Do you get any error codes such as a limit opening? Sometimes a limit will open cutting the heating element off and on
Do you have an amp meter to check amp draw on element and see if it is drawing proper amps and staying on?
OK can you send me a picture of wiring diagram and label showing nomenclature of unt?
From looking at the diagram it looks like you have 2 elements.One may be bad. Locate the elements, disconnect wires at elements and ohm the elements to see if perhaps one is open.
Picture shows 2 heaters. Do you see the other heater terminals .Back up and take a pic a little farther bback
Should be 2 more terminals like these
Sorry for some reason I did not get your reply earlier. Did you disconnect the wires to check the ohms? And on call for heat, do we get 230v between these wires?
OK ohms is good. And the 110 to ground is good, but do we have 220 between? And is the 110present on each wire if test disconnected?
OK element sounds like it is good.The only thing I could think of is if it cutting out periodocially The elements do not get "weak"
Do you have a clamp on meter to clamp around wire and see how many amps it draws?
I wasn't able to locate a manual with this is why I asked about label with nomenclature. There should be a label somewhere that says voltage, amps, model, serial and things like that.It should list amp draw for pumps and element individually.
If it says 4.5 or 4.8 KW we should be drawing roughly 19 to 21 amps
I have that one but it is just a users manual. No service data included.
WE want amp meter clamped around one wire to element only.
Do you have voltage to those terminals but still no amps?
OK element is bad then.
I did read in one of the manuals from case and element we should read at least 1 million ohms.
This is from case to terminal. Lets check that way.
Found that today on page 10 in this manual
I am going to say if we have power to the element but element draws zero amps, we have a bad element
