Question about Vanguard International Vanguard 82V66-2T Electric Water Heater
From the power source, the first electrical devices are called relays, right? Well, one of those is smoking and smells like burning plastic.This happened after being doused with water from abig leak. I'm not sure what these are called so I can replace it.
I have a Boilermate Premeir with a Smart Control. I believe this is called a parasitic system and operates off a zone off the house's forced water heating system. The system has been installed for several years. We did have a problem with pipes freezing in the winter. I repaired the pipes and repressurized the system, though sometimes the system loses pressure and I add water again. I did bleed the air from the broken loop.
Now, the smart control of the Boilermate has a minus before the "On". It looks like -On. Sometimes the minus flickers. Sometimes it looks like the display will go off altogether and lately that has happened. The smart control makes a fairly loud buzzing noise, similar to a ******** motor.
It is on a 24v system. Sometimes, when its display is flickering I hear relays or solenoids on the boiler itself flick on and off. Sometimes the whole system shuts down. Then I must turn off the switches on the boiler, wait a bit, and then sometimes things seem almost normal when I restart things. The situation is getting worse.
Any things I should check? I have a meter and some electrical experience.

You are correct. They are relays. A low voltage operates a higher voltage.
