Looking for some advice on a 8yr old Vokera linea 24 with a strange overheating problem.
When The DHW is turned on the boiler ignites but the flame kind of pluses but start to heat the water up, Then the system locks out on the e02 error.
We had it serviced and explained this to the engineer he tested everything and suggested it was either the DHW stat or the safety stat. I got both replaced and both parts tested with a meter and seem to be ok but the fault is still there with the boiler.
If I turn the hot water knob down low so the water is only 45deg max we seem to get away with the boiler not heating but if we want it any higher after a few mins running it gives the e02 error.
Another problem I have noticed lately when I put it back to reset after a fault, then try to turn It onto hot water I get a clicking\ticking noise as the flames trys to ignite the boiler seems to power down (LED and numbers off) then goes through this again until finally its working.
I hear the ticking noise for a while while I run the hot water and watch the flames seem to pulse as it goes up to temp, The noise eventually goes away its self.
I am not sure what else to do with this as it looked like a faulty DHW stat would have been the cause but replacing it didn't solve the overheating.
Any advice would be appreciated
Thanks
