vokera linea 28 cutting out at 57 degrees

[ray]

good evening ,looking for some assistance, i have a vokera linea 28 combi boiler running on LPG. problem which has just recently started is that the boiler will run until it reaches 57 degrees and then it cuts out.

It will restart when it has cooled down and then it will cut out at 57 degrees again,

i have replaced the high stat thermostat and also the digital pcb board.
There is no error codes when it cuts out and the light is always green.

anyone any ideas , the boiler is for heating my garage and really dont want to spend any more money on it.

any help appreciated

Easy done when you start bud, post around 10 non spamming times (introduce yourself for one post) then apply for the gsr sub forum if you want to talk gas.
