My vokera linea 726 central heating intermittently doesn't refire after temp reached and it cools.
This usually occurs daily though may work okay for several hours and can be refired by opening the hot tap. Then after firing and refiring for another hour or two it may not refire again. It has only given a Code 01 warning once, otherwise it just clicks as if trying to refire.
Pressure reading is 1, goes up to 1.3 - 1.5 when working and falls back to 1 as it cools. The hot water always fires when a tap is opened and central heating always refires when a hot tap is opened.
Any ideas? Thanks for any help.
