Â
Did you test the unit with an amp clamp and compare the reading to rated wattage? Here are the basic formulas to determine what the amp draw should be:
Â
Â
If the amp draw is good, then there’s a problem with the source. If so, call a licensed electrician. Equipment technicians aren’t usually authorized to deal with a building’s electrical issues.
Â
If the amp draw ISN’T good, then there’s a problem with the unit. A schematic might help. However, the model you provided proves useless beyond the C5 part.Â
Â
Anyway, with a good model # and some known operating parameters derived from that, a schematic can be used along with a DMM to troubleshoot it.
Â
Here’s an example of a schematic.Â
Â
Â
This may not be the correct one since most of their manuals include four or five of them as they’re relevant to a specific unit’s incoming voltage, wattage…and geographical market. So, you’re better off using the one in the unit.
Â
If all this is a bit much for you, then call an authorized service provider for the equipment. Here’s a link that will guide you there:

I hope this helps…

Some other ideas to look at.
visually inspect heating element?
they could have a slight crack in them.Â
Loose or burned terminals by element could cause high resistance.Â

A good thing to check. However, a high resistance does NOT cause an over-amp condition. A high resistance causes just the opposite.
Resistance goes UP – current flow goes DOWN. Ohm’s Law.
