How can I fix my vokera linea ag plus?

I have the same problem with taps or showers. Checked again, hot tap turned on and the boiler ignites, flame on for approx 1 and a half minutes, flame shuts down for approx 12 seconds and carries on following this cycle while the hot taps or shower is on. Turned up the thermostat on the heating and that works fine, boiler ignites and runs constant until thermostat is turned back down. Thanks

is it ok with the taps? if so then the flow rate through the boiler may be too low for the showers, or the shower thermostats may be faulty.
