This question is regarding Triton Power PCB with Screws - 83315930

Triton 100 XR

My shower starts normally, with plenty of water pressure, then after about 3 seconds the heater indicator red ligfhts go off and there is no hot water, The klixon and all other components are healthy. I suspect the power pcb is at fault, how do I check it to confirm before I purchase a new replacement pcb ?

The things to check first are:

1 That the main valve coming into your house is fully open.

2 Then check that the valve on the line to the shower is fully open.

If these valves are not fully open then there may not be enough water getting to your shower to cool it properly, it overheats the safety device cuts in (TCO) and turns the power off to the elements until it cools down and it all starts again!


Make sure that the shower head is clean and clear, that the hose isn’t kinked (this can happen just behind the hand set where it is difficult to see) also check the inside of the hose although it can look OK on the outside it could have collapsed internally


The other possibility is a faulty flow/stabilizer valve not allowing the correct amount of water into the shower.


There is a link below that explains the above.

Good morning,

I have checked all the components that you listed below, which all are healthy. I still suspect the fault lies with the power pcb or the cover pcb. Can you help me with information on how to test both pcbs so that I can replace one or both of them. They are expensive components to replace so I want to be sure that the pcbs are faulty before paying for replacement parts

Thankyou

The only way to check for a faulty pcb is by substitution.
