what is a pcb test and tct test
I don’t know what you want to checkfor on the PCB but I guess that you need to check that the power is going intoit in the correct places and the power going out to the elements solenoid valveetc. Is there when it is called for by the board on the front panel
Faulty Thermal Cut Out
A faulty TCO will have no continuity across the twoterminals (The black thing on top of the heating tank)
Therefore a good TCO will have power at bothconnections and a faulty TCO will have power at only one.
(The function of the TCO is, if the water over heatsit cuts the power off to the elements until the water cools, this can take upto 15mins)
