I have the same problem, hot for 10 seconds, cold then hot again. I have checked that the flow rate isnt restricted and following advice from the technical department, I have ordered a Thermal cutout part. Will change this and report back on my findings.

Hi
I am having the same trouble, I have taken the cover off and found that there is a loose conection (wires are all burnt) on the thermal cut out switch that is connected to the outlet pipe (item number 5 in the user guide). I will order a new one and let you know if it works
