Vokera Excell 96e Boiler Fault

[jy965497]

Any suggestions please:

After a short period of operation, burner switches off and boiler appears to lock-out on both CH and HW only setting. Flue diagnostic LED illuminates and status LED flashes. And then seems to auto-reset, start up, operate for 30 secs, then repeat - 10 secs off, 30 secs on. Result is alternating hot / cold through shower and taps. Burner does not modulate to maintain constant heat. Temperature rising too quickly?

Have replaced diaphragm, thermistor, 3 port valve, all last year, air pressure switch, flue (corroded), and PCB this year as well as a basic service, cleaned venturi and inspected fan.

Thanks

This plumbing forum will not provide advice to anybody with regards to boiler repairs or any other form of gas plumbing without you first providing us with your Gas Safe Registration number in a thread - for very obvious reasons. If you're not qualified to touch gas, you should stay well clear of trying to!

Would have been cheaper for you to buy a new boiler
