I did think flow switch but couldn't understand why it would initial fire up

Could be sensing flow and then no flow etc

Customer sent me a vid of what it's doing but I can't really see much unisual

Post it up

Is she fit?

Is she fit?

Well she's only 24

Won't let me. Trying to do it all on phone but it's having none of it

Sure its trying to re-light and its not the pump pulsing? It does that when it overheats from a blockage in the plate.

 

[Riley]

Well from the video of it she sent me it never actually locks out so that could well be reasonable

Riley, (knowing that you have said that the heat side is ok) I am still going to go with...low gas pressure as the sequence you describe is about right, burner fails and tries again (5 times?) saying that flame rectification is almost the same or just ignore this as I am only trying to bump my posts up!

The pump pulses like every 10 seconds or something. Ignition failure would lock out after 3-5 attempts and would need resetting. Tell her to leave the heating off until the flow and return go cold. Then run the hot water and see if its dumping down the flow. If it is then its nearly always the plate. Diverter motor would also be worth a check though.

No lock out? I think you have a blocked plate. I had this last week. I replaced the plate and it runs on hot water like a dream
