Shower not reaching set temperature

[Johntheo5]

Any update on your shower Mark?.

Hi not as yet, not had chance to double check the wiring and switching to max hot and back down again.

I did use the shower this morning and it worked as it should straight away.

So all the wiring looks fine. Removed from the terminal blocks in the shower and re-inserted/tightened.

Power back on.
Turned the shower on hot (setting 6) and heated up in around 7 seconds.
Turned then shower off.
Heard the tco click around 20 odd seconds.
Power off to to the shower.

Powered back on.
Turned on hot (setting 6) and heated up in around 30 seconds (expected)
Turned the shower off.
Heard tco click around 20 odd seconds again.
Power off to the shower.

Powered back on
Turned on hot (setting 6)
Waited around a minute and the temperature did not rise.
Briefly turned temperature upto maximum and then back to 6.
The shower then started to heat upto the correct temperature.

You might have a look at the isolator switch wiring as well.
It seems that switching on at the isolator causes more problems when you switch the shower back on?.
Turning the temperature control briefly to hot will cause the dynamic pressure to rise which may then be causing the pressure switch to close the heating elements micro switches although a flowrate of 8LPM at full flow would indicate that the pressure is quite adequate and the problem may be a faulty pressure switch, difficult to convince Triton of this though.
Leave the shower on for a minimum of say 90 secs after it's fully up to temperature at setting 6, then switch off, it shouldn't take 20 sec to open the TCO, mine will open in not more than 12 secs and generally takes 10 secs.

Powered back on.
Turned on hot (setting 6)
Waited around a minute and the shower did not heat up. Hot at the very start, then went to luke warm and then freezing cold.
Turned setting to coldest for 3 seconds then back to temperature 6.
After around 40 seconds the shower heated up but this time the water was alot hotter than it should be for setting 6, borderline scorching.
Turned off the shower and heard the tco click.

Can you measure the flowrate again at setting 6?
Shower filter is clean?

 

[MarkWilliams363]

Flowrate at setting 6 was around 10 seconds.
Wheres the shower filter? I would imagine its clean as the showers not even that old.

 

[Johntheo5]

Flowrate, 6.0LPM, should definitely not be a problem.

Filter, It will show it in the MIs, you will have to remove the cover.

 

[MarkWilliams363]

Bugger means messing about with the compression fitting.

 

[MarkWilliams363]

So had the shower off the wall again. The filter looks clear to me (gave it a blow) as i couldnt see how to remove it.

Really don't know what you can now check out apart from the isolator switch, Triton may give you a replacement shower if you deliver that one to the nearest branch.

Phoned Triton last week and I made it clear I was very unhappy with the service and I would of been better off purchasing from a retailer as opposed to the manufacture as I could of return the faulty item. (with them you have to wait for a service engineer to come out and inspect)

Triton engineer is due this Thursday at some point for an inspection of the shower.

Has the engineer attended??.
