Baxi combi instant 105 HE hot water

[tedley]

Hi,
Trying to sort out my son's boiler. Central heating works ok, but hot water goes cold after a few seconds. When the hot water tap is switched on the water is hot, the temperature lights light up (to 60), and the symbol with the tap on flashes ( i assume this is when there is a demand for hot water). After a few seconds the temp lights all go out, the tap symbol with the diagonal line through it starts to flash and the water runs cold. I am guessing that this may be the water temp sensor, if so, can someone please tell me where it is and is it a DIY job to replace. Thanks in advance
