I am not an electrical person so please pardon my lack of knowledge. I have reading all info on the electrical elements in the aqua hots, I have a 600 unit. They seem unable to maintain hot water as them used to after last years trip. I am asking how they can be tested to see if they have lost heating ability without taking the unit apart. And if they are not up to par how difficult are they to replace. Remembering that I am not a mech and usually just a gopher running for tools. Also is there anything else I should look for or just call the local RV repair guy. Any assistance will br greatly appreicated.
