Triton T80si going cold intermittently

My T80si shower keeps going cold intermittently. It can be OK for the full shower or sometimes goes cold three or four times during the shower. When it does go cold no-one is using water elsewhere in the house so it's not low pressure. The flow rate at the shower head doesn't seem to change. Can you give me a clue?

Thanks

If the shower is cycling hot and cold then it sounds like lack of water presure to the shower or one of the following below?

Things to check for:

Lack of water pressure to the shower (Check Stop tap is fully open supplying the shower)

A leak inside the shower (Check the pressure switch diaphragm on the stabiliser valve at the top for leaks)

Wire terminals inside melting? (Check the TCO on the outlet pipe under the can and any other terminals visible)

The Outlet TCO on the outlet pipe is a usual suspect due to the terminals not having a good connection causing the wires to arch amnd melt, if this is the case then you need to replace the outlet pipe with TCO ( Item no 10) from this link provided to your shower - http://www.showerdoc.com/shower-spares/triton/TRITO-PARENT-12-Triton-T80si

If the shower goes cold and stays cold for about 10-15 mins then it sounds like the TCO on top of the heater can is cutting in a nd the shower is over heating and causing this problem.

This could be down to a stabiliser valve problem.
