Triton shower heater kettling query

[John.g]

Ill do the temperature difference Chuck also check flow rate and physical water pressure. Note we have a TW10i on the same water main with no issues.

The 3 phase is not full 3 phase, only a single phase is live as they havent upgraded the tranformer yet. We are PME for the earth. Ive Fluke multi meter.

If I turn the shower temperature down the kettling decreases. Cold water flow, no kettling.

If the above is a actual shower then a thermal cut out (TCO) will trip the power at 48C if the flow rate is too low or the power too high and the water will then run hot & cold, if the temperature reaches a still higher temperature then the TCO will trip and won't reset and has to be renewed, if the temperature is constant looks like something in the water.

Yes has been tested I have a Metro RCD tester with croc clips in this case. It passes and disconnects, plus phase is correct.

Water temperature is constant.

We are in a software area. If it was water related I think the Triton TW 10i on the same water main would have shown issues too, it hasnt.

Did you ever measure the actual flow rate?

IIRC, the T100XR has a water filter on its inlet. This needs to be cleaned periodically. When was this last done?

Testing the RCD is VERY different to testing the circuit properly ……

Never, Ill check that.

I did the Electrical Testing C&G.

That’s not important.

You claim to have tested the RCD -! So what else have you tested on the circuit?

Hipot the conductors, metered the connections back to the consumer unit. Its a 10mm cable too.

A flow test may show up something in view of the above.
Don't know what the shower output is, have done a few calcs based on my mains temp of 8C

KW/showertempdegC/flowrate LPM

8.5/40/3.8
8.5/45/3.3
9.0/40/4.0
9.0/45/3.5
9.5/40/4.3
9.5/45/3.7

Thanks for the info John, I shall check.
