Can anyone please help.............!!
New Vokera Maxin 28e Boiler installed in 1998 and radiators renewed in 2008.
System serviced annually.
One day last September, came back from work and my wife said that the Boiler had suddenly had a "violent shaking fit" and she had switched it off.
We switched it back on and it restarted OK.
Over the winter, we had intermittent problems with the red light coming on and Boiler cutting out. Seemed to be that if the central heating was on then the red light might come on when hot water was switched on at a tap. Or the red light could just come on without the hot water tap being turned on.
Normally, the Boiler could be switched back on immediately but sometimes it had to be left for 15-20 minutes, presumably to cool down.
Also noticed that on some of these occasions, the tap water would be excessively hot.
When on holiday for three weeks at Christmas/New Year, we left central heating to come on intermittently and neighbour who was checking daily reported that the red light came on once. He reset.
We now have a leaky joint at the penultimate left hand copper pipe from the underside of the Boiler. Perhaps brought on by the "shaking fit" in September.
Have checked water leaking out with a clean steel nail in a jar and it rusts. Presumably, the Plumber did not include an inhibitor when refilling after new radiators fitted.
After new radiators fitted, with 1 No. additional and a slight increase in some of the sizes, we had problems with the pressure dropping. The Plumber fitted a small expansion tank. This solved the problem and the pressure is now steady at just slightly over 1 bar for long periods.
We called out the Plumber to investigate the red light problem and he removed a 'Restrictor' in the flue pipe which he said was no longer required. However, he could not diagnose the red light fault and thought this could be any number of things.....!!
Over the Summer, with no use of the central heating, we have had no red light problems when using tap hot water only.
Does anyone have any idea why the Boiler would "shake violently" and what the solution to our red light problems could be...........??
