Scalding hot water

The things to check firstare:

1 That the main valve cominginto your house is fully open.

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

If these valvesare not fully open then there may not be enough water getting to your shower to cool it properly the overheatsafety device will turn the power offuntil it cools Then it all starts again

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

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

A rough check is to remove theshower head turn temperature control to fully hot the water coming out of thehose should be a bit more than a dribble then turn to fully cold and it shouldbe coming out at full flow.

Ifthere is not much difference between the two then you could have a faulty flowvalve.

Carry out this checkafter you check the inlet valves.

Also as it is a Triton have a look at the outlet TCO

The outlet Thermal Cut Outthis is a black disk with two wires going to it and it is mounted on the out letpipe (The bit between the heating tank and thehose)

Examine theconnections closely if you see any discoloration / signs of overheating then theTCO needs replaced.

Open / close the safety device that allows power throughto the elements
